Epiphany (Greek for "appearance" or "revelation"), is a Christian feast day which celebrates the "shining forth" or revelation of God in human form in the person of Jesus Christ. The feast falls on January 6. Western Christians commemorate the visitation of the Magi to the child Jesus on this day, i.e., his manifestation to the Gentiles. Eastern Christians commemorate the baptism of Jesus in the Jordan River, his manifestation as the Son of God to the world. It is also called Theophany ("manifestation of God"), especially by Eastern Christians.
