Women's Christmas or Nollaig na mBan in the Irish language, is one of the traditional names in Ireland for January 6. It is so called because of the tradition (still surviving, though only just) of Irish men taking on all the household duties on that day and giving their spouses a day off. It is also called Little Christmas and/or Twelfth Day and is the traditional end of the Christmas season and last day of the school holidays.
