I am looking for for an example to calculate the timediff between to TIMES (24h) minus break time in H:m format;
Starttime: 08:30
Endtime: 17:30
Break: 01:50 (means break time 110 Minute Break time)
Netto working hours should be: 07:10 (7h10m) and 7.17 as decimal..
Is there an example?
I will appreciate your input.
Thanks
there are others ways to do that but to calc this time difference you have first to transform yours timestamps into seconds, then after you calculate it as seconds, transform to timestamp again to show up. like in the code:
HTML:
<html>
<label>Start Time</label><br>
<input id="start" value="08:30"><br>
<label>End Time</label><br>
<input id="end" value="17:30"><br>
<label>Break Time</label><br>
<input id="breaktime" value="01:50"><br>
<br>
<label>Difference Time</label><br>
<input id="diff"><br>
<label>As decimal</label><br>
<input id="decimals">
</html>
JavaScript:
function getTime(seconds) {
//an hour contains 60 * 60 = 3600 seconds
//a minut contains 60 seconds
//the amount of seconds we have left
var leftover = seconds;
//how many full hours fits in the amount of leftover seconds
var hours = Math.floor(leftover / 3600);
//how many seconds are left
leftover = leftover - (hours * 3600);
//how many minutes fits in the amount of leftover seconds
var minutes = Math.floor(leftover / 60);
//how many seconds are left
leftover = leftover - (minutes * 60);
return ('0' + hours).slice(-2) + ':' + minutes;
}
function getSeconds(timestamp) {
var hms = timestamp + ':00'; // your input string
var a = hms.split(':'); // split it at the colons
// minutes are worth 60 seconds. Hours are worth 60 minutes.
var seconds = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]);
return seconds;
}
function getDecimals(timestamp) {
var hms = timestamp + ':00'; // your input string
var a = hms.split(':'); // split it at the colons
//To get the total decimal hours we use the formula: h = hours + (minutes / 60) + (seconds / 3600).
var decimal = (+a[0]) + ((+a[1]) / 60) + ((+a[2]) / 3600);
return decimal.round(2)
}
var endTime = document.getElementById("end").value;
var startTime = document.getElementById("start").value;
var breakTime = document.getElementById("breaktime").value;
var diff = getSeconds(endTime) - getSeconds(startTime) - getSeconds(breakTime);
document.getElementById("diff").value = getTime(diff);
document.getElementById("decimals").value = getDecimals(getTime(diff));

This is a common problem but I'm not sure how to solve it. The code below works fine.
var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
However, when I get to 1 hour or 3600 seconds it returns 0 minutes and 0 seconds. How can I avoid this so it returns all the minutes?
To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):
const minutes = Math.floor(time / 60);
And to get the remaining seconds, multiply the full minutes with 60 and subtract from the total seconds:
const seconds = time - minutes * 60;
Now if you also want to get the full hours too, divide the number of total seconds by 3600 (60 minutes/hour · 60 seconds/minute) first, then calculate the remaining seconds:
const hours = Math.floor(time / 3600);
time = time - hours * 3600;
Then you calculate the full minutes and remaining seconds.
Bonus:
Use the following code to pretty-print the time (suggested by Dru):
function str_pad_left(string, pad, length) {
return (new Array(length + 1).join(pad) + string).slice(-length);
}
const finalTime = str_pad_left(minutes, '0', 2) + ':' + str_pad_left(seconds, '0', 2);
Another fancy solution:
function fancyTimeFormat(duration) {
// Hours, minutes and seconds
const hrs = ~~(duration / 3600);
const mins = ~~((duration % 3600) / 60);
const secs = ~~duration % 60;
// Output like "1:01" or "4:03:59" or "123:03:59"
let ret = "";
if (hrs > 0) {
ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
}
ret += "" + mins + ":" + (secs < 10 ? "0" : "");
ret += "" + secs;
return ret;
}
console.log(
fancyTimeFormat(1),
fancyTimeFormat(10),
fancyTimeFormat(100),
fancyTimeFormat(1000),
fancyTimeFormat(10000),
);

For people dropping in hoping for a quick simple and thus short solution to format seconds into M:SS :
function fmtMSS(s){return(s-(s%=60))/60+(9<s?':':':0')+s}
done..
