At the moment i have this JS which after 2pm it says 'Expired' but i no longer want that and wasnt sure how to just reset the timer and make it start counting towards tomorrows 2pm
var d = new Date();
var local_date = new Date( Date.UTC( d.getFullYear(), d.getMonth(), d.getDate(), 14,0) );
var now = new Date().getTime();
var distance = local_date - now;
Change your codes as given above.
set your local_date variable with local date and time.
local_date is also a time.
You may also ignore UTC as per your requirements.

looking for help with a countdown timer I have to reveal a container the page at a specific time. I'd like the "days" "hours" "minutes" to disappear when they reach zero.
Can anyone help?

You repeat some of the time calculations every second, better use some const instead:
const eCountDown = document.querySelector('.countdown')
, one_Sec = 1000
, one_Min = one_Sec * 60
, one_Hour = one_Min * 60
, one_Day = one_Hour * 24
;
var countDownDate = new Date(eCountDown.dateTime).getTime()
;
function ctd()
{
let now = new Date().getTime()
, distance = countDownDate - now
, days = Math.floor(distance / one_Day)
, hours = Math.floor((distance % one_Day) / one_Hour)
, minutes = Math.floor((distance % one_Hour) / one_Min)
, seconds = Math.floor((distance % one_Min) / one_Sec)
;
eCountDown.textContent = days + 'd '
+ hours + 'h '
+ minutes + 'm '
+ seconds + 's '
;
if (distance < 0)
{
clearInterval(timerIntv)
countdown.textContent = 'Item expired!'
}
}
ctd()
var timerIntv = setInterval(ctd, 1000)
<time class="countdown" datetime="2020-11-22T16:20:22+00:00"></time>
You need to use .countdown to get a class. You were missing the dot (.)
Also you should use attr or prop and not data. You can use data if you change your html property to data-datetime.
When in doubt, always console.log(countDownDate) to see what you get first.
var countDownDate = new Date($(".countdown").attr("datetime"));
function ctd() {
var now = new Date().getTime();
var distance = countDownDate - now;
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
countdown = document.getElementsByClassName("countdown");
countdown[0].innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
if (distance < 0) {
clearInterval(x);
countdown.innerHTML = "Item expired!";
}
}
ctd();
var x = setInterval(ctd, 1000);

I'm trying to convert the 0 in stock text on my website (held within a <p> tag) to a countdown timer, once the stock level hits 0. So I've added this code to the footer - however it seems to just stick, and not count down at all. It also takes a few seconds to replace the 0 in stock text - can I make this quicker/instant? Here's the code so far:
// Set the count down date
var countDownDate = new Date("Feb 21, 2021 15:26:00").getTime();
// Update the count every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Display the result if stock = 0
list = document.getElementsByClassName("stock in-stock");
if (list[0].innerHTML == "0 in stock") {
list[0].innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}
// If the count down is finished, write text
if (distance < 0) {
clearInterval(x);
list = document.getElementsByClassName("stock in-stock");
list[0].innerHTML = "Item expired!";
}
}, 1000);
<p class="stock in-stock">1 in stock</p>
You were trying to populate the P with new data and somehow trying to read out the old data, I've just separated that into 2 spans so you can work with each one individually and updated your JS to reflect the new structure.
To speed up the first call, extract the function:
Please note that we're treating "stock" and "countdown" as 2 different things now.
// Set the count down date
var countDownDate = new Date("Feb 21, 2021 15:26:00").getTime();
function ctd() {
// Get today's date and time
var now = new Date().getTime();
// Distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
//console.log(days + " " + hours + " " + minutes + " " + seconds);
// Display the result if stock = 0
countdown = document.getElementsByClassName("countdown");
stock = document.getElementsByClassName("stock-level");
if (stock[0].innerHTML == "1") {
countdown[0].innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}
// If the count down is finished, write text
if (distance < 0) {
clearInterval(x);
countdown.innerHTML = "Item expired!";
}
}
ctd(); // run now
// Update the count every 1 second
var x = setInterval(ctd, 1000);
<p class="stock-level" style="display:none">1</p>
<p class="countdown"></p>
I got it to work. Here's the code:
<script>
//Set the count down date
var countDownDate = new Date("Feb 20, 2019 18:26:00").getTime();
var startTimer=false;
list = document.getElementsByClassName("stock in-stock");
if(list[0].innerHTML=='1 in stock') {
startTimer=true;
}
//Check if 1 left
list = document.getElementsByClassName("stock in-stock");
//Update the count every 1 second
var x = setInterval(function() {
//Get today's date and time
var now = new Date().getTime();
//Distance between now and the count down date
var distance = countDownDate - now;
//Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
//Update the counter
if(startTimer) {
list[0].innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}
//If the count down is finished, write text
if (distance < 0) {
clearInterval(x);
list = document.getElementsByClassName("stock in-stock");
list[0].innerHTML = "Item expired!";
}
}, 1000);

I'm using the following JavaScript for a countdown timer and it has been working great in most browsers, I've just double checked Internet Explorer however and I am getting 'NaN' displayed in place of each number.
Can anyone help to explain where this goes wrong in IE not seeing the individual variables as a number?
// Set the date we're counting down to
var countDownDate = new Date("2018-05-25 12:00:00").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now an the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
if (days.toString().length < 2) {
days = "0" + days;
}
if (hours.toString().length < 2) {
hours = "0" + hours;
}
if (minutes.toString().length < 2) {
minutes = "0" + minutes;
}
if (seconds.toString().length < 2) {
seconds = "0" + seconds;
}
// Display the result in the element with id="countdown"
document.getElementById("countdown").innerHTML = days + " : " + hours + " : " +
minutes + " : " + seconds;
// If the count down is finished, write some text

clearInterval(x);
document.getElementById("countdown").innerHTML = "<a href='/register'>Countdown Expired</a>";

MDN discourages the use of a string in the date constructor because not all browsers implement this the same way.
If you do want to use date strings, I would recommend using a third party library like momentjs to parse these strings to make sure this works in every browser.
Just normalise the date and time
function getNormalisedDatetime(dString) { // yyyy-mm-dd hh:mm:ss
var parts = dString.split(" ");
var dParts = parts[0].split("-");
var tParts = parts[1].split(":");
return new Date(dParts[0],dParts[1]-1,dParts[2],tParts[0],tParts[1],tParts[2]);
}
function pad(num) {
return ("0"+num).slice(-2);
}
// Set the date we're counting down to
var countDownDate = getNormalisedDatetime("2018-05-25 12:00:00").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now an the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Display the result in the element with id="countdown"
document.getElementById("countdown").innerHTML = "" + pad(days) + " : " + pad(hours) + " : " +
pad(minutes) + " : " + pad(seconds);
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("countdown").innerHTML = "<a href='/register'>Countdown Expired</a>";
}
}, 1000);
