This post is describing how to create countdown timer using JQuery.If you already have a knowledge of java script time,date functions this is very easy job.OK.We’ll see how to create countdown timer using JQuery.

1-First you must load the JQuery library file.
2-This is the html content.

3-This is the countdown function.

var timezone = new Date()
var gmtHours = -timezone.getTimezoneOffset()/60;
month		 = --month;
dateFuture   = new Date(year,month,day,hour-gmtHours,min,sec);
function countProcess(){
        dateNow = new Date();
        amount  = dateFuture.getTime() - dateNow.getTime()+5;
        delete dateNow;
        /* time is already past */
        if(amount < 0){
                output ="
0
" +
						"
0
" +
						"
0
" +
						"
0
" ;
                $('#countbox').html(output);
        }
        /* date is still good */
        else{
                days=0; hours=0; mins=0; secs=0; output="";
                amount = Math.floor(amount/1000); /* kill the milliseconds */
                days   = Math.floor(amount/86400); /* days */
                amount = amount%86400;
                hours  = Math.floor(amount/3600); /* hours */
                amount = amount%3600;
                mins   = Math.floor(amount/60); /* minutes */
                amount = amount%60;
                secs   = Math.floor(amount); /* seconds */
                output="
" + days +"
" +
						"
" + hours +"
" +
						"
" + mins +"
" +
						"
" + secs +"
" ;
				$('#countbox').html(output);
                setTimeout("countProcess()", 1000); // call to the function every seconds
        }
}

4-How to call to this function and set end date.

//pass the parameters
year = 2012; month = 12; day = 25;hour= 16; min= 0; sec= 0;
//call to the function start
$(function(){
	countProcess();
});

Put this all together.

That’s only.
