The Epiphany is a Christian feast which is always celebrated on the 6th of January. It commemorates the birth of Jesus when he was visited by the three kings, Balthazar, Melchior and Caspar. They each brought gifts for baby Jesus. Those gifts were Gold, Frankincense and Myrrh. Another name for the three kings was Magi which means wise men.
The three kings had been following a star in the east which would lead to the birth place of Jesus, who would be called the king of the Jews. When King Herod heard this news he was jealous for he wanted to be the main king around. He asked the Magi to inform him as soon as they had discovered the birth place of Jesus so that he could worship him. When the Magi found Jesus and his mother Mary they were thrilled and full of Joy. However they were warned in a dream to return home by a different road and to avoid any contact with Herod, who was determined to kill Jesus.
Many countries consider this event to be the real Christmas. Many Eastern Christians, such as in Greece and Russia think of January 6th as Christmas Eve.