The function accepts either a Number (preferred) or a String (2 conversion 'penalties' which you can halve by prepending + in the function call's argument for s as in: fmtMSS(+strSeconds)), representing positive integer seconds s as argument.
Examples:
fmtMSS( 0 ); // 0:00
fmtMSS( '8'); // 0:08
fmtMSS( 9 ); // 0:09
fmtMSS( '10'); // 0:10
fmtMSS( 59 ); // 0:59
fmtMSS( +'60'); // 1:00
fmtMSS( 69 ); // 1:09
fmtMSS( 3599 ); // 59:59
fmtMSS('3600'); // 60:00
fmtMSS('3661'); // 61:01
fmtMSS( 7425 ); // 123:45
Breakdown:
function fmtMSS(s){ // accepts seconds as Number or String. Returns m:ss
return( s - // take value s and subtract (will try to convert String to Number)
( s %= 60 ) // the new value of s, now holding the remainder of s divided by 60
// (will also try to convert String to Number)
) / 60 + ( // and divide the resulting Number by 60
// (can never result in a fractional value = no need for rounding)
// to which we concatenate a String (converts the Number to String)
// who's reference is chosen by the conditional operator:
9 < s // if seconds is larger than 9
? ':' // then we don't need to prepend a zero
: ':0' // else we do need to prepend a zero
) + s ; // and we add Number s to the string (converting it to String as well)
}
Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).
2020 UPDATE
Using basic math and simple javascript this can be done in just a few lines of code.
EXAMPLE - Convert 7735 seconds to HH:MM:SS.
MATH:
Calculations use:
Math.floor() - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor
The Math.floor() function returns the largest integer less than or equal to a given number.
% arithmetic operator (Remainder) - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder
The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.
Check out code below. Seconds are divided by 3600 to get number of hours and a remainder, which is used to calculate number of minutes and seconds.
HOURS => 7735 / 3600 = 2 remainder 535
MINUTES => 535 / 60 = 8 remainder 55
SECONDS => 55
LEADING ZEROS:
Many answers here use complicated methods to show number of hours, minutes and seconds in a proper way with leading zero - 45, 04 etc. This can be done using padStart(). This works for strings so the number must be converted to string using toString().
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart
The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.
CODE:
function secondsToTime(e){
const h = Math.floor(e / 3600).toString().padStart(2,'0'),
m = Math.floor(e % 3600 / 60).toString().padStart(2,'0'),
s = Math.floor(e % 60).toString().padStart(2,'0');
return h + ':' + m + ':' + s;
//return `${h}:${m}:${s}`;
}
console.log(secondsToTime(7735)); // 02:08:55
/*
secondsToTime(SECONDS) // HH:MM:SS
secondsToTime(8) // 00:00:08
secondsToTime(68) // 00:01:08
secondsToTime(1768) // 00:29:28
secondsToTime(3600) // 01:00:00
secondsToTime(5296) // 01:28:16
secondsToTime(7735) // 02:08:55
secondsToTime(45296) // 12:34:56
secondsToTime(145296) // 40:21:36
secondsToTime(1145296) // 318:08:16
*/
2019 best variant
Format hh:mm:ss
console.log(display(60 * 60 * 2.5 + 25)) // 2.5 hours + 25 seconds
function display (seconds) {
const format = val => `0${Math.floor(val)}`.slice(-2)
const hours = seconds / 3600
const minutes = (seconds % 3600) / 60
return [hours, minutes, seconds % 60].map(format).join(':')
}
You can also use native Date object:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
Of course this solution works only for timeInSeconds less than 24 hours ;)
function secondsToMinutes(time){
return Math.floor(time / 60)+':'+Math.floor(time % 60);
}
To add leading zeros, I would just do:
const secondsToMinSecPadded = time => {
const minutes = "0" + Math.floor(time / 60);
const seconds = "0" + (time - minutes * 60);
return minutes.substr(-2) + ":" + seconds.substr(-2);
};
console.log(secondsToMinSecPadded(241));
Nice and short
Moment.js
If you are using Moment.js then you can use there built in Duration object
const duration = moment.duration(4825, 'seconds');
const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25
Clean one liner using ES6
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
The most concise method I found can be done using in just one line:
let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`
Explanation
`${...}`Template literals. Allows for expressions to be converted into a string from within the string itself.Note: Incompatible with IE.
timeInSeconds/60|0Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)
timeInSeconds%60Remainder (modulo). Gives the remainder of the variable divided by 60.
