Finland’s official flag day observed on the Saturday between June 20 and 26 is Midsummer Day.
Finnish Midsummer Day is both a major national celebration and an official Finnish flag-flying day. The date is tied to the Saturday between June 20 and June 26, while Midsummer Eve occurs the previous evening. Flags are commonly flown from the evening before through the evening of Midsummer Day, following Finland’s special practice for this celebration.
The holiday is called Juhannus in Finnish and is associated with lakeside cottages, saunas, rural travel, music, and large bonfires known as kokko. Many Finns spend the holiday outside cities, reflecting the country’s strong connection with forests and lakes.
Finland has several official flag days, but Midsummer Day is especially distinctive because it is the country’s celebrated summer holiday and includes an extended flag-flying period. It is separate from Finland’s Independence Day on December 6.
