Saint Lucia Day (mainly in Scandinavia)

Saint Lucy's Day, also called the Feast of Saint Lucy, is a Christian feast day observed on 13 December. The observance commemorates Lucia of Syracuse, an early-fourth-century virgin martyr under the Diocletianic Persecution. According to legend, she brought food and aid to Christians hiding in the Roman catacombs, wearing a candle-lit wreath on her head to light her way, leaving both hands free to carry as much food as possible. Because her name means "light" and her feast day had at one time coincided with the shortest day of the year prior to calendar reforms, it is now widely celebrated as a festival of light. Falling within the Advent season, Saint Lucy's Day is viewed as a precursor of Christmastide, pointing to the arrival of the Light of Christ in the calendar on 25 December, Christmas Day.

Scandinavia is a subregion of northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. Scandinavia most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula. In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities.

December 13 is the 347th day of the year in the Gregorian calendar; 18 days remain until the end of the year.
