I tried to make countdown function , It is work unless hour time ! But I want to make 2 hours countdown time , I can't figure more ?
<div id="time"></div>
<script type="text/javascript">
var hour = 2 ;
var min = 30;
var countdown = hour * min * 60 * 1000;
//var countdown = hour * 3600 * min * 60 * 1000; also not working
var timeload = setInterval(function () {
countdown -= 1000;
var hr = Math.floor(countdown/(60 * 60 * 1000));
var min = Math.floor(countdown / (60 * 1000));
var sec = Math.floor((countdown - (min * 60 * 1000)) / 1000);
if (countdown <= 0) {
alert("Timeout !");
clearInterval(timeload);
}
else {
$("#time").html("<font color='red'>Allowed Time </font>" + hr + " : " + min + " : " + sec);
}
}, 1000);
</script>
Actual Started Time
Allowed Time 0 : 59 : 59
Expected Start Time Allowed Time 2 : 29 : 59
you can try this solution, you have an error on calculation time (hr, min, sec) it should modulus to maximum each value and also you wrong when convert hour and min to millisecond
var hour = 2 ;
var min = 30;
var countdown = (hour * 60 * 60 * 1000) + (min * 60 * 1000);
var timeload = setInterval(function () {
countdown -= 1000;
var hr = Math.floor( (countdown / (60 * 60 * 1000)) % 24 );
var min = Math.floor( (countdown / (60 * 1000)) % 60 );
var sec = Math.floor( (countdown / 1000) % 60 );
if (countdown <= 0) {
alert("Timeout !");
clearInterval(timeload);
}
else {
$("#time").html("<font color='red'>Allowed Time </font>" + hr + " : " + min + " : " + sec);
}
}, 1000);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="time"></div>
I think your calculations may be wrong. You don't want to multiply the hours by the minutes, but rather add them up in some way.
// useful numbers for calculations into milliseconds
var _1sec = 60 * 1000, _1min = 60 * _1sec, _1hr = 60 * min;
// renamed `hour` to cHR (countdown hour) so I can keep things straight in my head
var total_ms = (cHr * _1hr) + (cMin * _1min);
The hours/minutes/seconds for display also needs reworking.
// Mod (%) takes the remainder after division. So countdown % _1hr takes whatever is left over that doesn't go into whole hours, etc.
hr = Math.floor(countdown / _1hr);
min = Math.floor((countdown % _1hr) / _1min);
sec = Math.floor((countdown % _1min) / _1sec);
an example using diff between start and finish
var hour = 2;
var min = 30;
var finish = new Date();
finish.setHours(finish.getHours() + hour);
finish.setHours(finish.getHours(), finish.getMinutes() + min)
var diff = finish.getTime() - new Date().getTime()
var timeload = setInterval(function() {
diff -= 1000
var s = Math.floor(diff / 1000);
var m = Math.floor(s / 60);
var h = Math.floor(m / 60);
h %= 24;
m %= 60;
s %= 60;
if (diff <= 0) {
alert("FINISH!!");
clearInterval(timeload);
} else {
$("#time").html("<font color='red'>Allowed Time </font>" + h + " : " + m + " : " + s);
}
}, 1000)

I'm looking for a way to have a countdown timer that displays more than 24 hours instead of displaying days when there is more than one day left. In short, it shows 26:04:32 instead of 01:02:04:32.
I was working with this, but got stuck.
