Saint Lucia's Day, also known as Lucy for short, is observed on December 13, 2017 and is the Church feast day dedicated to Saint Lucy. Its modern day celebration is generally associated with Sweden and Norway but is also observed in Europe countries. In the United States it is celebrated with cookies on the mantel in states for a large number of people of Scandinavian ancestry, often centered around church events.
In traditional celebrations, Saint Lucy comes as a young woman with lights and sweets. Wearing a white gown with a red sash and a crown of candles on her head, she walks at the head of a procession of women, each holding a candle. The candles symbolize the fire that refused to take St. Lucia's life when she was sentenced to be burned. The women sing a Lucia song while entering the room, to the melody of the traditional Neapolitan song Santa Lucia. After finishing this song, the procession sings Christmas carols or more songs about Lucia. (With material from: Wikipedia)
