It's that time of year again; Santa Claus is coming to town.
After a year of gruelling work in the North Pole ensuring he has gifts for all the children in the world, Father Christmas will soon begin his annual trek around the globe.
With just a single night to get to everyone's homes, the big man in red and his faithful reindeer move at a lightning speed.
Here's how you can track where he is:
NORAD
The North American Aerospace Defence Command uses a radar called the North Warning system with 47 installations across the north of Canada and Alaska. The radar is continuously checking to see if Santa has left his home and lets us know when he has lifted off.
A combination of satellites and jet fighters then track his movements around the world.
NORAD has been tracking Santa since 1955, and will be kicking off this year's tracker on Christmas Eve.
As we await the big day, Google has a load of interactive games and activities to keep keen Santa-watchers busy - from Elf Jetpack to Snowball Storm, it can be a lot of fun.
The kids can even learn what Santa is called in different languages.
SantaUpdate
Dubbing itself as the "original Santa tracker online", SantaUpdate allows you to see a test flight just to make sure everything is working for December 25.
The team has also written several fun 'news' releases, with headlines like 'Tracker Elves Number More Than 40 million'.
ReindeerCam
This isn't technically a Santa tracker, but boasts to be a live video feed of "Santa's official reindeer". All going well, when the reindeer disappear, it should mean they are out hauling Saint Nick around.
SantaTrackerApp
Described as having the "cutest setup" of any tracker and being "simple" for kids, the Santa Tracker mobile application shows where Santa Claus is and what he is up to.
It also provides a rough estimate of how long it'll be until the big man in red arrives at your house.
WeatherWatch
From 1pm on Christmas Eve, WeatherWatch's radar navigation system will track Santa's progress around the world.
He's expected to leave the North Pole with his team of reindeer around lunchtime before heading south to New Zealand then beyond!