<script>
(function () {
var deadline = '2022/09/07 00:00';
function pad(num, size) {
var s = "0" + num;
return s.substr(s.length - size);
}
// fixes "Date.parse(date)" on safari
function parseDate(date) {
const parsed = Date.parse(date);
if (!isNaN(parsed)) return parsed
return Date.parse(date.replace(/-/g, '/').replace(/[a-z]+/gi, ' '));
}
function getTimeRemaining(endtime) {
let total = parseDate(endtime) - Date.parse(new Date())
let seconds = Math.floor((total / 1000) % 60)
let minutes = Math.floor((total / 1000 / 60) % 60)
let hours = Math.floor((total / (1000 * 60 * 60)) % 24)
let days = Math.floor(total / (1000 * 60 * 60 * 24))
return { total, days, hours, minutes, seconds };
}
function clock(id, endtime) {
let days = document.getElementById(id + '-days')
let hours = document.getElementById(id + '-hours')
let minutes = document.getElementById(id + '-minutes')
let seconds = document.getElementById(id + '-seconds')
var timeinterval = setInterval(function () {
var time = getTimeRemaining(endtime);
if (time.total <= 0) {
clearInterval(timeinterval);
} else {
days.innerHTML = pad(time.days, 2);
hours.innerHTML = pad((time.hours, 2) + (24 * (time.days, 2)), 2);
minutes.innerHTML = pad(time.minutes, 2);
seconds.innerHTML = pad(time.seconds, 2);
}
}, 1000);
}
clock('js-clock', deadline);
})();
</script>
Just don't modulo (%) the hours with 24, and get rid of everything related to days:
let hours = Math.floor((total / (1000 * 60 * 60))); // will happily go > 24
I want to find difference between two time with milliseconds value in Javascript.
As you can see below snapshot, where I calculated two time values in Excel.
My expectation exactly same calculated value with JS code.
I tried some code snippet but I got slightly difference in seconds.
var d1 = '2020-12-15 01:00:23.788';
var d2 = '2020-12-15 01:00:55.482';
var date1 = new Date(d1);
var date2 = new Date(d2);
//date2 += 500;
//date2 = new Date(date2);
//date2.setMilliseconds(5);
var date1_ms = date1.getTime();
var date2_ms = date2.getTime();
// Calculate the difference in milliseconds
var difference_ms = date2_ms - date1_ms;
//take out milliseconds
difference_ms = difference_ms / 1000;
var seconds = Math.floor(difference_ms % 60);
difference_ms = difference_ms / 60;
var minutes = Math.floor(difference_ms % 60);
difference_ms = difference_ms / 60;
var hours = Math.floor(difference_ms % 24);
var demo = hours + ' hours, ' + minutes + ' minutes, and ' + seconds + ' seconds.' + difference_ms;
document.getElementById("demo").innerHTML = demo;
<h2>JavaScript new Date()</h2>
<p>new Date() creates a new date object with the current date and time:</p>
<p id="demo"></p>
OUTPUT:
new Date() creates a new date object with the current date and time:
0 hours, 0 minutes, and 31 seconds.0.008803888888888889
JS does the same when correctly implemented
I tried with more interesting times
// Excel: 02:10:55,482 - 01:09:23,788 = 01:01:31,694

return `${hours}:${minutes}:${seconds}.${ms}`
}
const from = "01:09:23,788"
const to = "02:10:55.482"

let d = new Date()
d.setHours(fromhh, frommm, fromss, fromms)
const fromTime = d.getTime()

const toTime = d.getTime()
const diffInMS1 = toTime - fromTime
console.log(diffInMS1)

I have a script that countdowns timestamp. It is working fine but the problem it keeps going less than 0 into negative. I want it to stop at zero.
// $nowtime is a date in future
var startLive = new Date("<?php echo $nowtime; ?>");
var timestamp = startLive - Date.now();
timestamp /= 1000; // from ms to seconds
function component(x, v) {
return Math.floor(x / v);
}
var $div = $('.time');
timer = setInterval(function() {
timestamp--;
var days = component(timestamp, 24 * 60 * 60),
hours = component(timestamp, 60 * 60) % 24,
minutes = component(timestamp, 60) % 60,
seconds = component(timestamp, 1) % 60;
$div.html(days + " days, " + hours + ":" + minutes + ":" + seconds);
}, 1000);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
Output looks like 1 Days, 6:10:30
Problem is if it is less than zero it still goes in negative. something like -3 days, -3:-5:-5
How to stop at 0.
