Official NORAD Tracks Santa
NORAD Tracks Santa is an annual Christmas-themed program in which North American Aerospace Defense Command (NORAD) simulates[1] the tracking of Santa Claus, who is said to leave the North Pole to travel around the world on his mission to deliver presents to children every year on Christmas Eve.[2][3][4] The program starts on December 1, but the actual Santa-tracking simulation starts at midnight annually on December 24. It is a community outreach function of NORAD, and has been held annually since 1955. wikipedia
