Little Christmas (Irish: Nollaig Bheag) is one of the traditional names in Ireland for January 6, more commonly known in the rest of the world as the Celebration of the Epiphany. It is so called because it was the day on which Christmas Day was celebrated under the Julian calendar, before the adoption of the Gregorian calendar. It is the traditional end of the Christmas season and the last day of the Christmas holidays for both primary and secondary schools in Ireland.

In the Scottish Highlands the term Little Christmas (Scottish Gaelic Nollaig Bheag) is applied to Hogmanay, New Year's Day, also known as L Challuinn, or L na Bliadhna ire, while Epiphany is known as L Fill nan Rgh, the feast of the King.

The name Little Christmas is also found other languages including Slovene, Galician and Ukrainian.

Women's Christmas:

Little Christmas is also called Women's Christmas (Irish: Nollaig na mBan), and sometimes Women's Little Christmas. The tradition, still very strong in Cork and Kerry is so called because of the Irish men taking on all the household duties for the day. Most women hold parties or go out to celebrate the day with their friends, sisters, mothers, and aunts. Bars and restaurants serve mostly women and girls on this night. Children often buy presents for their mothers and grandmothers.

The tradition is not well documented, but one article from The Irish Times (January 1998), entitled On the woman's day of Christmas, describes both some sources of information and the spirit of this occasion.
