The anniversary was approved by the Swedish Academy in 2010, and was held for the first time in 2011.

[1] 24 February was chosen as the date of the anniversary, as this was also the birthday of Carl Axel Gottlund, a collector of folk poetry and a defender of the status of the Finnish language.

[5] The anniversary is observed in various parts of Sweden, including Stockholm, Eskilstuna, Gothenburg, Västerås and Nykvarn.

For example, in 2017, more than a thousand people attended the celebration at Stockholm City Hall.

[7] In 2019, the seal was voted by the listeners of SR's Finnish-language channel Sveriges Radio Finska (formerly known as Sisuradio) as the symbolic national animal of the Sweden Finns.
