Saint Lucia's Day (sometimes Lucy for short) is the Church feast day dedicated to Saint Lucy and is observed on the 13th of December. Its modern day celebration is generally associated with Sweden and Norway but is also observed in Denmark, Estonia, Italy, Latvia, Finland, Hungary, Malta, Bosnia, Bavaria, Croatia, Slovakia, Spain and St. Lucia, West Indies. 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.Thanks, GF Newland, for alerting me to this!
In traditional celebrations, Saint Lucy comes as a young woman with lights and sweets. It is one of the few saint days observed in Scandinavia. In some forms, a procession is headed by one girl wearing a crown of candles (or lights), while others in the procession hold only a single candle each.
