Christmas is a holiday celebrated on December 25th each year that originated in ancient times as a winter solstice celebration. The name "Christmas" derives from the Old English term "Cristes Maesse," which means "Mass of Christ." The holiday has since evolved into a celebration of Jesus' birth, and has become a time of giving and family gatherings. In many cultures, Christmas also marks the start of the new year, symbolizing a time of renewal and hope.