Hours
This method can be expanded to include hours like this:
let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`
Repeating this process, you can even include days.
A one liner (doesnt work with hours):
function sectostr(time) {
return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
}
Seconds to h:mm:ss
var hours = Math.floor(time / 3600);
time -= hours * 3600;
var minutes = Math.floor(time / 60);
time -= minutes * 60;
var seconds = parseInt(time % 60, 10);
console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));
The Following function will help you to get Days , Hours , Minutes , seconds
toDDHHMMSS(inputSeconds){
const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
let ddhhmmss = '';
if (Days > 0){
ddhhmmss += Days + ' Day ';
}
if (Hour > 0){
ddhhmmss += Hour + ' Hour ';
}
if (Minutes > 0){
ddhhmmss += Minutes + ' Minutes ';
}
if (Seconds > 0){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}
alert( toDDHHMMSS(2000));
After all this, yet another simple solution:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());
Another but much more elegant solution for this is as follows:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* #param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};
function formatSeconds(s: number) {
let minutes = ~~(s / 60);
let seconds = ~~(s % 60);
return minutes + ':' + seconds;
}
For adding zeros I really don't see the need to have a full other function where you can simply use for example
var mins=Math.floor(StrTime/60);
var secs=StrTime-mins * 60;
var hrs=Math.floor(StrTime / 3600);
RoundTime.innerHTML=(hrs>9?hrs:"0"+hrs) + ":" + (mins>9?mins:"0"+mins) + ":" + (secs>9?secs:"0"+secs);
Its why we have conditional statements in the first place.
(condition?if true:if false) so if example seconds is more than 9 than just show seconds else add a string 0 before it.
var seconds = 60;
var measuredTime = new Date(null);
measuredTime.setSeconds(seconds); // specify value of SECONDS
var Time = measuredTime.toISOString().substr(11, 8);
document.getElementById("id1").value = Time;
<div class="form-group">
<label for="course" class="col-md-4">Time</label>
<div class="col-md-8">
<input type="text" class="form-control" id="id1" name="field">Min
</div>
</div>
Try this:
Converting Second to HOURS, MIN and SEC.
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}
1 - Get rest of division using %. Now you have the seconds that don't complete a minute
2 - Subtract the seconds obtained in step 1 from the total. Now you have the minutes
For example, let's assume you have 700 seconds:
seconds = 700%60); //40 seconds
minutes = (700 - (700%60))/60; //11
//11:40
I was thinking of a faster way to get this done and this is what i came up with
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
If we want to convert "time" to minutes and seconds, for example:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
Put my two cents in :
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
So this :
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
Will have the following output :
[1,41];
Then you can print it like so :
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
export function TrainingTime(props) {
const {train_time } = props;
const hours = Math.floor(train_time/3600);
const minutes = Math.floor((train_time-hours * 3600) / 60);
const seconds = Math.floor((train_time%60));
return `${hours} hrs ${minutes} min ${seconds} sec`;
}
Day.js
If you use day.js, try this.
const dayjs = require('dayjs')
const duration = require('dayjs/plugin/duration')
dayjs.extend(duration)
const time = dayjs.duration(100, 'seconds')
time.seconds() // 40
time.minutes() // 1
time.format('mm:ss') // 01:40
I prefer thinking of Millisecond as its own unit, rather than as a subunit of something else. In that sense, it will have values of 0-999, so you're going to want to Pad three instead of two like I have seen with other answers. Here is an implementation:
function format(n) {
let mil_s = String(n % 1000).padStart(3, '0');
n = Math.trunc(n / 1000);
let sec_s = String(n % 60).padStart(2, '0');
n = Math.trunc(n / 60);
return String(n) + ' m ' + sec_s + ' s ' + mil_s + ' ms';
}
console.log(format(241));
https://developer.mozilla.org/Web/JavaScript/Reference/Global_Objects/String/padStart
Here's an ES6 version of the seconds to minutes and seconds conversion, with padding (00:00 format). It only accepts integer values for seconds and ~~(x) is the shorthand floor operation.
