jQuery - Count down to specific time -

i want count down specific time on specific date. have count specific date, @ 12:00am. need count down 3:00pm. possible?

what got now:

var date = new date(2015, 6, 31); // !!! maanden beginnen bij 0, dus januari 0. var = new date(); var diff = (date.gettime()/1000) - (now.gettime()/1000); 

thanks help!

edit:

apparently simpler thought ...

i had do

var date = new date(2015,6, 31, 15,00); 

do mean counting seconds? assume seconds difference between 2 dates. example should this:

var date = new date(2015, 6, 31); // !!! maanden beginnen bij 0, dus januari 0. var = new date(); var diff = (date.gettime()/1000) - (now.gettime()/1000); var count=diff; var counter=setinterval(timer, 1000); //1000  run every 1 second  function timer() {   count=count-1;   if (count <= 0)   {      clearinterval(counter);      return;   }   document.getelementbyid("timer").innerhtml=count + " secs"; // watch spelling } 

you can show time this:

<span id="timer"></span> 

i hope can in want do.
