Epiphany is the celebration of God revealing Himself in human form. Celebrated on January 6, primarily commemorates the visitation of the Magi to the infant Jesus. Eastern churches also celebrate the Epiphany, but it is primarily a celebration of the Baptism of our Lord. It has been observed since at least 361. In some Eastern churches it is called the "Theophany".
At first, it was a celebration of all aspects of the Incarnation and all early events in the life of Christ up to the Wedding at Cana. By 385, it was celebrated as an Octave among western-rite Christians. The Octave was removed as part of the Roman Calendar reforms of 1970.
In countrioes where the feast is a Holy Day of Obligation, it is celebrated on January 6. If it is not a Holy Day of Obligation, then it is celebrated on the first Sunday after January 1.
