Celebrated annually Dec. 25, Christmas honors the birth of Jesus of Nazareth. Modern customs of the holiday include gift-giving, church activities, and various decorations – including the Christmas tree, lights, mistletoe, nativity scenes, and holly. Children also identify Santa Claus as a popular figure who brings gifts at Christmas. Because gift-giving and several other aspects of the holiday involve economic activity, Christmas has become a major event for many retailers.
Along with Christmas, several other holidays are celebrated by our professionals in December, including: Hanukkah, Kwanzaa, and Id-ul-Zuha (celebrated earlier this month).
Gee, thanks for the "also-ran" mention!
