Christmas is a Christian festival that celebrates the birth of Jesus Christ, who Christians believe was the son of God. For most people, it takes place every year on 25 December – the day that the Roman Catholic Church chose to mark Jesus' birthday. But, in fact, no one actually knows the exact date Jesus was born! Christmas is an annual festival celebrated on December 25th (Friday in 2026) to commemorate the birth of Jesus Christ, serving as both a sacred religious holiday for Christians and a widespread cultural, secular celebration. Key traditions include exchanging gifts, decorating trees, attending church services, and gathering for meals.
