Santa’s made his list and he’s checking it twice, but for most good little boys and girls there’s nothing more fun than tracking Santa on Christmas Eve.

This year, the North American Aerospace Defense (NORAD) and Google have launched interactive Santa tracking sites, which include a Christmas countdown and games.

Google’s version of the tracker, launched on the first day of the month.

“Starting today, the elves are back on the clock in the North Pole, and through the month of December, you can join the elves as they unlock a new project or game each day in preparation for Santa’s annual journey around the world,” Santa Launch Strategist Sandy Russell said on Google’s blog.

A Christmas tradition in many households for years, NORAD has launched its Santa Tracker Countdown, which allows families to know to the second when the Jolly Ole Elf and his magical reindeer will take flight.
