Set a GMT on a countdown script - javascript

How can I set a GMT to date.Now()?
var countDownDate = getNextDayOfWeek(new Date(),0,21);
// 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)).toString();
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)).toString();
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60)).toString();
var seconds = Math.floor((distance % (1000 * 60)) / 1000).toString();
// Add 0 when value are < 10
hours = (hours < 10) ? "0"+hours : hours;
minutes = (minutes < 10) ? "0"+minutes : minutes;
seconds = (seconds < 10) ? "0"+seconds : seconds;
var grb = jq("#grb");
// Display the result in the element with id="grb"
grb.html(days + "d " + hours + "h " + minutes + "m " + seconds + "s");
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
var one_hour = -60 * -60 * -1000;
if(distance < one_hour){
grb.html("GRB is finished!");
}else{
grb.html("GRB is open!");
}
}
}, 1000);
});
It keeps using the time of your computer, and I want to use a timezone to be stored everytime.
I have tried TimeZoneOffset, didn't worked, any help would be appreciated.

please see this
var now = new Date();
var nowUTC = new Date(now.getUTCFullYear(), now.getUTCMonth(), now.getUTCDate(), now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds());
var distance = end - nowUTC;

How to make countdown time after 0 0 0 0 back to countdown again in javascript?

I just want to know how to make countdown after 0 0 0 0 its directly back to 23:59:59 so i have a problem when i try to create countdown function when its expired it will go to -0d -0h -0m -1s , -0d -0h -0m -2s but when i refresh it back to 23.59.58 , 23,59,57. i just want to know after clear interval it direcy go to 23.59.59 not -0d -0h -0m -0s . this is my script
countdown.js
function warTime2(countDownDate) {
var countDownDate = new Date();
countDownDate.setHours(14);
countDownDate.setMinutes(0);
countDownDate.setSeconds(0);
var now = new Date();
if (now.getHours() < countDownDate.getHours()) {
countDownDate = countDownDate;
} else if (countDownDate.getHours() <= now.getHours()) {
countDownDate.setDate(countDownDate.getDate() + 1);
}
var x = setInterval(function () {
var now = new Date();
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
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 (hours < 10) {
hours = "0" + hours;
}
if (minutes < 10) {
minutes = "0" + minutes;
}
if (seconds < 10) {
seconds = "0" + seconds;
}
document.getElementById("second_chip_war").innerHTML =
"02:00 PM War Start in " + hours + ":" + minutes + ":" + seconds;
if (distance < 0) {
clearInterval(x);
let newDate = countDownDate + 8 * 3600 * 1000;
warTime2(newDate);
}
}, 1000);
}
Thank you, glad to hear if you want to help me
You need to check whether distance is less than 0 when you first assign it, and if so, increase countDownDate by a day before recomputing distance and continuing the function:
function warTime2(countDownDate) {
var countDownDate = new Date();
countDownDate.setHours(14);
countDownDate.setMinutes(0);
countDownDate.setSeconds(0);
var now = new Date();
if (now.getHours() < countDownDate.getHours()) {
countDownDate = countDownDate;
} else
if (countDownDate.getHours() <= now.getHours()) {
countDownDate.setDate(countDownDate.getDate() + 1);
}
var x = setInterval(function() {
var now = new Date();
var distance = countDownDate - now;
if (distance < 0) {
// countdown complete, add a day to countDownDate and restart
countDownDate.setDate(countDownDate.getDate() + 1);
distance = countDownDate - now;
}
// Time calculations for days, hours, minutes and seconds
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 (hours < 10) {
hours = "0" + hours;
}
if (minutes < 10) {
minutes = "0" + minutes;
}
if (seconds < 10) {
seconds = "0" + seconds;
}
document.getElementById("second_chip_war").innerHTML = "02:00 PM War Start in " + hours + ":" +
minutes + ":" + seconds;
}, 1000);
}
warTime2('2020-06-21');
<div id="second_chip_war"></div>

