St. Nicholas Day is celebrated on December 6th in honor of Saint Nicholas, a 4th-century bishop known for his generosity and kindness. This day is particularly popular in many European countries, where children place their shoes or stockings by the door, hoping to find small gifts or treats left by St. Nicholas. Traditions vary by region; in some places, children sing songs or leave out carrots for St. Nicholas's horse. In countries like Germany and the Netherlands, festive parades and markets are common, celebrating the spirit of giving and the legacy of Saint Nicholas as a protector of children and the needy.
