Christmas also referred to as
Christmas Day or
Christmastide , is an annual
holiday celebrated on December 25 that marks and honors the birth of
Jesus of Nazareth. His birth, which is the basis for the
Anno Domini system of dating, has been determined by modern historians as
having occurred between 7 and 2 BC. The date of celebration is not thought to be Jesus' actual date of birth, and may have been chosen to coincide with
ancient Roman solar festivals that were held on December 25.
