The Twelve Days of Christmas and the associated evenings of those twelve days (Twelve-tide), are the festive days from the evening after Christmas day (December 25) through Epiphany on (January 6). December 26 (Boxing Day / St. Stephen's Day) is the first day of Christmas, then December 27 is the second day of Christmas, and so on until January 6 which is the 12th day of Christmas. Christmas day, December 25, is therefore not one of the twelve days of Christmas. The associated evenings of the twelve days begin on the evening before the specified day. Thus, the first-night is December 25–26, and Twelfth-night is January 5–6.
