JS Countdown that can reset every week on a specific day and time

My webpage timenite.com/item-shop shows a countdown that resets every day at 5:30 AM IST, I want to make a similar page in the directory timenite.com/xx and set it to reset every week on Thursdays at 8:30 PM IST.
Below is the script of what is being used currently on the item-shop page, there were actually two script files but I have combined them into one, just in case.
Help would be appreciated, thank you.
(function ($) {
$.fn.countdown = function (options, callback) {
var settings = $.extend({
date: null,
offset: null,
day: 'Day',
days: 'Days',
hour: 'Hour',
hours: 'Hours',
minute: 'Minute',
minutes: 'Minutes',
second: 'Second',
seconds: 'Seconds'
}, options);
// Throw error if date is not set
if (!settings.date) {
$.error('Date is not defined.');
}
// Throw error if date is set incorectly
if (!Date.parse(settings.date)) {
$.error('Incorrect date format, it should look like this, 12/24/2012 12:00:00.');
}
// Save container
var container = this;
/**
* Change client's local date to match offset timezone
* #return {Object} Fixed Date object.
*/
var currentDate = function () {
// get client's current date
var date = new Date();
// turn date to utc
var utc = date.getTime() + (date.getTimezoneOffset() * 60000);
// set new Date object
var new_date = new Date(utc + (3600000*settings.offset));
return new_date;
};
/**
* Main countdown function that calculates everything
*/
function countdown () {
var target_date = new Date(settings.date), // set target date
current_date = currentDate(); // get fixed current date
// difference of dates
var difference = target_date - current_date;
// if difference is negative than it's pass the target date
if (difference < 0) {
// stop timer
clearInterval(interval);
if (callback && typeof callback === 'function') callback();
return;
}
// basic math variables
var _second = 1000,
_minute = _second * 60,
_hour = _minute * 60,
_day = _hour * 24;
// calculate dates
var days = Math.floor(difference / _day),
hours = Math.floor((difference % _day) / _hour),

seconds = Math.floor((difference % _minute) / _second);
// based on the date change the refrence wording
var text_days = (days === 1) ? settings.day : settings.days,
text_hours = (hours === 1) ? settings.hour : settings.hours,

How to remove the "day" when the countdown clock is under 24 hours

I'd like the day numbers to disappear when the clock goes below 24 hours instead of having it read "00".
I've attempted a few solutions, but nothing seems to be working for me. I can attach the HTML/CSS if it is needed.
Here is my js:
//
(function(e){
e.fn.countdown = function (t, n){
function i(){
eventDate = Date.parse(r.date) / 1e3;
currentDate = Math.floor(e.now() / 1e3);
//
if(eventDate <= currentDate){
n.call(this);
clearInterval(interval)
}
//
seconds = eventDate - currentDate;
days = Math.floor(seconds / 86400);
seconds -= days * 60 * 60 * 24;
hours = Math.floor(seconds / 3600);
seconds -= hours * 60 * 60;
minutes = Math.floor(seconds / 60);
seconds -= minutes * 60;
//
days == 1 ? thisEl.find(".timeRefDays").text("Days") : thisEl.find(".timeRefDays").text("Days");
hours == 1 ? thisEl.find(".timeRefHours").text("Hours") : thisEl.find(".timeRefHours").text("Hours");
minutes == 1 ? thisEl.find(".timeRefMinutes").text("Minutes") : thisEl.find(".timeRefMinutes").text("Minutes");
seconds == 1 ? thisEl.find(".timeRefSeconds").text("Seconds") : thisEl.find(".timeRefSeconds").text("Seconds");
//
if(r["format"] == "on"){
days = String(days).length >= 2 ? days : "0" + days;
hours = String(hours).length >= 2 ? hours : "0" + hours;
minutes = String(minutes).length >= 2 ? minutes : "0" + minutes;
seconds = String(seconds).length >= 2 ? seconds : "0" + seconds
}
//
if(!isNaN(eventDate)){
thisEl.find(".days").text(days);
thisEl.find(".hours").text(hours);
thisEl.find(".minutes").text(minutes);
thisEl.find(".seconds").text(seconds)
}
else{
errorMessage = "Invalid date. Example: 27 March 2015 17:00:00";
alert(errorMessage);
console.log(errorMessage);
clearInterval(interval)
}
}
//
var thisEl = e(this);
var r = {
date: null,
format: null
};
//
t && e.extend(r, t);
i();
interval = setInterval(i, 1e3)
}
})(jQuery);
//
$(document).ready(function(){
function e(){
var e = new Date;
e.setDate(e.getDate() + 60);
dd = e.getDate();
mm = e.getMonth() + 1;
y = e.getFullYear();
futureFormattedDate = mm + "/" + dd + "/" + y;
return futureFormattedDate
}
//
$("#countdown").countdown({
date: "05 December 2019 14:00:00",
format: "on"
});
});
});
I'm not really sure what other details I can provide, but please let me know if there is anything else I can submit to make this easier to answer.

