Finnish Swedish Heritage Day is celebrated on November 06, 2019. Finnish Swedish Heritage Day (Swedish: Svenska dagen, Finnish: Ruotsalaisuuden päivä) is a general flag day, which is celebrated in Finland on November 6. The day celebrates the Finland Swedish culture, and the bilinguality of Finland.
The main celebrations are aired in the radio, and many smaller celebrations are held around Finland in schools. Usually, the song Modersmålets sång is sung, celebrating the mother tongue. The Finnish Swedish Heritage Day is celebrated on the same day as Gustav Adolfsdagen in Sweden, the day that king Gustavus Adolphus of Sweden was killed at the Battle of Lützen in 1632.
The Finland Swedish Heritage Day was created in 1908, when the newly founded Swedish People's Party of Finland decided to celebrate a day for the Swedes. The intention was to strengthen the Swedish-speaking Finnish community. The reason why the day of the death of king Gustavus Adolphus was chosen was because this also was the time when the empire of Sweden was founded. (With material from: Wikipedia)
