Convert dd-mm-yyyy string to date

How to convert a date in format 23/10/2015 into a
JavaScript Date format:
Fri Oct 23 2015 15:24:53 GMT+0530 (India Standard Time)
MM/DD/YYYY format
If you have the MM/DD/YYYY format which is default for JavaScript, you can simply pass your string to Date(string) constructor. It will parse it for you.
var dateString = "10/23/2015"; // Oct 23
var dateObject = new Date(dateString);
document.body.innerHTML = dateObject.toString();
DD/MM/YYYY format - manually
If you work with this format, then you can split the date in order to get day, month and year separately and then use it in another constructor - Date(year, month, day):
var dateString = "23/10/2015"; // Oct 23
var dateParts = dateString.split("/");
// month is 0-based, that's why we need dataParts[1] - 1
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]);
document.body.innerHTML = dateObject.toString();
For more information, you can read article about Date at Mozilla Developer Network.
DD/MM/YYYY - using moment.js library
Alternatively, you can use moment.js library, which is probably the most popular library to parse and operate with date and time in JavaScript:
var dateString = "23/10/2015"; // Oct 23
var dateMomentObject = moment(dateString, "DD/MM/YYYY"); // 1st argument - string, 2nd argument - format
var dateObject = dateMomentObject.toDate(); // convert moment.js object to Date object
document.body.innerHTML = dateObject.toString();
<script src="https://momentjs.com/downloads/moment.min.js"></script>
In all three examples dateObject variable contains an object of type Date, which represents a moment in time and can be further converted to any string format.
Here's one I prepared earlier...
convertToDate(dateString) {
// Convert a "dd/MM/yyyy" string into a Date object
let d = dateString.split("/");
let dat = new Date(d[2] + '/' + d[1] + '/' + d[0]);
return dat;
}
var dateString = "23/10/2015"; // Oct 23
var newData = dateString.replace(/(\d+[/])(\d+[/])/, '$2$1');
var data = new Date(newData);
document.body.innerHTML = date.toString();ere
While most responses were tied to splitting strings or using native date methods, the two closely-related ones using RegEx (i.e., answer by [drgol] and comment by [Tomás Hugo Almeida]) are both instructive about the use of capturing groups. Their succinctness also helps illustrate the value of capturing and distinguishing that from matching - two related concepts that can confuse new RegEx users. This code block consolidates their 2 answers but see originals above: const origDate = '23/07/2020'; const newDate = origDate.replace(/(\d+[/])(\d+[/])/, '$2$1'); // newDate = '07/23/2020';
I found the default JS date formatting didn't work.
So I used toLocaleString with options
const event = new Date();
const options = { dateStyle: 'short' };
const date = event.toLocaleString('en', options);
to get: DD/MM/YYYY format
See docs for more formatting options: https://www.w3schools.com/jsref/jsref_tolocalestring.asp
Parsing a string to create another string that is then parsed by the built–in parser is not an efficient strategy, particularly when neither string is in a format supported by ECMA-262.
A more efficient strategy is to parse the string once and give the parts directly to the constructor, avoiding the second parse, e.g.
const parseDMY = s => {
let [d, m, y] = s.split(/\D/);
return new Date(y, m-1, d);
};
console.log(parseDMY('23/10/2015').toString());
Date.parse only supports the formats produced by:
Date.protoype.toString
Date.protoype.toISOString
Date.protoype.toUTCString
Parsing of any other format (including m/d/y) is implementation dependent.
