Christmas is an annual holiday that celebrates the birth of Jesus. Christmas festivities often combine the commemoration of Jesus' birth with various customs, many of which have been influenced by earlier winter festivals. Traditions include the display of Nativity scenes, Holly and Christmas trees, the exchange of gifts and cards, and the arrival of Father Christmas (Santa Claus) on Christmas Eve or Christmas morning. Popular Christmas themes include the promotion of goodwill, compassion, love, acceptance, kindness, generosity, excitement and peace.
