				var kickoff = new Date(2015, 0, 3, 10, 30, 0, 0)
					var diff = kickoff - new Date()
					var d = Math.floor(diff/1000.0/60.0/60.0/24.0)
					diff -= d * 1000 * 60 * 60 * 24
					var h = Math.floor(diff/1000.0/60.0/60.0)
					diff -= h * 1000 * 60 * 60
					var m = Math.floor(diff/1000.0/60.0)
					diff -= m * 1000 * 60
					var s = Math.floor(diff/1000)
					dDiv.innerHTML = d
					hDiv.innerHTML = h
					mDiv.innerHTML = m
					sDiv.innerHTML = s
					document.title = d + " Days Until Kickoff"

Here's how I did it, just a little bit easier to read and modify. The -= vs %= difference for the calculation is interesting.
