You also can follow Santa's progress on the interactive map above.
According to NORAD, Santa could get to Woodstock as early as 8:30 p.m. and should be gone by midnight, give or take a few reindeer pit stops.
To get the latest updates on his progress, call 877-HINORAD, and a friendly volunteer, usually from the armed forces, will help you out. (If you get a soldier, sailor, airman or Marine, be sure to offer thanks for serving our country so you can stay on Santa's good-child list.)
What treats will Santa find when he gets to your house?
While you wait, check out the games and activities at the Countdown Village.
And as the big guy says, "Merry Christmas to all, and to all, a good night."
