Christmas does have its roots in pagan traditions, but it has evolved over the centuries to become a holiday that is centered around Christian beliefs. The celebration of Christmas as a religious holiday began in the early Middle Ages, when the church began to observe December 25th as the birth date of Jesus Christ. Over time, the holiday became associated with other traditions and customs, such as gift-giving, Santa Claus, and the exchange of Christmas cards. While there are still elements of pagan tradition in Christmas, it is ultimately a holiday that is centered around the Christian belief in the birth of Jesus Christ.
