What date is the Twelfth Day of Christmas?
5th January – (Ephiphany starts on 6th January). The Twelve Days of Christmas is probably the most misunderstood part of the church year among Christians who are not part of liturgical church traditions. Contrary to much popular belief, these are not the twelve days before Christmas, but in most of the Western Church are the twelve days from Christmas until the beginning of Epiphany (January 6th; the 12 days count from December 25th until January 5th).