const padTime = n => ("" + n).padStart(2, 0);
const secondsToMinSec = time =>
`${padTime(~~(time / 60))}:${padTime(time - ~~(time / 60) * 60)}`
;
for (let i = 0; i < 10; i++) {
const seconds = ~~(Math.random() * 300);
console.log(seconds, secondsToMinSec(seconds));
}
if you need to work with the result easily later this is what I use:
function seconds2hms(seconds, milliseconds) {
if(milliseconds) {
seconds = Math.floor(seconds/1000);
}
return {h:~~(seconds / 3600),m:~~((seconds % 3600) / 60),s:~~seconds % 60}
}
(used Vishal's code)
strftime.js (strftime github) is one of the best time formatting libraries. It's extremely light - 30KB - and effective. Using it you can convert seconds into time easily in one line of code, relying mostly on the native Date class.
When creating a new Date, each optional argument is positional as follows:
new Date(year, month, day, hours, minutes, seconds, milliseconds);
So if you initialize a new Date with all arguments as zero up to the seconds, you'll get:
var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)
You can see that 150 seconds is 2-minutes and 30-seconds, as seen in the date created. Then using an strftime format ("%M:%S" for "MM:SS"), it will output your minutes' string.
var mm_ss_str = strftime("%M:%S", date);
=> "02:30"
In one line, it would look like:
var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"
Plus this would allow you to interchangeable support HH:MM:SS and MM:SS based on the number of seconds. For example:
# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"
# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"
And of course, you can simply pass whatever format you want to strftime if you want the time string to be more or less semantic.
var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"
You've done enough code to track minutes and seconds portions of time.
What you could do is add the hours factor in:
var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);
var mind = hrd % 60;
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
var moreminutes = minutes + hours * 60
This is a common problem but I'm not sure how to solve it. The code below works fine.
var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
However, when I get to 1 hour or 3600 seconds it returns 0 minutes and 0 seconds. How can I avoid this so it returns all the minutes?
To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):
const minutes = Math.floor(time / 60);
And to get the remaining seconds, multiply the full minutes with 60 and subtract from the total seconds:
const seconds = time - minutes * 60;
Now if you also want to get the full hours too, divide the number of total seconds by 3600 (60 minutes/hour · 60 seconds/minute) first, then calculate the remaining seconds:
const hours = Math.floor(time / 3600);
time = time - hours * 3600;
Then you calculate the full minutes and remaining seconds.
Bonus:
Use the following code to pretty-print the time (suggested by Dru):
function str_pad_left(string, pad, length) {
return (new Array(length + 1).join(pad) + string).slice(-length);
}
const finalTime = str_pad_left(minutes, '0', 2) + ':' + str_pad_left(seconds, '0', 2);
Another fancy solution:
function fancyTimeFormat(duration) {
// Hours, minutes and seconds
const hrs = ~~(duration / 3600);
const mins = ~~((duration % 3600) / 60);
const secs = ~~duration % 60;
// Output like "1:01" or "4:03:59" or "123:03:59"
let ret = "";
if (hrs > 0) {
ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
}
ret += "" + mins + ":" + (secs < 10 ? "0" : "");
ret += "" + secs;
return ret;
}
console.log(
fancyTimeFormat(1),
fancyTimeFormat(10),
fancyTimeFormat(100),
fancyTimeFormat(1000),
fancyTimeFormat(10000),
);

For people dropping in hoping for a quick simple and thus short solution to format seconds into M:SS :
function fmtMSS(s){return(s-(s%=60))/60+(9<s?':':':0')+s}
done..
The function accepts either a Number (preferred) or a String (2 conversion 'penalties' which you can halve by prepending + in the function call's argument for s as in: fmtMSS(+strSeconds)), representing positive integer seconds s as argument.
