In Finland, the Midsummer festival is known as Juhannus.
Juhannus is Finland’s celebration of Midsummer, held near the summer solstice. Its modern name comes from Johannes, the Finnish form of John, referring to John the Baptist; the festival’s older pre-Christian association was with Ukko, a Finnish sky and thunder deity.
Since 1955, Finnish Midsummer Day has been observed on a Saturday between June 20 and June 26, while the main festivities often begin on Friday evening. Bonfires, called kokko, are especially characteristic and are commonly lit beside lakes or along the coast.
Many Finns leave cities for cottages and spend the holiday with family and friends, often combining sauna, outdoor meals, music, and boating. The northern location also gives Juhannus its famous white-night atmosphere, with very little darkness around the solstice. Sweden and Norway have related celebrations, but their customary names differ.
