'Tis the time of year when NORAD, the "bi-national U.S.-Canadian military organization responsible for the aerospace and maritime defense of the United States and Canada," turns its attention to tracking a certain visitor from the North Pole. The NORAD Tracks Santa website features a map showing where Santa has gone and NORAD also has an explanation of how Santa can work the way he does:

The fact that Santa Claus is more than 16 centuries old, yet does not appear to age, is our biggest clue that he does not work within time as we know it. His Christmas Eve trip may seem to take around 24 hours, but to Santa it may last days, weeks or even months in standard time. Santa would not want to rush the important job of distributing presents to children and spreading Christmas happiness everyone, so the only logical conclusion is that Santa functions within a different time-space continuum than the rest of us do.

There are even more videos, such as him flying with the reindeer over the Great Wall...or into space to visit the International Space Station.

Santa will have eaten lots of cookies and milk by the time he gets here!
