The Day of the Finnish Identity is observed in Finland every May 12, commemorating the birthday of Johan Vilhelm Snellman, an influential philosopher and statesman born in 1806. This day celebrates Snellman's significant contributions to Finnish culture, particularly his advocacy for the Finnish language during the mid-19th century. Although it is not an official flag day, it is customary to fly the Finnish flag from 8 a.m. to sunset. Snellman played a crucial role in Finnish history, serving as a member of the Senate and Chancellor of the Exchequer, where he facilitated important reforms, including a language decree from the Russian Emperor and the introduction of the Finnish markka as the national currency. The day serves as a cultural observance, highlighting the importance of Finnish identity and heritage.
