Epiphany, also Theophany, Denha, Little Christmas, or Three Kings' Day, is a Christian feast day that celebrates the revelation of God incarnate as Jesus Christ. In Western Christianity, the feast commemorates principally (but not solely) the visit of the Magi to the Christ Child, and thus Jesus' physical manifestation to the Gentiles. Moreover, the feast of the Epiphany, in some Western Christian denominations, also initiates the liturgical season of Epiphanytide. Eastern Christians, on the other hand, commemorate the baptism of Jesus in the Jordan River, seen as his manifestation to the world as the Son of God. Qasr el Yahud in the West Bank, and Al-Maghtas in Jordan on the east bank, is considered to be the original site of the baptism of Jesus and the ministry of John the Baptist.
Popular Epiphany customs include Epiphany singing, chalking the door, having one's house blessed, consuming Three Kings Cake, winter swimming, as well as attending church services. It is customary for Christians in many localities to remove their Christmas decorations on Epiphany Eve (Twelfth Night), although those in other Christian countries historically remove them on Candlemas, the conclusion of Epiphanytide. According to the first tradition, those who fail to remember to remove their Christmas decorations on Epiphany Eve must leave them untouched until Candlemas, the second opportunity to remove them; failure to observe this custom is considered inauspicious.