Need help resetting a javascript countdown timer

So I am a web designer and I inherited a site from another developer. The site in question is for an annual event and features a countdown timer on the home page. I am still pretty new to js and could use some help resetting the timer to next years date of March 1st, 2019. I have posted the code for the count down timer below. Any advice would be much appreciated!
(function($) {
$.fn.countdown = function(options, callback) {
//custom 'this' selector
thisEl = $(this);
//array of custom settings
var settings = {
'date': null,
'format': null
};
//append the settings array to options
if(options) {
$.extend(settings, options);
}
//main countdown function
function countdown_proc() {
eventDate = Date.parse(settings['date']) / 1000;
currentDate = Math.floor($.now() / 1000);
if(eventDate <= currentDate) {
callback.call(this);
clearInterval(interval);
}
seconds = eventDate - currentDate;
days = Math.floor(seconds / (60 * 60 * 24)); //calculate the number of days
seconds -= days * 60 * 60 * 24; //update the seconds variable with no. of days removed
hours = Math.floor(seconds / (60 * 60));
seconds -= hours * 60 * 60; //update the seconds variable with no. of hours removed
minutes = Math.floor(seconds / 60);
seconds -= minutes * 60; //update the seconds variable with no. of minutes removed
//conditional Ss
if (days == 1) { thisEl.find(".timeRefDays").text("day"); } else { thisEl.find(".timeRefDays").text("days"); }
if (hours == 1) { thisEl.find(".timeRefHours").text("hour"); } else { thisEl.find(".timeRefHours").text("hours"); }
if (minutes == 1) { thisEl.find(".timeRefMinutes").text("minute"); } else { thisEl.find(".timeRefMinutes").text("minutes"); }
if (seconds == 1) { thisEl.find(".timeRefSeconds").text("second"); } else { thisEl.find(".timeRefSeconds").text("seconds"); }
//logic for the two_digits ON setting
if(settings['format'] == "on") {
days = (String(days).length >= 2) ? days : "0" + days;
hours = (String(hours).length >= 2) ? hours : "0" + hours;
minutes = (String(minutes).length >= 2) ? minutes : "0" + minutes;
seconds = (String(seconds).length >= 2) ? seconds : "0" + seconds;
}
//update the countdown's html values.
if(!isNaN(eventDate)) {
thisEl.find(".days").text(days);
thisEl.find(".hours").text(hours);
thisEl.find(".minutes").text(minutes);
thisEl.find(".seconds").text(seconds);
} else {
alert("Invalid date. Here's an example: 12 Tuesday 2012 17:30:00");
clearInterval(interval);
}
}
//run the function
countdown_proc();
//loop the function
interval = setInterval(countdown_proc, 1000);
}
}) (jQuery);

