Christmas celebrates the birth of Jesus Christ. For modern Christians it also starts a 12-day Christmas season that begins on December 25th and ends on January 5th. Churches celebrate Christmas with services on Christmas Eve and often midnight masses.
While the holiday is religious in origin, many cultures, even those without Christian ideologies, celebrate this holiday. This celebration often centers around Santa Claus, a mythical figure dressed in a red suit, based on Saint Nicholas. Tradition has it that on Christmas morning, Santa brings gifts for children who have been good and coal for those who have been naughty.
