Christmas Season
The entire Christmas Cycle is a crescendo of Christ's manifesting Himself as God and King -- to the shepherds, to the Magi, at His Baptism, to Simeon and the prophetess, Anna (Luke 2). The days from the Feast of the Nativity to the Epiphany are known as "The Twelve Days of Christmas," with Christmas itself being the first day, and Twelfth night -- 5 January -- being the last of the twelve days. Christmastide liturgically ends on 13 January, the Octave of the Epiphany and the Baptism of Christ (at which time the season of Time After Epiphany begins).
But Christmas doesn't end spiritually -- i.e., the celebration of the events of Christ's life as a child don't end, and the great Christmas Cycle doesn't end -- until Candlemas on 2 February and the beginning of the Season of Septuagesima.
