Christmas or Christmas Day is an annual holiday that marks the traditional birthdate of Jesus of Nazareth. Christmas combines the celebration of Jesus' birth with various other traditions and customs, many of which were influenced by ancient winter festivals such as Yule[1] and Saturnalia. Christmas traditions include the display of Nativity scenes and Christmas trees, the exchange of gifts and cards, and the arrival of Santa Claus on Christmas Eve. Popular Christmas themes include the promotion of goodwill, giving, compassion, and quality family time.
