Hi,
   I'd like to create a countdown timer that shows the number of days, hours, minutes and seconds till the next Friday. Is it possible to do this with javascript?

I imagine the only difficulty could be finding the date of the next Friday, but I could add this to a PHP variable if it helps.

Any help would be appreciated.

Thanks

Here is the script:

function countdownNextFriday() {
      var today = new Date();
      var todayOfWeek = today.getDay();
      var daysToNextFriday = (todayOfWeek >= 5?12:5) - todayOfWeek;

      var nextFriday = new Date(today.getTime() + (daysToNextFriday * 86400000));
      nextFriday.setHours(0); nextFriday.setMinutes(0); nextFriday.setSeconds(0); nextFriday.setMilliseconds(0);

      var diff = nextFriday.getTime() - today.getTime();      
      countdown.innerHTML =
      "<p> Countdown to Next Friday: " +
      Math.floor(diff/(24 * 60 * 60 * 1000)) + " days " +
      Math.floor(diff/(60 * 60 * 1000) % 24) + " hours " +
      Math.floor(diff/(60 * 1000) % 60) + " minutes " +
      Math.floor(diff/1000 % 60) + " seconds "
       + "</p>";
}