You need to construct a date via the Date object and then pass the date and a callback function to countdown
const oneHourFromNow= new Date();
oneHourFromNow.setHours(oneHourFromNow.getHours() + 1);
const config = {
"date": oneHourFromNow.toString(),
"format": "off"
}
const callbackFunc = function() {console.log("Do something");}
$.fn.countdown(config , callbackFunc );
(function($) {
let interval;
$.fn.countdown = function(options, callback) {
//custom 'this' selector
// I hard-coded this ***
thisEl = $('#countdown-timer');
//array of custom settings
var settings = {
'date': null,
'format': null
};
//append the settings array to options
if(options) {
$.extend(settings, options);
}
//main countdown function
function countdown_proc() {
eventDate = Date.parse(settings['date']) / 1000;
currentDate = Math.floor($.now() / 1000);
if(eventDate <= currentDate) {
callback.call(this);
clearInterval(interval);
}
seconds = eventDate - currentDate;
days = Math.floor(seconds / (60 * 60 * 24)); //calculate the number of days
seconds -= days * 60 * 60 * 24; //update the seconds variable with no. of days removed
hours = Math.floor(seconds / (60 * 60));
seconds -= hours * 60 * 60; //update the seconds variable with no. of hours removed
minutes = Math.floor(seconds / 60);
seconds -= minutes * 60; //update the seconds variable with no. of minutes removed
//console.log(thisEl, thisEl.find(".timeRefDays"));
//conditional Ss
if (days == 1) { thisEl.find(".timeRefDays").text("day"); } else { thisEl.find(".timeRefDays").text("days"); }
if (hours == 1) { thisEl.find(".timeRefHours").text("hour"); } else { thisEl.find(".timeRefHours").text("hours"); }
if (minutes == 1) { thisEl.find(".timeRefMinutes").text("minute"); } else { thisEl.find(".timeRefMinutes").text("minutes"); }
if (seconds == 1) { thisEl.find(".timeRefSeconds").text("second"); } else { thisEl.find(".timeRefSeconds").text("seconds"); }
//logic for the two_digits ON setting
if(settings['format'] == "on") {
days = (String(days).length >= 2) ? days : "0" + days;
hours = (String(hours).length >= 2) ? hours : "0" + hours;
minutes = (String(minutes).length >= 2) ? minutes : "0" + minutes;
seconds = (String(seconds).length >= 2) ? seconds : "0" + seconds;

clearInterval(interval);
}
}
//run the function
countdown_proc();
//loop the function
interval = setInterval(countdown_proc, 1000);
}
// here you can create your Date instance any way you like:
const oneHourFromNow= new Date();
oneHourFromNow.setHours(oneHourFromNow.getHours() + 1);
const config = {
"date": oneHourFromNow.toString(),
"format": "off"
}
const callbackFunc = function() {console.log("Do something");}

javascript countdown from d:h:m:s

I'm new in javascript.
My PHP script returns a value in this format
d:h:m:s
Now I would like to have a countdown which is able to countdown each second from this.
I modified a countdown. This works once a time, after the countdown "ticks" each second it returns NaN all the time. Any idea what I do wrong?
$(document).ready(function() {
setInterval(function() {
$('.countdown').each(function() {
var time = $(this).data("time").split(':');
var timestamp = time[0] * 86400 + time[1] * 3600 + time[2] * 60 + time[3] * 1;
var days = Math.floor(timestamp / 86400);
console.log(time,timestamp);
var hours = Math.floor((timestamp - days * 86400) / 3600);
var minutes = Math.floor((timestamp - hours * 3600) / 60);
var seconds = timestamp - ((days * 86400) + (hours * 3600) + (minutes * 60))-1;
$(this).data("time",""+days+":"+hours+":"+minutes+":"+seconds);
if (hours < 10) {
hours = '0' + hours;
}
if (minutes < 10) {
minutes = '0' + minutes;
}
if (seconds < 10) {
seconds = '0' + seconds;
}
$(this).text(days + ':' + hours + ':' + minutes + ':' + seconds);
});
}, 1000);
})
</script>

<h1 class="countdown">02:03:05:59</h1>

As far as I can see you have 2 problems here:
after the first execution you change the pattern of the text you display in the h1. First you have 02:03:05:59. Then you want to write 02 days 03:05:58 into the tag. Next time you parse it, you get the error because you split at : and that does not work anymore as you have days instead of : as the seperator for the first part.
When calculating the minutes, you should also substract the days and not just the hours.
When you wan to keep the dd:hh:mm:ss format, you could do it like this:
$(document).ready(function() {
setInterval(function() {
$('.countdown').each(function() {
var time = $(this).text().split(':');
var timestamp = time[0] * 86400 + time[1] * 3600 + time[2] * 60 + time[3] * 1;
timestamp -= timestamp > 0;
var days = Math.floor(timestamp / 86400);
console.log(days);
var hours = Math.floor((timestamp - days * 86400) / 3600);
var minutes = Math.floor((timestamp - days * 86400 - hours * 3600) / 60);
var seconds = timestamp - days * 86400 - hours * 3600 - minutes * 60;
if (days < 10) {
days = '0' + days;
}
if (hours < 10) {
hours = '0' + hours;
}
if (minutes < 10) {
minutes = '0' + minutes;
}
if (seconds < 10) {
seconds = '0' + seconds;
}
$(this).text(days + ':' + hours + ':' + minutes + ':' + seconds);
});
}, 1000);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<h1 class="countdown">02:03:05:59</h1>

