St. Catherine's Day, also known as Kadripäev, is celebrated in Estonia on November 25th. It marks the arrival of winter and the end of harvest season. Historically, it commemorated the martyrdom of St. Catherine and was associated with keeping herds of livestock. Traditional customs involved people dressing up and singing songs door-to-door in exchange for gifts of food and supplies. Men and women sometimes dressed as women. The songs focused on luck with herds rather than harvest. Today, St. Catherine's Day remains popular in Estonia, especially among students and rural communities.
