why did christmas start

Christmas is a holiday celebrated on December 25th each year, and it is based on the birth of Jesus Christ. The holiday is observed by many Christians and non-Christians alike and is associated with the traditions of gift-giving, decorations, and family gatherings. The origins of Christmas can be traced back to the Roman Empire, where a festival known as Saturnalia was celebrated during the winter solstice. As Christianity spread, the holiday of Christmas was created to commemorate the birth of Jesus Christ.
