Åland's Autonomy Day

Åland's Autonomy Day, or Åland's Self-Government Day, is celebrated annually on 9 June to commemorate the first meeting of the Åland County Council on that date in 1922. Åland's self-government from Finland was established in 1921 by a decision of the League of Nations, following the Åland Movement's demand for reunification with Sweden.
Provisions on Åland's Autonomy Day are set out in Provincial Act on Åland's Autonomy Day. According to the Provincial Act on the Åland flag, the day is an official flag-flying day in the autonomous region. It is a paid holiday for employees in the regional and municipal public sectors.
The 100th anniversary of Åland’s autonomy was observed on 9 June 2021, followed by a year of celebrations.
