Father Christmas is getting ready for his busiest night of the year and you can track him and his reindeer on his way to Chester using Norad's Track Santa.
Track Santa picks up Santa's sleigh radar as he leaves the North Pole and delivers presents around the world on Christmas Eve.
It shows you how many gifts he's delivered, where he was last seen and where he is headed for next.
All you have to do is visit Norad's Track Santa on Christmas Eve so you can keep an eye on his whereabouts. But remember that he won't visit homes if anyone is awake and it's best to leave him some mince pies and milk (or maybe whisky, ask mam and dad first).
Who tracks Santa?
Track Santa is currently run by the North American Aerospace Defense Command, also known as NORAD but Santa has been tracked from 1955.
It started when a business misprinted the telephone number for children to call Santa, and instead of reaching Father Christmas, the phone number put kids through to the operations "hotline" for Continental Air Defense Command (CONAD).
Colonel Harry Shoup was the Director of Operations at the time so he asked his staff to check the radar for indications of Santa making his way from the North Pole.
Then in 1958 NORAD took on the tradition of tracking Santa and they've been doing it ever since.
