The Christmas season in the Catholic Church lasts for 12 days, beginning on December 25th and ending on January 6th, which is also known as the Epiphany. This period is also known as Christmastide or the Christmas season, and it's a time of celebration, reflection, and worship, with special liturgical services and celebrations taking place throughout the season. The 12 days of Christmas are traditionally a time of joy and celebration, filled with music, food, and fellowship, and they also serve as a reminder of the true meaning of Christmas, which is the birth of Jesus Christ.