Here is a way to transform a date string with a time of day to a date object. For example to convert "20/10/2020 18:11:25" ("DD/MM/YYYY HH:MI:SS" format) to a date object
function newUYDate(pDate) {
let dd = pDate.split("/")[0].padStart(2, "0");
let mm = pDate.split("/")[1].padStart(2, "0");
let yyyy = pDate.split("/")[2].split(" ")[0];
let hh = pDate.split("/")[2].split(" ")[1].split(":")[0].padStart(2, "0");
let mi = pDate.split("/")[2].split(" ")[1].split(":")[1].padStart(2, "0");
let secs = pDate.split("/")[2].split(" ")[1].split(":")[2].padStart(2, "0");
mm = (parseInt(mm) - 1).toString(); // January is 0
return new Date(yyyy, mm, dd, hh, mi, secs);
}
you can use this short function
// dateString: "15/06/2021"
const stringToDate = (dateString) => {
const [day, month, year] = dateString.split('/');
return new Date([month, day, year].join('/'));
};
document.body.innerHTML = stringToDate("15/06/2021").toString();
var date = new Date("enter your date");//2018-01-17 14:58:29.013
Just one line is enough no need to do any kind of split, join, etc.:
$scope.ssdate=date.toLocaleDateString();// mm/dd/yyyy format
<!DOCTYPE html>
<script>
dateString = "23/10/2015"; //23 Oct 2015
d = dateString.split("/");
x = d[1] + "/" + d[0] + "/" + d[2]; //"10/23/2015"
y = d[2] + "/" + d[1] + "/" + d[0]; //"2015/10/23"
alert(
new Date(x) + "\n\n" +
new Date(y) + "\n\n" +
new Date(dateString) + "\n" +
"");
</script>

Convert a Unix timestamp to time in JavaScript

How do I format a date in JavaScript?
(68 answers)
Closed last year.
How to convert this timestamp 1382086394000 to 2013-10-18 08:53:14 using a function in javascript? Currently I have this function:
function cleanDate(d) {return new Date(+d.replace(/\/Date\((\d+)\)\//, '$1'));}
The value 1382086394000 is probably a time value, which is the number of milliseconds since 1970-01-01T00:00:00Z. You can use it to create an ECMAScript Date object using the Date constructor:
var d = new Date(1382086394000);
How you convert that into something readable is up to you. Simply sending it to output should call the internal (and entirely implementation dependent) toString method* that usually prints the equivalent system time in a human readable form, e.g.
Fri Oct 18 2013 18:53:14 GMT+1000 (EST)
In ES5 there are some other built-in formatting options:
toDateString
toTimeString
toLocaleString
and so on. Note that most are implementation dependent and will be different in different browsers. If you want the same format across all browsers, you'll need to format the date yourself, e.g.:
alert(d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear());
* The format of Date.prototype.toString has been standardised in ECMAScript 2018. It might be a while before it's ubiquitous across all implementations, but at least the more common browsers support it now.
This works fine. Checked in chrome browser:
var theDate = new Date(timeStamp_value * 1000);
dateString = theDate.toGMTString();
alert(dateString );
why not simply
new Date (timestamp);
A date is a date, the formatting of it is a different matter.
Moment.js can convert unix timestamps into any custom format
In this case : var time = moment(1382086394000).format("DD-MM-YYYY h:mm:ss");
will print 18-10-2013 11:53:14;
Here's a plunker that demonstrates this.
Here are the simple ways to every date format confusions:
for current date:
var current_date=new Date();
to get the Timestamp of current date:
var timestamp=new Date().getTime();
to convert a particular Date into Timestamp:
var timestamp_formation=new Date('mm/dd/yyyy').getTime();
to convert timestamp into Date:
var timestamp=new Date('02/10/2016').getTime();
var todate=new Date(timestamp).getDate();
var tomonth=new Date(timestamp).getMonth()+1;
var toyear=new Date(timestamp).getFullYear();
var original_date=tomonth+'/'+todate+'/'+toyear;
OUTPUT:
02/10/2016
we need to create new function using JavaScript.
function unixTime(unixtime) {
var u = new Date(unixtime*1000);
return u.getUTCFullYear() +
'-' + ('0' + u.getUTCMonth()).slice(-2) +
'-' + ('0' + u.getUTCDate()).slice(-2) +
' ' + ('0' + u.getUTCHours()).slice(-2) +
':' + ('0' + u.getUTCMinutes()).slice(-2) +
':' + ('0' + u.getUTCSeconds()).slice(-2) +
'.' + (u.getUTCMilliseconds() / 1000).toFixed(3).slice(2, 5)
};
console.log(unixTime(1370001284))

This is what I did for the Instagram API. converted timestamp with date method by multiplying by 1000.
and then added all entity individually like (year, months, etc)
created the custom month list name and mapped it with getMonth() method which returns the index of the month.
convertStampDate(unixtimestamp){
// Months array
var months_arr = ['January','February','March','April','May','June','July','August','September','October','November','December'];
// Convert timestamp to milliseconds
var date = new Date(unixtimestamp*1000);
// Year
var year = date.getFullYear();
// Month
var month = months_arr[date.getMonth()];
// Day
var day = date.getDate();
// Hours
var hours = date.getHours();
// Minutes
var minutes = "0" + date.getMinutes();
// Seconds
var seconds = "0" + date.getSeconds();
// Display date time in MM-dd-yyyy h:m:s format
var fulldate = month+' '+day+'-'+year+' '+hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);
// final date
var convdataTime = month+' '+day;
return convdataTime;
}
Call with stamp argument
convertStampDate('1382086394000')
and that's it.
