Tjugondag jul ("Twentieth Day Yule"), or Tjugondag Knut ("Twentieth Day Knut"), or Knutomasso, or Nuutinpäivä ("Knut's Day"), in English Saint Knut's Day, is a traditional festival celebrated in Sweden and Finland on 13 January. It is not celebrated on this date in Denmark (the Knut day was moved in Sweden, not in Denmark) despite being named for the Danish prince Canute Lavard, and later also associated with his uncle, Canute the Saint, the patron saint of Denmark. Christmas trees are taken down on Tjugondag jul, and the candies and cookies that decorated the tree are eaten. In Sweden, the feast held during this event is called a Knut's party (Julgransplundring, literally "Christmas tree plundering").
Canute Lavard (Knut Levard in Swedish) was a Danish duke who was assassinated by his cousin and rival Magnus Nilsson on 7 January 1131 so he could usurp the Danish throne. In the aftermath of his death there was a civil war, which led to Knut being later declared a saint, and 7 January became Knut's Day, a name day.
As his name day roughly coincided with Epiphany (the "thirteenth day of Christmas"), Knut's Day and Epiphany were conflated to some degree. In 1680, Knut's Day was moved to 13 January and became known as tjugondag Knut or tjugondedag jul (the "twentieth day of Knut/Christmas").
On Nuutinpäivä, a tradition has been observed which is somewhat analogous to the modern Santa Claus, where young men dressed as goats (Finnish: Nuuttipukki) would visit houses. Usually the dress was an inverted fur jacket, a leather or birch bark mask, and horns. Unlike Santa Claus, Nuuttipukki was a scary character (cf. Krampus). The men dressed as Nuuttipukki wandered from house to house, came in, and typically demanded food from the household and especially leftover alcoholic beverages. In Finland the Nuuttipukki tradition is still kept alive in areas of Satakunta, Southwest Finland and Ostrobothnia. However, nowadays the character is usually played by children and now involves a happy encounter.