Thanks.
timer = setInterval(function() {
/* if timestamp <= 0 return means skip rest of function */
if(timestamp <= 0) {
clearInterval(timer);
return;
}
timestamp--;
var days = component(timestamp, 24 * 60 * 60),
hours = component(timestamp, 60 * 60) % 24,
minutes = component(timestamp, 60) % 60,
seconds = component(timestamp, 1) % 60;
$div.html(days + " days, " + hours + ":" + minutes + ":" + seconds);
}, 1000);
if(timestamp <= 0)
{
clearInterval(timer);
}
Hi I am having a hard time making this countdown work for me. I am trying to make it count down to every sunday at 11:15am since that is when our church service starts. Can anyone pleaes help me? I have the code here.
function croAnim(){
// IF THERE'S A COUNTDOWN
if ($('ul.cro_timervalue').length !== 0) {
// GET ALL THE INSTANCES OF THE TIMER
$('ul.cro_timervalue').each(function() {
var $this = $(this),
timesets = $this.data('cro-countdownvalue'),
now = new Date(),
tset = Math.floor(now / 1000),
counter1 = timesets - tset;
// CALCULATE SECONDS
var seconds1 = Math.floor(counter1 % 60);
seconds1 = (seconds1 < 10 && seconds1 >= 0) ? '0'+ seconds1 : seconds1;
// CALCULATE MINUTES
counter1 =counter1/60;
var minutes1 =Math.floor(counter1 % 60);
minutes1 = (minutes1 < 10 && minutes1 >= 0) ? '0'+ minutes1 : minutes1;
// CALCULATE HOURS
counter1=counter1/60;
var hours1=Math.floor(counter1 % 24);
hours1 = (hours1 < 10 && hours1 >= 0) ? '0'+ hours1 : hours1;
// CALCULATE DAYS
counter1 =counter1/24;
var days1 =Math.floor(counter1);
days1 = (days1 < 10 && days1 >= 0) ? '0'+ days1 : days1;
// ADD THE VALUES TO THE CORRECT DIVS
$this.find('span.secondnumber').html(seconds1);
$this.find('span.minutenumber').html(minutes1);
$this.find('span.hournumber').html(hours1);
$this.find('span.daynumber').html(days1);
});
}
}
// CREATE A INTERVAL FOR THE TIMER
croInit = setInterval(croAnim, 100);
I answered a similar question about a week or so ago. I have a really simple countdown function already written. The trick is to modify it to get the next Sunday # 11:15 am, which I've written a function for.
var getNextSunday = function () {
var today = new Date(),
day = today.getDay(), // 1 for Mon, 2 for Tue, 3 for Wed, etc.
delta = 7 - day;
var sunday = new Date(today.getTime() + (delta * 24 * 3600 * 1000));
sunday.setHours(11);
sunday.setMinutes(15);
sunday.setSeconds(0);
return sunday;
}
var t = getNextSunday(),
p = document.getElementById("time"),
timer;
var u = function () {
var delta = t - new Date(),
d = delta / (24 * 3600 * 1000) | 0,
h = (delta %= 24 * 3600 * 1000) / (3600 * 1000) | 0,
m = (delta %= 3600 * 1000) / (60 * 1000) | 0,
s = (delta %= 60 * 1000) / 1000 | 0;
if (delta < 0) {
clearInterval(timer);
p.innerHTML = "timer's finished!";
} else {
p.innerHTML = d + "d " + h + "h " + m + "m " + s + "s";
}
}
timer = setInterval(u, 1000);
<h1 id="time"></h1>
This should be easy enough to adapt to fit your website's needs. The only tricky part might be my use of
h = (delta %= 24 * 3600 * 1000) / (3600 * 1000) | 0
delta %= ... returns delta, after performing the %=. This was just to save characters. If you don't like this, you can just separate the delta %= ... part:
delta %= 24 * 3600 * 1000;
h = delta / (3600 * 1000) | 0;
// ... do the same for the rest
This object uses a few semi-advanced javascript ideas (closures and * IIFE*) so hopefully it is easy-ish to understand. If you have any questions feel free to leave a comment.
