If you want to find out exactly where Santa is on Christmas Eve, NORAD (North American Air Defense Command) tracks him by radar every year as he makes his way around the world.
It all started in 1955 when an advertisement for a Santa Hotline included a misprinted telephone number. Instead of reaching Santa, children who called the number reached NORAD's (then called CONAD) director of operations. When it became clear what was going on, the CONAD staff checked to see if there was any sign of Santa on the radar. There was! After that, children who called were given an update on Santa's location.
Today, you can track Santa on NORAD's website. For his up to the minute location, visit www.noradsanta.org.
