I have searched the web but all the ones readily available are where you specificy a date and it counts down to that date. What I need is something which will simply count d
I also made a count-down clock but with html5 canvas. Feel free to use it if you like it. (Run the code snipet below)

<p>JS WlCounter class counts-down to the event starting and ending date with color change on reaching the first one. After event start date is reached it changes the color to green and start count-down to events end date (if end date was specyfied and is more then curent time). So when event is ended, counter gets graied out and set 0</p>

I think you're looking for something like this.
Something like this should do the trick. I'm bored and decided to do it myself instead of Googling. Just set the minutes and seconds at the top and change the call to countdown inside the onload to the id of the element you want it to update.

jCounter is a plugin that also accepts custom values to display any countdown you want
I have made a simple countdown you can use.
It is generating the format:
DAYS X, HOURS X, MINUTES X, SECONDS X
The JS:
countIt();
function countIt(){
year = 2013;
month = 05;
day = 28;
hours = 12;
minutes = 00;
seconds = 00;
setTimeout(function(){
endDate = new Date(year, (month - 1), day, hours, minutes, seconds, 00);
thisDate = new Date();
thisDate = new Date(thisDate.getFullYear(), thisDate.getMonth(), thisDate.getDate(), thisDate.getHours(), thisDate.getMinutes(), thisDate.getSeconds(), 00, 00);
var daysLeft = parseInt((endDate-thisDate)/86400000);
var hoursLeft = parseInt((endDate-thisDate)/3600000);
var minutsLeft = parseInt((endDate-thisDate)/60000);
var secondsLeft = parseInt((endDate-thisDate)/1000);
seconds = minutsLeft*60;
seconds = secondsLeft-seconds;
minutes = hoursLeft*60;
minutes = minutsLeft-minutes;
hours = daysLeft*24;
hours = (hoursLeft-hours) < 0 ? 0 : hoursLeft-hours;
days = daysLeft;
startCount(days, hours, minutes,seconds);
}, 1000);
}
function startCount(days, hours, minutes, seconds){
document.getElementById("counter").innerHTML="DAYS "+days+", HOURS "+hours+", MINUTES "+minutes+", SECONDS: "+seconds;
countIt();
}
The HTML:
<div id="counter"></div>
Click here to see it live
um, why not just use this:
<div id="countdown">countdown displayed here</div>
<script type="text/javascript">
$(document).ready(function() {
//time to count down
hoursToGo = 0;
minutesToGo = 27;
secondsToGo = 43;
var startTime = new Date();
var endTime = new Date();
endTime.setHours(
startTime.getHours() + hoursToGo,
startTime.getMinutes() + minutesToGo,
startTime.getSeconds() + secondsToGo,
startTime.getMilliseconds()
);
//function to update counter
function update(){
var currentTime = new Date();
var remainingTime = new Date();
remainingTime.setTime(endTime.getTime()-currentTime.getTime());
$("#countdown").text(remainingTime.getHours()+":"+remainingTime.getMinutes()+":"+remainingTime.getSeconds());
//call itself every second
setTimeout(update,1000);
}
//start the countdown
update();
});
</script>
EDIT As an added thought, you could implement this over multiple pages by passing the end time onto the next page as the value of a hidden form element. Or at least thats what i am going to do with it ;-)
