The Finnish Midsummer festival, celebrated around the June solstice, is called Juhannus.
Juhannus is named after Saint John the Baptist and is held on the Saturday between June 20 and 26. Many Finns leave cities for cottages beside lakes, where they enjoy saunas, swimming, boating, grilling, and time with family or friends. Bonfires, called kokko, are a prominent feature, especially in lakeside areas.
The festival combines Christian naming with older Finnish solstice customs. The white night is central to its atmosphere: in much of Finland, the sun remains above or close to the horizon for an exceptionally long time. Juhannus is also an official flag-flying day, and the Finnish flag is commonly displayed from the evening before through the following evening.
