December 13th was also the Winter Solstice, the shortest day of the year, in the old 'Julian' Calendar and a pagan festival of lights in Sweden was turned into St. Lucia's Day.
St. Lucia's Day is now celebrated by a girl dressing in a white dress with a red sash round her waist and a crown of candles on her head. Small children use electric candles but from about 12 years old, real candles are used!
