The Epiphany of the Lord
In Epiphania Domini
Epiphany, also known as Theophany in Eastern Christian tradition, is a Christian feast day commemorating the visit of the Magi, the baptism of Jesus, and the wedding at Cana.
In Western Christianity, the feast commemorates principally (but not solely) the visit of the Magi to the Christ Child, and thus Jesus Christ's physical manifestation to the Gentiles. It is sometimes called Three Kings' Day, and in some traditions celebrated as Little Christmas. Moreover, the feast of the Epiphany, in some denominations, also initiates the liturgical season of Epiphanytide.
Eastern Christians, on the other hand, commemorate the baptism of Jesus in the River Jordan, seen as his manifestation to the world as the Son of God, and celebrate it as the Feast of the Epiphany or of the Theophany. The traditional site of the ministry of John the Baptist is in Al-Maghtas in Jordan, with the baptism of Jesus once marked in Byzantine times by a cross in the middle of the Jordan River, between the Jordanian site and Qasr al-Yahud in the West Bank.
