How to add a specific timezone to a countdown timer - javascript

The goal is to have the countdown timer to count down to a specific time in NYC (EST).
So the the timer goes to zero at 12:00 in NYC but in LA it would go to zero at 09:00
This is the code I use from W3Schools. But I don't have enough knowledge to add the timezone.
Can anyone help please :)
<script>
// Set the date we're counting down to
var countDownDate = new Date("Dec, 2019 12:00:00 GMT-0500").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 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 = hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>

Custom field calculation in wordpress using Javascript

I have implemented the code below in my site, to display a running timer. The site is running on Wordpress. At the moment the date is input in the code (so it applied site wide). I am looking to have a running timer on each post.
I need to change the code below so that I can use a custom field on each post called "expiry" as the date, instead of the hardwired date below (newDate("Jan 5, 2021 15:37:25).getTime()
<!-- Display the countdown timer in an element -->
<p id="demo"></p>
<script>
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2021 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);
// Display the result in the element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
</script>
The above code is sourced from here
My site is here
Thanks in advance
below steps is your requirements:
1) in custom field expiry set return format as custom "F j, Y g:i:s"
example link (https://prnt.sc/pqg79l)
2) add this function in functions.php
function functionname() {
global $post;
$field= get_field('expiry_date', $post->ID);
echo '<input type="hidden" id="date" value="'.$field.'">';
}
add_action( 'template_redirect', 'functionname' );
3) in your js file add below script
var $= jQuery;
var d = $("#date").val();
console.log(d);
// Set the date we're counting down to
var countDownDate = new Date(d).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="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "EXPIRED";
}
}, 1000);
make sure you have to add <p id="demo"></p> where you want to show in post
I have tried this code..It's totally working fine..I hope i have helped you by this

Set startdate to countdown

I have a countdown that ends at a specific time and date.
Is it possible to set a starting date for the countdown?
Start: June 14, 2018 15:00:00
End: June 17, 2018 23:59:59
// Set the date we're counting down to
var countDownDate = new Date("June 17, 2018 23:59:59").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);
// Output the result in an element with id="demo"
document.getElementById("countdown").innerHTML = "TEXT Countdown" + days + " days, " + hours + " h, "
+ minutes + " min & " + seconds + " sec";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("countdown").innerHTML = "TEXT after countdown";
}
}, 1000);
<div id="countdown"></div>
Just delay the call to setInterval until the time you want. Your best bet, since timers get throttled on inactive tabs, is to check periodically and then kick things off when the time arrives:
var waitingTimer = setInterval(function() {
if (Date.now() < Date.parse("2018-06-14T15:00:00")) {
return;
}
clearInterval(waitingTimer);
// ...start the countdown
}, 1000);
You might want to express the time in UTC, since unfortunately the spec on what those strings mean without a timezone indicator changed (twice), whereas if you put the time in UTC and add a Z to the string, it's reliable.

How to continuously restart countdown when it elapse

I'm using a countdown timer script that I've come across online and modified slightly to suit my website. This works perfectly for counting down to a set date/time but I need the timer to pause for about 1 hour and continue counting for 7 days. For example, when it reaches its end which is Wednesday 00:00:00, it should wait for an hour and then starts counting again till next Wednesday and so on and so fort.
-please i need help!
-here is the code i use
function teus(){
// Set the date we're counting down to
var countDownDate = new Date("Apr 3, 2018 18:00:00").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);
// Output the result in an element with id="demo"
document.getElementById("teu").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s " + "";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("teu").innerHTML = "Service Time";
}
}, 1000);
}
teus()

timer data start for next week

function countDown(){
// Set the date we're counting down to
var countDownDate = new Date("july 11, 2017 10:19:00").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);
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is over, write some text
if (distance < 0) {
countDownDate = new Date("july 18, 2017 10:19:00").getTime();
}
}, 1000);
}
countDown();
what I want to reach is the every week the timer will start count to the next week.
I have something that start every week in the same day and in the same hour.
I don't want to rewrite the code every week :/
Thank you.
so why so much calculation is needed just to calculate how many seconds are remaining to start of next week? for example I am writing a sample code to calculate it.
function distranceToNextWeekStartInSeconds() {
var now = new Date()
var dayDiff = 7 - now.getDay();
var startOfNextWeek = new Date(now.valueOf());
startOfNextWeek.setDate(now.getDate() + dayDiff);
startOfNextWeek.setHours(0);
startOfNextWeek.setMinutes(0);
startOfNextWeek.setSeconds(0);
return Math.floor((startOfNextWeek - now) / 1000);
}
console.log('Seconds remaining to next week start: ' + distranceToNextWeekStartInSeconds())
and you can simply call this function inside your timer for a live calculation and display purpose, That's It.
I assumed you wanted to count down to every next tuesday at 10:19:00.
I'm too lazy right now to test every cases, ut I think it should work.
function getNextTuesday() {
// Get the date from now
var date = new Date();
// Set target hour/minute/seconds
date.setHours(10);
date.setMinutes(19);
date.setSeconds(0);
// Seek for the next tuesday
var actualDay = date.getDay();
var targetDay = 2; //Tuesday
// diff will give us the day span between today and the next tuesday
var diff = targetDay - actualDay;
// If the diff is less than 0 (we're sunday or monday, or we fall on the exact day, minutes after the target hour) then add a week
if (diff < 0 || (date.getTime() - new Date().getTime()) <= 0) {
diff += 7;
}
// Finally add the day span to the current date
date.setDate(date.getDate() + diff);
return date;
}
function countDown() {
// Set the date we're counting down to
var countDownDate = getNextTuesday();
// 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 (distance < 0) {
// If the count down is over, write some text
document.getElementById("demo").innerHTML = 'IT\'S HAPPENING !';
countDownDate = getNextTuesday();
} else {
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
}
}, 1000);
}
countDown();
<div id="demo"></div>

Display None on time

I have a Javascript code for a countdown timer. I want to use this code in a online shop order process. However I don't want to edit the date every day manually.
Now my question is: How can i display the div container from 6am to 2am (06.00 to 14.00).
From 14.00 to 06.00 i want that this container is display:none
// Set the date we're counting down to
var countDownDate = new Date("Jan 5, 2018 18:00:00").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="demo"
document.getElementById("timer").innerHTML = "Bestellen Sie innerhalb der nächsten <span style='font-size:18px;color: #008a00!important;'>" + hours + " Stunden und "
+ minutes + " Minuten " + "</span>und wir versenden noch am gleichen Tag!";
// If the count down is finished, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("timer").innerHTML = "EXPIRED";
}
}, 1000);
var d = new Date();
if(d.getHours() >= 7 && d.getHours() <= 18 ){
$("#timer").show();
$(".closed").hide();
} else {
$(".closed").show();
$("#timer").hide();
}
<!-- Display the countdown timer in an element -->
<p id="timer"></p>
<p class="closed"></p>
Have anyone a solution for that?
