Its Twelfth Night.

Twelfth Night (also known as Epiphany Eve) is a festival in some branches of Christianity that takes place on the last night of the Twelve Days of Christmas, marking the coming of the Epiphany. 

Different traditions mark the date of Twelfth Night as either 5 January or 6 January, depending on whether the counting begins on Christmas or 26 December.

A superstition in some English-speaking countries suggests it unlucky to leave Christmas decorations hanging after Twelfth Night.

January 6, which is 12 days after Christmas in the Gregorian calendar, marks end of the Christmas holidays.

It means “manifestation” or “showing forth.” It is also called Theophany (“manifestation of God”), especially by Eastern Christians. Epiphany refers not only to the day itself but to the church season that follows it.

It commemorates the first two occasions on which Jesus’ divinity, according to Christian belief, was manifested: when the three kings (also known as wise men or Magi) visited infant Jesus in Bethlehem, and when John the Baptist baptized him in the River Jordan. 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. Like other Christian seasons, the church appropriated Epiphany from an old pagan festival.
