Background
Many Christians celebrate the birth of Jesus of Nazareth in Bethlehem on December 25, although the true date and year of his birth is unclear. The tradition of celebrating his birth at the end of December may come from the widespread European tradition of celebrations around the winter solstice. Christians who follow the Eastern Orthodox tradition celebrate the birth of Jesus on January 7, while it is marked on January 6 by the Armenian Apostolic Church.
Symbols
There are many symbols of Christmas. These include images of baby Jesus and the Holy family in the stable, stars and Christmas trees. Another important symbol of Christmas is Santa Claus. This is a mythical figure with origins in European, particularly British, Dutch and German, cultures. He is a jolly man who wears a red suit, has a long white beard, lives at the North Pole and travels in a sleigh pulled by reindeer. On Christmas Eve, he travels to the homes of children and leaves them presents in Christmas stockings or under the Christmas tree.
The North American Aerospace Defense Command (NORAD), which monitors and controls the aerospace above the United States and Canada, even "monitors" Santa's movements during November and December. Images and models of Santa Claus and actors playing his role can be seen in many places in the lead up to Christmas.