Countdown doesn't reset for next year

We had this countdown for Christmas, but now it shows expired instead of resetting to next year
// Set the date we're counting down to
var year = new Date().getFullYear();
var countDownDate = new Date("Dec 24, " + year + " 23:00:00").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the 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 in the element with id="clock"
document.getElementById("clock").innerHTML = days + " days " + hours + "hrs. " + minutes + "mins. " + seconds + "secs. ";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("clock").innerHTML = "EXPIRED";
}
}, 1000);
The 'expired' message should maybe show during the 25-26th of December and then reset back to counting on 27th till next year?
I cant see where you check if your date is later than december, 26th, here should be code like this
if (days < -2) {
countDownDate = new Date("Dec 24, " + (year + 1) + " 23:00:00").getTime();
} else if (distance < 0) {
clearInterval(x);
document.getElementById("clock").innerHTML = "EXPIRED";
}
or better just in the very beginning write
var now = new Date()
var year = now.getFullYear() + (now.getMonth() == 11 && now.getDate() > 26)
Below are suggested edits to your code. Near the top, we decide which year's Christmas to count down to.
If you look over the code and commments, you can see more about how date information can be used in JavaScript.
If you want to know more, there's great information at MDN's Date Object page.
// Get a Date object for the current time before starting the countdown
let startTime = new Date()
// Get the year, month and day from the date object
let year = startTime.getFullYear();
let monthIndex = startTime.getMonth();
let dayOfMonth = startTime.getDate();
//console.log (`${year} ${monthIndex} ${dayOfMonth}`);
if (monthIndex === 11 && dayOfMonth > 27){ // Jan has monthIndex == 0
year = year + 1; // Use next year
}
// Set the date we're counting down to
let countDownDate = new Date("Dec 24, " + year + " 23:00:00").getTime();
// Start the countdown, updating the display every 1 second
var x = setInterval(function() {
// Get a Date object for the current second of the countdown
var date = new Date()
// Get the timestamp from the Date object
var now = date.getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Function to show "day" if 1 day, "days" if 2 or more days, etc.
function pluralIfAppropriate(value, singularLabel, pluralLabel){
if(value == 1){
return singularLabel;
}
else{
if(pluralLabel == undefined){
pluralLabel = singularLabel + "s";
}
return pluralLabel;
}
}
// Builds the display text
let displayText = `${days} ${pluralIfAppropriate(days, "day")} ${hours}${pluralIfAppropriate(hours, "hr")} ${minutes}${pluralIfAppropriate(minutes, "min")} ${seconds}${pluralIfAppropriate(seconds, "sec")}`;
// Displays the displayText in the element with id="clock"
document.getElementById("clock").innerHTML = displayText;
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("clock").innerHTML = "EXPIRED";
}
}, 1000);

How to make timer in JavaScript?

I want reverse timer for session time out. I got one code on codepen. This code is clockwise timer , I tried to make it anti-clock wise , I am failed. Please suggest me. I want to make 1 hour or 59min 59sec time out. Please help me Here is the codepen demo.
if((intervalCounter%1000)==0){
currentTime += 1000;
var appendHour = currentTime / (1000 * 60 * 60) | 0;
var appendMinute = currentTime % (1000 * 60 * 60) / (1000 * 60) | 0;
var appendSecond = currentTime % (1000 * 60) / 1000 | 0;
appendHour = appendHour < 10 ? "0" + appendHour : appendHour;
appendMinute = appendMinute < 10 ? "0" + appendMinute : appendMinute;
appendSecond = appendSecond < 10 ? "0" + appendSecond : appendSecond;
hour.html(appendHour);
min.html(appendMinute);
sec.html(appendSecond);
}
This code is work for anti-clockwise direction.I hope you get some idea from below example.
// Set the date we're counting down to
var countDownDate = new Date("July 5, 2019 15:37:25").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the 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);
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "

// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);

