December 13 is named after saint Lucy – Sankta Lucia- , and celebrated with processions of singing white dressed girls, each with a candle in her hand. The Lucia brude had 4 candles in a wreath on her head. The tradition with Lucia procession came to Denmark from Sweden, around 1944. In Sweden they have documents telling about Lucia in 1764, but the tradition wasn´t common before 1920-30. In the old days when the julian calender was in use, the 13 december was the longest night.