Examples:
fmtMSS( 0 ); // 0:00
fmtMSS( '8'); // 0:08
fmtMSS( 9 ); // 0:09
fmtMSS( '10'); // 0:10
fmtMSS( 59 ); // 0:59
fmtMSS( +'60'); // 1:00
fmtMSS( 69 ); // 1:09
fmtMSS( 3599 ); // 59:59
fmtMSS('3600'); // 60:00
fmtMSS('3661'); // 61:01
fmtMSS( 7425 ); // 123:45
Breakdown:
function fmtMSS(s){ // accepts seconds as Number or String. Returns m:ss
return( s - // take value s and subtract (will try to convert String to Number)
( s %= 60 ) // the new value of s, now holding the remainder of s divided by 60
// (will also try to convert String to Number)
) / 60 + ( // and divide the resulting Number by 60
// (can never result in a fractional value = no need for rounding)
// to which we concatenate a String (converts the Number to String)
// who's reference is chosen by the conditional operator:
9 < s // if seconds is larger than 9
? ':' // then we don't need to prepend a zero
: ':0' // else we do need to prepend a zero
) + s ; // and we add Number s to the string (converting it to String as well)
}
Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).

MINUTES => 535 / 60 = 8 remainder 55
SECONDS => 55
LEADING ZEROS:
Many answers here use complicated methods to show number of hours, minutes and seconds in a proper way with leading zero - 45, 04 etc. This can be done using padStart(). This works for strings so the number must be converted to string using toString().
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart
The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.
CODE:
function secondsToTime(e){
const h = Math.floor(e / 3600).toString().padStart(2,'0'),
m = Math.floor(e % 3600 / 60).toString().padStart(2,'0'),
s = Math.floor(e % 60).toString().padStart(2,'0');
return h + ':' + m + ':' + s;
//return `${h}:${m}:${s}`;
}
console.log(secondsToTime(7735)); // 02:08:55
/*
secondsToTime(SECONDS) // HH:MM:SS
secondsToTime(8) // 00:00:08
secondsToTime(68) // 00:01:08
secondsToTime(1768) // 00:29:28
secondsToTime(3600) // 01:00:00
secondsToTime(5296) // 01:28:16
secondsToTime(7735) // 02:08:55
secondsToTime(45296) // 12:34:56
secondsToTime(145296) // 40:21:36
secondsToTime(1145296) // 318:08:16
*/

Format hh:mm:ss
console.log(display(60 * 60 * 2.5 + 25)) // 2.5 hours + 25 seconds
function display (seconds) {
const format = val => `0${Math.floor(val)}`.slice(-2)
const hours = seconds / 3600
const minutes = (seconds % 3600) / 60
return [hours, minutes, seconds % 60].map(format).join(':')
}
You can also use native Date object:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
Of course this solution works only for timeInSeconds less than 24 hours ;)
function secondsToMinutes(time){
return Math.floor(time / 60)+':'+Math.floor(time % 60);
}
To add leading zeros, I would just do:
const secondsToMinSecPadded = time => {
const minutes = "0" + Math.floor(time / 60);
const seconds = "0" + (time - minutes * 60);
return minutes.substr(-2) + ":" + seconds.substr(-2);
};
console.log(secondsToMinSecPadded(241));
Nice and short
Moment.js
If you are using Moment.js then you can use there built in Duration object
const duration = moment.duration(4825, 'seconds');
const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25
Clean one liner using ES6
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
The most concise method I found can be done using in just one line:
let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`
Explanation
`${...}`Template literals. Allows for expressions to be converted into a string from within the string itself.Note: Incompatible with IE.
timeInSeconds/60|0Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)
timeInSeconds%60Remainder (modulo). Gives the remainder of the variable divided by 60.
Hours
This method can be expanded to include hours like this:
let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`
Repeating this process, you can even include days.
