Little Christmas or more commonly known as the Fest of the 3 Kings or Epiphany is a common celebration across the world. Liturgically in some countries, the Solemnity of the Epiphany is celebrated on the Sunday after the Epiphany, however it is still on the calendar as January 6th, in some countries it is still a Holy Day of Obligation to attend on that day (and in fact in the Old Rite Calendar, it would be, as no feasts in the Old Calendar are moved to Sunday), countries like the US and the UK the Bishops conference has moved it to the Sunday after.In many communities it is called Little Christmas in which smaller gifts are given to celebrate the Three Kings locating the infant Jesus.
Twelfth Nights a festival in some branches of Christianity marking the coming of the Epiphany and concluding the Twelve Days of Christmas. It is defined by the Shorter Oxford English Dictionary as “the evening of the fifth of January, preceding Twelfth Day, the eve of the Epiphany, formerly the last day of the Christmas festivities and observed as a time of merrymaking”. However, there is currently some confusion as to which night is Twelfth Night: some count the night of Epiphany itself (sixth of January) to be Twelfth Night One source of this confusion is the Medieval custom of starting each new day at sunset, so that Twelfth Night precedes Twelfth Day.
A recent belief in some English-speaking countries holds that it is unlucky to leave Christmas decorations hanging after Twelfth Night, a belief originally attached to the festival of Candlemas (2 February).
