Christmas
People celebrate Christmas in many places around the world. Some people celebrate Christmas as a religious holiday. In some places, Christmas is a time of celebration for Christians and non-Christians alike. Christmas traditions are different in different countries. However, they almost always include a feast; giving gifts or cards; and enjoying church or public festivities, like singing Christmas carols and songs. Christmas is not limited to Christianity. The idea of Santa Claus is based on Saint Nicholas, a 4th-century Christian saint of Greek origin.
