Christmas is the celebration of the birth of Jesus Christ.
There are many theories concerning the new star, the wise men, and other aspects of the Christmas Holiday.
Attached is a Powerpoint presentation on St Nicholas, also known as Santa Claus. In Dutch, he is referred to as Sinterklaas, which is similar to Saint=Santa, and Klaas=shortened form of Nicolas. While not directly related to the birth of the Savior, the story of St Nicholas is still an interesting sidebar at Christmas time.
