Christmas Day is the first of the Twelve Days of Christmas. The period is viewed by Christians as the amount of time it took the three magi, or wise men, to travel to Bethlehem for the Epiphany, the revelation of Jesus Christ as the savior and the son of God ("epiphany" is from the Greek word for "revelation").
While there's a consensus on what Christmas commemorates, what the Epiphany honors varies between churches and cultures. Some churches believe it's the day of Christ's baptism, while others celebrate it as the day the three magi visited Jesus with gifts.
But there are also differences on when the twelve days are celebrated. Western churches, for example, celebrate Christmas on the Dec. 25, the Epiphany on the Jan. 6, and the period in between as the 12 days and nights of Christmas. Other cultures, however, have different customs.
Although most in the Eastern Orthodox Church now adhere to the Western calendar, those in the Greek Orthodox Church still use a different religious calendar, celebrating Christmas on Jan. 7, and the Epiphany on Jan. 19. Some Latin-American cultures celebrate the Epiphany as Three Kings Day, giving gifts on Jan. 6 instead of Christmas. Other cultures will give one gift per day from Christmas to the Epiphany. This tradition has never really caught on in America, where the celebration of Christmas Eve and Christmas Day is most common [source: Bratcher].
The Twelfth Night, often celebrated on the night of Jan. 5, is considered the end of the Christmas season, before the Epiphany the following day. The Twelfth Night was a time for feasting in England (partly inspired by Shakespeare's play of the same name) in centuries past. Some cultures, like the French and Spanish, celebrate the Feast of the Epiphany with a king's cake, a coffee cake with purple, green and yellow icing to commemorate the visit by the magi to the Christ child. In western cultures, the King's Cake is associated with Mardi Gras, and the season of Carnival [source: Burnett]. Churches also vary in their celebration of the Epiphany; some Protestant churches celebrate it for an entire season, lasting until the season of Lent, while many Catholics celebrate it as a single day.
But just because the song is associated with the holiday season, that doesn't mean you can't sing it the rest of the year. For more information about all things Christmas, visit the next page.
