Christmas is a holiday that is celebrated every year on December 25th. It is an important holiday in many countries around the world, especially in the United States and Europe. The holiday commemorates the birth of Jesus Christ, who is believed by Christians to be the son of God. According to the Christian bible, Jesus was born in a stable in Bethlehem over 2,000 years ago. He was born to Mary and Joseph, who were traveling to Bethlehem for a census. The birth of Jesus was announced by a group of angels, who appeared to shepherds in the fields nearby. Today, Christmas is celebrated with many traditions, including gift-giving, decorating Christmas trees, and attending church services.