Use .toLocaleString:
// undefined uses default locale
console.log(new Date().toLocaleString(undefined, {dateStyle: 'short'}));
Or custom method in case you don't want to use the toLocaleString for some reason:
formatDate is the function you can call it and pass the date you want to format to dd/mm/yyyy
var unformatedDate = new Date("2017-08-10 18:30:00");
$("#hello").append(formatDate(unformatedDate));
function formatDate(nowDate) {
return nowDate.getDate() +"/"+ (nowDate.getMonth() + 1) + '/'+ nowDate.getFullYear();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hello">
</div>
My ES6 variant produces a string like this 2020-04-05_16:39:45.85725. Feel free to modify the return statement to get the format that you need:
const getDateStringServ = timestamp => {
const plus0 = num => `0${num.toString()}`.slice(-2)
const d = new Date(timestamp)
const year = d.getFullYear()
const monthTmp = d.getMonth() + 1
const month = plus0(monthTmp)
const date = plus0(d.getDate())
const hour = plus0(d.getHours())
const minute = plus0(d.getMinutes())
const second = plus0(d.getSeconds())
const rest = timestamp.toString().slice(-5)
return `${year}-${month}-${date}_${hour}:${minute}:${second}.${rest}`
}
There is a simple way to convert to a more readable form
new Date().toLocaleString();
new Date(1630734254000).toLocaleString();
Outputs in this format => 9/4/2021, 11:14:14 AM
new Date(timestamp).toString().substring(4, 15)
1631685556789 ==> Sep 15 2021

I am getting an input as in
23071996 being DDMMYYYY in date.
or
07231996 which is MMDDYYYY
Now I want to translate this input to a date to see if this date is valid or not.
From this question, I got how we can check if it is valid date or not but I am not sure how I can translate this to 23071996 or 07231996 to actual date
You can do this using substring().
Example:
var date = '23071996';
function convertDate(date) {
if(date.length !== 8) return 'Invalid Date'; // Checks if date is valid in terms of length
var day = date.substring(0, 2);
var month = date.substring(2, 4);
var year = date.substring(4, 8);
return { day: day, month: month, year: year };
}
var convertedDate = convertDate(date); // Converted date
function convertToDateObject(convertedDate) {
return new Date(convertedDate.year, convertedDate.month, convertedDate.day);
}
var trueDate = convertToDateObject(convertedDate); // Date as JavaScript object, this might be useful
Converting this to the American date format is relatively easy, you just swap the day and month. Accepting both formats would be quite difficult without getting input from the user on what format it is.
var _d = '07231996';
_d = _d.replace(/(\d{2})(\d{2})(\d{4})/, "$1-$2-$3");
document.write(new Date(_d));
Using Date() constructor and dateString format:
let str = '23071996';
date = new Date(str.slice(-4) + '-' + str.slice(2,4) + '-' + str.slice(0,2))
console.log(date)
I have a date at a string - dtStr
var dtStr = "Thu May 28 02:13:16 BDT 2015";
I want to get a date like - MM DD YYYY HH mm format from the dtStr. For getting this I am trying to convert the dtStr to a Date and then try to use date format like this -
var dtStr = "Thu May 28 02:13:16 BDT 2015";
today = new Date(dtStr);
alert( today.toLocalDateFormat("MM DD YYYY HH mm") );
But it didn't work for me. Can any one help me for - converting dtStr to a date with format MM DD YYYY HH mm ?
Thanks in advance.
Unfortunately, the string you're trying to parse won't be accepted by Date.parse(), the method that will parse the string when you're creating it. If the string will always be in that format, you could do some string manipulation and rearrange it to the RFC2822/IETF format, which Date() can handle.
// this creates a proper Date object
new Date("Thu, May 28 2015 02:13:16 +0600");
Alternatively, you could create a new Date object with one of the other constructors, by splitting/parsing the string yourself, and inserting them in the correct places in the constructor.
