Epiphany, the Feast of The Three Kings. Epiphany is celebrated 12 days after Christmas on 6th January (or January 19th for some Orthodox Church who have Christmas on 7th January) and is the time when Christians remember the Wise Men (also sometimes called the Three Kings) who visited Jesus.
The Roman Catholic and Protestant churches emphasize the visit of the Magi when they celebrate the Epiphany. The Eastern Orthodox churches focus on Jesus’ baptism. Epiphany is one of the oldest Christian feasts. It was celebrated since the end of the second century, before the Christmas holiday was established.