A one liner (doesnt work with hours):
function sectostr(time) {
return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
}
Seconds to h:mm:ss
var hours = Math.floor(time / 3600);
time -= hours * 3600;
var minutes = Math.floor(time / 60);
time -= minutes * 60;
var seconds = parseInt(time % 60, 10);
console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));
The Following function will help you to get Days , Hours , Minutes , seconds
toDDHHMMSS(inputSeconds){
const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
let ddhhmmss = '';
if (Days > 0){
ddhhmmss += Days + ' Day ';
}
if (Hour > 0){
ddhhmmss += Hour + ' Hour ';
}
if (Minutes > 0){
ddhhmmss += Minutes + ' Minutes ';
}
if (Seconds > 0){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}
alert( toDDHHMMSS(2000));
After all this, yet another simple solution:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());
Another but much more elegant solution for this is as follows:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* #param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};
function formatSeconds(s: number) {
let minutes = ~~(s / 60);
let seconds = ~~(s % 60);
return minutes + ':' + seconds;
}
For adding zeros I really don't see the need to have a full other function where you can simply use for example
var mins=Math.floor(StrTime/60);
var secs=StrTime-mins * 60;
var hrs=Math.floor(StrTime / 3600);
RoundTime.innerHTML=(hrs>9?hrs:"0"+hrs) + ":" + (mins>9?mins:"0"+mins) + ":" + (secs>9?secs:"0"+secs);
Its why we have conditional statements in the first place.
(condition?if true:if false) so if example seconds is more than 9 than just show seconds else add a string 0 before it.
var seconds = 60;
var measuredTime = new Date(null);
measuredTime.setSeconds(seconds); // specify value of SECONDS
var Time = measuredTime.toISOString().substr(11, 8);
document.getElementById("id1").value = Time;
<div class="form-group">
<label for="course" class="col-md-4">Time</label>
<div class="col-md-8">
<input type="text" class="form-control" id="id1" name="field">Min
</div>
</div>
Try this:
Converting Second to HOURS, MIN and SEC.
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}
1 - Get rest of division using %. Now you have the seconds that don't complete a minute
2 - Subtract the seconds obtained in step 1 from the total. Now you have the minutes
For example, let's assume you have 700 seconds:
seconds = 700%60); //40 seconds
minutes = (700 - (700%60))/60; //11
//11:40
I was thinking of a faster way to get this done and this is what i came up with
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
If we want to convert "time" to minutes and seconds, for example:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
Put my two cents in :
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
So this :
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
Will have the following output :
[1,41];
Then you can print it like so :
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
export function TrainingTime(props) {
const {train_time } = props;
const hours = Math.floor(train_time/3600);
const minutes = Math.floor((train_time-hours * 3600) / 60);
const seconds = Math.floor((train_time%60));
return `${hours} hrs ${minutes} min ${seconds} sec`;
}
Day.js
If you use day.js, try this.
const dayjs = require('dayjs')
const duration = require('dayjs/plugin/duration')
dayjs.extend(duration)
const time = dayjs.duration(100, 'seconds')
time.seconds() // 40
time.minutes() // 1
time.format('mm:ss') // 01:40
I prefer thinking of Millisecond as its own unit, rather than as a subunit of something else. In that sense, it will have values of 0-999, so you're going to want to Pad three instead of two like I have seen with other answers. Here is an implementation:
function format(n) {
let mil_s = String(n % 1000).padStart(3, '0');
n = Math.trunc(n / 1000);
let sec_s = String(n % 60).padStart(2, '0');
n = Math.trunc(n / 60);
return String(n) + ' m ' + sec_s + ' s ' + mil_s + ' ms';
}
console.log(format(241));
https://developer.mozilla.org/Web/JavaScript/Reference/Global_Objects/String/padStart
Here's an ES6 version of the seconds to minutes and seconds conversion, with padding (00:00 format). It only accepts integer values for seconds and ~~(x) is the shorthand floor operation.
const padTime = n => ("" + n).padStart(2, 0);
const secondsToMinSec = time =>
`${padTime(~~(time / 60))}:${padTime(time - ~~(time / 60) * 60)}`
;
for (let i = 0; i < 10; i++) {
const seconds = ~~(Math.random() * 300);
console.log(seconds, secondsToMinSec(seconds));
}
if you need to work with the result easily later this is what I use:
function seconds2hms(seconds, milliseconds) {
if(milliseconds) {
seconds = Math.floor(seconds/1000);
}
return {h:~~(seconds / 3600),m:~~((seconds % 3600) / 60),s:~~seconds % 60}
}
(used Vishal's code)
strftime.js (strftime github) is one of the best time formatting libraries. It's extremely light - 30KB - and effective. Using it you can convert seconds into time easily in one line of code, relying mostly on the native Date class.