var churchtime = (function (){
// Total seconds passed in the week by sunday 11:15am
var magic_number = 558900;
var now;
var rawtime = function (){
//updates now with the current date and time
now = new Date()
//Converts now into pure seconds
return (((((((now.getDay()-1)*24)+now.getHours())*60)+now.getMinutes())*60)+now.getSeconds());
};
//closure
return {
raw_countdown : function (){
return Math.abs(rawtime()-magic_number);
},
countdown : function(){
var time = Math.abs(rawtime()-magic_number)
var seconds = time % 60, time = (time - seconds)/60;
var minutes = time % 60, time = (time - minutes)/60;
var hours = time % 24, time = (time - hours)/24;
var days = time;
return [days,hours,minutes,seconds];
}
}
})(558900); //<- Total seconds passed in the week by sunday 11:15am
churchtime.raw_countdown()// returns the raw number of seconds until church
churchtime.countdown() // returns an array of time until church [days,hours,minutes,seconds]
Once you have an object like churchtime, it should be super easy to implement.
For example:
var churchtime = (function(magic_number) {
var now;
var rawtime = function() {
//updates now with the current date and time
now = new Date()
//Converts now into pure seconds
return (((((((now.getDay() - 1) * 24) + now.getHours()) * 60) + now.getMinutes()) * 60) + now.getSeconds());
};
//closure
return {
raw_countdown: function() {
return Math.abs(rawtime() - magic_number);
},
countdown: function() {
var time = Math.abs(rawtime() - magic_number)
var seconds = time % 60,
time = (time - seconds) / 60;
var minutes = time % 60,
time = (time - minutes) / 60;
var hours = time % 24,
time = (time - hours) / 24;
var days = time;
return [days, hours, minutes, seconds];
}
}
})(); //<- IIFE
AutoUpdate = function AutoUpdate() {
var time = churchtime.countdown();
document.getElementById("day").innerHTML = time[0];
document.getElementById("hour").innerHTML = time[1];
document.getElementById("min").innerHTML = time[2];
document.getElementById("sec").innerHTML = time[3];
setTimeout(AutoUpdate, 900); //Calls it's self again after .9 seconds
}(); //<- IIFE
<h1>Day:<span id="day"></span> Hour:<span id="hour"></span>
Minute:<span id="min"></span> second: <span id="sec"></span></h1>
My code is located below. I'm trying to set a countdown, however I can't figure out how to set the timer to operate. I've tried changing the "var setting". When I do it seems that the countdown works, however it glitches and the numbers appear but all go back to "0". Really confused. Someone Please help!
(function($) {
$.fn.countdown = function(options) {
var settings = { 'date': "30 september 2014 16:24:00" };
if(options) {
$.extend(settings, options);
}
this_sel = $(this);
function count_exec() {
eventDate = Date.parse(settings['date']) / 1000; // Parse the date string
currentDate = Math.floor($.now() / 1000); // Find the timestamp for now
seconds = eventDate - currentDate; // Find the number of seconds remaining
if (seconds <= 0) { // After the event date has passed
days = 0;
hours = 0;
minutes = 0;
seconds = 0;
} else {
days = Math.floor(seconds / (60 * 60 * 24)); // Divide to find the number of days remaining
seconds -= days * 60 * 60 * 24; // Subtract the number of (complete, => 24 hours) days calculated above
hours = Math.floor(seconds / (60 * 60)); // Get the number of hours from that modified number ^
seconds -= hours * 60 * 60;
minutes = Math.floor(seconds / 60);
seconds -= minutes * 60;
}
this_sel.find('#days').val(days).trigger('change');
this_sel.find('#hours').val(hours).trigger('change');
this_sel.find('#mins').val(minutes).trigger('change');
this_sel.find('#secs').val(seconds).trigger('change');
} // End of count_exec();
count_exec();
interval = setInterval(count_exec, 1000);
} // End of the main function
}) (jQuery);