Show countdown timer in HH:MM:SS instead of H:M:S in Javascript

I managed to display a countdown timer in H:M:S format.
May I know how can I display it to HH:MM:SS format? Example, let's say for 300 hours, 1 minute and 1 second, it will display as 300:01:01 instead of 300:1:1 .
This is what I got so far.
// Set the date we're counting down to
var countDownDate = new Date("Aug 31, 2019 22:55:00").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 and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var hours = Math.floor(distance / (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="demo"
document.getElementById("demo").innerHTML = hours + " : "
+ minutes + " : " + seconds + "";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
<p id="demo"></p>
Test for values less than 10 and append a leading zero
// Set the date we're counting down to
var countDownDate = new Date("Aug 31, 2019 22:55:00").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 and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var hours = Math.floor(distance / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
if (hours < 10) hours = '0'+ hours;
if (minutes < 10) minutes = '0'+ minutes;
if (seconds < 10) seconds = '0'+ seconds;
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = hours + " : "
+ minutes + " : " + seconds + "";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);

As kamoroso94 mentioned in a comment, you could also use padstart()
// Set the date we're counting down to
var countDownDate = new Date("Aug 31, 2019 22:55:00").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 and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var hours = Math.floor(distance / (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="demo"
document.getElementById("demo").innerHTML = hours.toString().padStart(2, '0') + " : "
+ minutes.toString().padStart(2, '0') + " : " + seconds.toString().padStart(2, '0') + "";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
<p id="demo"></p>
You can prefix(aka padLeft) the hours, minutes and seconds with arbitrary length strings as below:
function padLeft(padding, data) {
return +(padding + data).slice(-padding.length);
}
padLeft('00', 3) // '03'
padLeft('00', 13) // '13'
padLeft('0000', 3) // '0003'
You can do this with a simple replace:
var timeString = (hours + ':' + minutes + ':' + seconds).replace(/\b(\d)\b/g, '0$1');
EDIT: in case you do not want to prepend a zero to the hours:
var timeString = (hours + ':' + minutes + ':' + seconds).replace(/:(\d)\b/g, ':0$1');
// Set the date we're counting down to
var countDownDate = new Date("Aug 31, 2019 22:55:00").getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get todays date and time
var now = new Date().getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var hours = Math.floor(distance / (1000 * 60 * 60));
var minutes = (`0${Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60))}`).substr(-2); ;
var seconds = (`0${Math.floor((distance % (1000 * 60)) / 1000)}`).substr(-2);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = `${hours}:${minutes}:${seconds}`;
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);

Countdown timer expires start a different countdown

I have the following code. I want when this timer expires, another timer should start instead of expired text.
var countDownDate = new Date("Oct 25, 2017 15:37:25").getTime();
var x = setInterval(function() {
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);
document.getElementById("demo").innerHTML = days + " Days " + hours + " Hrs "
+ minutes + " Min " + seconds + " Sec ";
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "T**imer Expired - instead of this another timer**";
}
}, 1000);
Create a function, and call it every time the timer is finished.
$(document).ready(function() {
var i = 1 ;
setTimer(i) ;
}) ;
function setTimer(i) {
var countDownDate = new Date().getTime() + 3000 ;
var x = setInterval(function() {
var now = new Date().getTime() ;
var distance = countDownDate - now ;
if (distance < 0) {
clearInterval(x);
console.log("Timer " + i + " Finished. New Timer Stated!") ;
setTimer(i+1) ;
}
else {
console.log("Timer " + i + " Running") ;
}
}, 1000);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
This code should do the trick. Each time the counter get to 0, you redefined your count down to the same amount of time there was initially between countDownDate and Now. If this amount is variable, you might modify the assignment of distanceToAdd
// Changed the value to reach for the demo
var countDownDate = new Date().getTime() + 20000;
// Fixed Value to add each time the counter get to 0
var distanceToAdd = countDownDate - new Date().getTime();
var x = setInterval(function() {
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);
if (distance < 0) {
//Add Time to your timer goal instead of canceling interval
countDownDate += distanceToAdd;
}
else {
document.getElementById("demo").innerHTML = days + " Days " + hours + " Hrs "
+ minutes + " Min " + seconds + " Sec ";
}
}, 1000);
