Saint Lucy's Day (Sankta Lucia, Saint Lucia) is the Church feast day dedicated to St. Lucy and is observed on December 13. It retains traditional forms of celebration mainly in Scandinavia, parts of the United States and southern Europe. It is celebrated in Sweden, Denmark, Estonia, Norway, Finland, Malta, Italy, Bosnia, Iceland, and Croatia. In the United States, people in areas of Minnesota and other states with Scandinavian roots continue to celebrate the holiday, often centered around church events. Before the reform of the Gregorian calendar in the 16th century, St. Lucy's Day fell close to the winter solstice on the Northern Hemisphere.
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.
