Father's Day in Denmark is observed every June 5 and celebrates fathers and father figures. This holiday was adopted from the American tradition, originally initiated by Sonora Smart Dodd to honor her father, Civil War veteran William Jackson Smart. While the original American date was June 5, many Scandinavian countries shifted the celebration to the second Sunday in November in the 1930s. However, Denmark retained the June 5 date due to a lack of communication from the government regarding the change. The celebration coincides with Constitution Day, another national public holiday in Denmark, making it a significant day for both occasions.