At this point, you'll have a Date object, but you still need to get the values from it - the only built in method that can do something like what you're trying to do is toLocaleFormat(), which isn't standard track (it's not supported in my version of Chrome, for example). Thus, you would need to get the values independently, and concatenate them together.
At this point, it's probably easier to just do straight up parsing of the string, and skip the Date object altogether, or use a library like datejs, which provides support for formatting output strings.
You may try to use the following method -
function formatReview(date){
/*****************************************************************
* The method parameter 'date' is in the following format -
* "Thu May 28 02:13:16 BDT 2015"
* Javascript 'new Date()' has not suitable constructor to
* support this format. The parameter 'date' need to
* convert to fee the Date() constructor.
*******************************************************************/
var monthSymbols = "JanFebMarAprMayJunJulAugSepOctNovDec";
var elements = date.split(" ");
var day = elements[0];
var monthName = elements[1];
var monthIndex = monthSymbols.indexOf(monthName)/3 +1;
var date = elements[2];
var year = elements[5];
var timestamp = elements[3];
var timestampElements = timestamp.split(":");
var hour = timestampElements[0];
var minutes = timestampElements[1];
var dateString = monthIndex +"-"+ date +"-"+ year +" "+ hour +":"+ minutes;
return dateString;
}
Try this
var todayDate=new Date("Thu May 29 2014 13:50:00");
var format ="AM";
var hour=todayDate.getHours();
var min=todayDate.getMinutes();
if(hour>11){format="PM";}
if (hour > 12) { hour = hour - 12; }
if (hour == 0) { hour = 12; }
if (min < 10){min = "0" + min;}
document.write(todayDate.getMonth()+1 + " / " + todayDate.getDate() + " / " + todayDate.getFullYear()+" "+hour+":"+min+" ");

The timestamp I get from a server's SOAP response is formatted in European Notation and in GMT time (ex: 08/07/2010 11:22:00 AM). I want to convert it to local time and change the formatting to (MM/DD/2010 HH:MM:SS AM/PM).
I know about the JavaScript Date object but can't figure out the logic of how to do the conversion. Can anyone help me?
Do you really need date objects for this? If all you're doing is switching the first two parts of a string of that exact format,
var pieces = str.split('/');
str = pieces[1] + '/' + pieces[0] + '/' + pieces[2];
Parse dates using:
Date.parse("08/07/2010 11:22:00 AM");
To convert the GMT date to local date (one on the browser or js useragent) use the following function:
function getLocalTime(gmt) {
var min = gmt.getTime() / 1000 / 60; // convert gmt date to minutes
var localNow = new Date().getTimezoneOffset(); // get the timezone
// offset in minutes
var localTime = min - localNow; // get the local time
return new Date(localTime * 1000 * 60); // convert it into a date
}
var dt = new Date(Date.parse("08/07/2010 11:22:00 AM"));
var localDate = getLocalTime(dt);
Next is date formatting, which is quite simple. Call the following functions on your newly obtained (local) date:
localDate.getXXX(); // where XXX is Hour, Minutes, etc.
Note: Tested in FF. Tweak as required in other browsers :)
I know this is a year old and has an accepted answer. Just in case someone comes around looking...
You can append the timezone information to the formatted string and create a date object to get what you want.
var x = "08/07/2010 11:22:00 AM".split('/');
var d = new Date(x[1] + '/' + x[0] + '/' + x[2] + " GMT");
jsfiddle
Just to make sure I understand what you wanted, I ran the accpeted answer along with this, both return the same result.
function switchFormat(dateString) {
var a = dateString.split('/'),
b;
b = a[0];
a[0] = a[1];
a[1] = b;
return a.join('/');
}
Edited
Try it here
var serverTimestamp = storArray[a][0];
var pieces = serverTimestamp.split('/');
storArray[a][0] = pieces[1] + '/' + pieces[0] + '/' + pieces[2];
var gmt = new Date(storArray[a][0]);
var localTime = gmt.getTime() - (gmt.getTimezoneOffset() * 60000); // convert gmt date to minutes
var localDate = new Date(localTime); // convert it into a date
Step 1 you are getting date from input type date like below
like 2021-08-18 as string
then
var formatted date = date.split('-')[2]+"/"+date.split('-')1+"/"+date.split('-')[0])
result will be 18/08/2021
