Western Europe celebrated Christmas, December 25, as the holiest day of the season... but Eastern Europe celebrated Epiphany, January 6, recalling the Wise Men's visit and Jesus' baptism. It could not be decided which day was holier, so the Council made all 12 days from December 25 to January 6 "holy days" or "holidays," These became known as "The Twelve Days of Christmas."»
