Father's Day is observed in Sweden, Finland, Norway, Estonia, and Iceland on every second Sunday of November. The holiday originated in the USA, introduced in 1910 by Sonora Smart Dodd, and has since been adopted by various countries. In these five nations, the celebration includes mass events organized by schools and kindergartens, where children prepare concerts and festive activities for their fathers. Teachers conduct special lessons to highlight the importance of fathers in families. Additionally, many cities host merry events such as sports competitions and presentations showcasing men's professions, fostering a sense of community and celebration among fathers and their children.
