The National Day of Sweden (Swedish: Sveriges nationaldag [ˈsvæ̌rjɛs natɧʊˈnɑ̂ːldɑːɡ] ^ⓘ) is the national day of Sweden, observed annually as a public holiday on 6 June. Prior to 1983, the day was celebrated only as the Swedish Flag Day (Swedish: Svenska flaggans dag). It was officially named the Swedish National Day by the parliament of Sweden in 1983, and became a public holiday in 2005.^[1] The day is celebrated in honor of the election of Gustav Vasa as King of Sweden in 1523 and of the adoption of the constitutions of 1809 and 1974.