Your snippet goes from dd:hh:mm:ss to dd days, hh hours. So second time around, your tag contains non-parsable text.
I have changed it to something more precise. Something even MORE precise would be to give a timestamp in milliseconds in the future instead of something with seconds since it will take several seconds to render the page. If you round on minutes from the server, it would likely be better.
var aDay = 24*60*60*1000, anHour = 60*60*1000, aMin = 60*1000, aSec = 1000;
$(document).ready(function() {
$('.countdown').each(function() {
var time = $(this).data("time").split(':');
var date = new Date();
date.setDate(date.getDate()+parseInt(time[0],10))
date.setHours(date.getHours()+parseInt(time[1],10),date.getMinutes()+parseInt(time[2],10),date.getSeconds()+parseInt(time[3],10),0)
$(this).data("when",date.getTime());
});
setInterval(function() {
$('.countdown').each(function() {
var diff = new Date(+$(this).data("when"))-new Date().getTime();
var seconds, minutes, hours, days, x = diff / 1000;
seconds = Math.floor(x%60); x=(x/60|0); minutes = x % 60; x= (x/60|0); hours = x % 24; x=(x/24|0); days = x;
$(this).text(
days + ' day' +(days==1?", ":"s, ") +
hours + ' hour' +(hours==1?", ":"s, ") +
minutes + ' minute'+(minutes==1?", ":"s, ") +
seconds + ' second'+(seconds==1?".":"s.")
);
});
}, 500);

How to finished countdown to 0 second?

How to finished countdown to 0 second ?
When finished countdown it's will show 00days00hours00minutes01seconds
i want to show 0 second like this 00days00hours00minutes00seconds how can i do ?

Here you go
(function($) {

// trim zero
function trimZero(str) {
return parseInt(str.replace(/^0/g, ''));
}
// convert string to time
function getDiffTime(str) {
var m;
if ((m = /^(\d{4})[^\d]+(\d{1,2})[^\d]+(\d{1,2})\s+(\d{2})[^\d]+(\d{1,2})[^\d]+(\d{1,2})$/.exec(str))) {

day = trimZero(m[3]),
hour = trimZero(m[4]),
minute = trimZero(m[5]),
second = trimZero(m[6]);
return Math.floor((new Date(year, month, day, hour, minute, second).getTime() - new Date().getTime()) / 1000);
}
return parseInt(str);
}
// format time
function format(diff) {
var tmpl = options.tmpl, day, hour, minute, second;
day = /%\{d\}/.test(tmpl) ? Math.floor(diff / 86400) : 0;
hour = Math.floor((diff - day * 86400) / 3600);
minute = Math.floor((diff - day * 86400 - hour * 3600) / 60);
second = diff - day * 86400 - hour * 3600 - minute * 60;
day = ("00" + day).substr(-2);
hour = ("00" + hour).substr(-2);
minute = ("00" + minute).substr(-2);
second = ("00" + second).substr(-2);
tmpl = tmpl.replace(/%\{d\}/ig, day)
.replace(/%\{h\}/ig, hour)
.replace(/%\{m\}/ig, minute)
.replace(/%\{s\}/ig, second);
return tmpl;
}
// main
return this.each(function() {
var el = this,
diff = getDiffTime($(el).attr(options.attrName));
function update() {
if (diff < 0) {
if (options.afterEnd) {
options.afterEnd();
}
return;
}
$(el).html(format(diff));
setTimeout(function() {
diff--;
update();
}, 1000);
}
update();
});
};
})(jQuery);
$(function() {
$('.J_countdown2').countdown({
tmpl : '<span>%{d}</span>days<span>%{h}</span>hours<span>%{m}</span>minutes<span>%{s}</span>seconds'
});
});

diff <= -1
instead of
diff <= 0
in your update function
