Midsummer, known as Juhannus in Finnish, is celebrated in Finland at the height of summer in June. It is a national holiday where Finns spend time in summer cottages or by lakes with friends, lighting bonfires, barbecuing, fishing, and boating. Traditional activities include spells for fertility and finding a spouse. Open-air dancing is also popular, with the culture of dance pavilions providing community and romance after the hardship of war.
