I'm trying to get this script to countdown until halloween I've got:

Code:
		$(function () {
			var liftoffTime = new Date(2010, 10, 31, 00, 00, 00,00);
			$('#counter').countdown({until: liftoffTime, 
		    layout: '{dn} {dl}, {hn} {hl}, {mnn} {ml}, {snn} {sl}'});
	});
but when I check it live it says "65 DAYS, 9 HOURS, 37 MINUTES, 54 SECONDS" when its actually 34 days? Any ideas?
