Christmas is celebrated annually on December 25th and commemorates the birth of Jesus Christ. The earliest historical evidence of Christmas being celebrated on this date comes from Rome in the 4th century AD. While Christmas began as a Christian religious holiday, it has also become a secular winter celebration embraced by non-Christians for its tradition of gift-giving, decorating trees, and family gatherings. People celebrate Christmas for various reasons including to honor the birth of Jesus, enjoy time off during the holiday season, allow children to receive gifts and believe in Santa Claus, and mark the winter solstice.
