Just change the line:
Code:
var futuredate=new cdtime("countdowncontainer", "March 23, 2009 18:25:00")
to:
Code:
var futuredate=new cdtime("countdowncontainer", "July 28, 2008 23:59:59")
and then it will countdown to 'July 28, 2008 23:59:59'....
Obviously you'll have to edit the code in the <head> as it is hard coded to say "left until March 23, 2009 18:25:00".
I hope that makes sense...
[edit] Obviously I'm a bit late, as it's the 28th! lol but it will still work for any date in the future!