When creating a new Date, each optional argument is positional as follows:
new Date(year, month, day, hours, minutes, seconds, milliseconds);
So if you initialize a new Date with all arguments as zero up to the seconds, you'll get:
var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)
You can see that 150 seconds is 2-minutes and 30-seconds, as seen in the date created. Then using an strftime format ("%M:%S" for "MM:SS"), it will output your minutes' string.
var mm_ss_str = strftime("%M:%S", date);
=> "02:30"
In one line, it would look like:
var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"
Plus this would allow you to interchangeable support HH:MM:SS and MM:SS based on the number of seconds. For example:
# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"
# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"
And of course, you can simply pass whatever format you want to strftime if you want the time string to be more or less semantic.
var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"
You've done enough code to track minutes and seconds portions of time.
What you could do is add the hours factor in:
var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);
var mind = hrd % 60;
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
var moreminutes = minutes + hours * 60
While trying to convert seconds into HH:MM:SS seconds format, I am getting the incorrect result. For example, if take value of seconds be 289 the minutes come out as 0. What could be the reason for this
var seconds = this.currentTime;
var hours = Math.floor(seconds/3600); // Get whole hours
seconds -= hours*3600;
var minutes = Math.floor(seconds/3600); // Get remaining minutes
console.log("minutes : " + minutes);
seconds -= minutes*60;
var timeNow = hours + ":" + (minutes<10 ? '0'+minutes : minutes) + ":" + (seconds<10 ? '0'+seconds : seconds);
To calculate minutes, you should divide seconds by 60, not 3600 (there are 60 seconds in a minute after all):
var minutes = Math.floor(seconds/60); // Get remaining minutes
You could also use the Date object in JavaScript to do most of this for you:
var date = new Date(0, 0, 0, 0, 0, 289, 0);
var minutes = date.getMinutes();
// etc.
var timeInSec = this.currentTime;
var hours = Math.floor(timeInSec / 3600) % 24; // Get whole hours
var minutes = Math.floor(timeInSec / 60) % 60; // Get remaining minutes
var seconds = timeInSec % 60; // Get remaining seconds
var timeNow = (hours < 10 ? "0" + hours : hours) + "-" + (minutes < 10 ? "0" + minutes : minutes) + "-" + (seconds < 10 ? "0" + seconds : seconds);
In JavaScript I have a variable Time in milliseconds.
I would like to know if there is any build-in function to convert efficiently this value to Minutes:Seconds format.
If not could you please point me out a utility function.
Example:
FROM
462000 milliseconds
TO
7:42
Just create a Date object and pass the milliseconds as a parameter.
var date = new Date(milliseconds);
var h = date.getHours();
var m = date.getMinutes();
var s = date.getSeconds();
alert(((h * 60) + m) + ":" + s);
Thanks guys for your support, at th end I came up with this solution. I hope it can helps others.
Use:
var videoDuration = convertMillisecondsToDigitalClock(18050200).clock; // CONVERT DATE TO DIGITAL FORMAT
// CONVERT MILLISECONDS TO DIGITAL CLOCK FORMAT
function convertMillisecondsToDigitalClock(ms) {
hours = Math.floor(ms / 3600000), // 1 Hour = 36000 Milliseconds
minutes = Math.floor((ms % 3600000) / 60000), // 1 Minutes = 60000 Milliseconds
seconds = Math.floor(((ms % 360000) % 60000) / 1000) // 1 Second = 1000 Milliseconds
return {
hours : hours,
minutes : minutes,
seconds : seconds,
clock : hours + ":" + minutes + ":" + seconds
};
}
In case you already using Moment.js in your project, you can use the moment.duration function
You can use it like this
var mm = moment.duration(37250000);
console.log(mm.hours() + ':' + mm.minutes() + ':' + mm.seconds());
output: 10:20:50
See jsbin sample
It's easy to make the conversion oneself:
var t = 462000
parseInt(t / 1000 / 60) + ":" + (t / 1000 % 60)
You may like pretty-ms npm package: https://www.npmjs.com/package/pretty-ms
If that what you are searching. Headless nice formatting (time in the units that are needed as ms grow), personalisable, and cover different situations. Small and efficient for what it cover.

var M = Math.floor(ms / 60000);
ms -= M * 60000;
var S = ms / 1000;
return M + ":" + S;
