Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. It is a feast central to Christianity. In the liturgical year, preparation for Christmas begins on the First Sunday of Advent (the fourth Sunday before), and it is followed by Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night.
