Midsummer is a celebration of the season of summer usually held at a date around the summer solstice. It has pagan pre-Christian roots in Europe.^[7][8][9]

The undivided Christian Church designated June 24 as the feast day of the early Christian martyr St John the Baptist, and the observance of St John's Day begins the evening before, known as Saint John's Eve. These are commemorated by many Christian denominations, such as the Roman Catholic Church, Lutheran Churches, and Anglican Communion,^[2][10] as well as by freemasonry.^[11] In Sweden, the Midsummer is such an important festivity that there have been proposals to make the Midsummer's Eve the National Day of Sweden, instead of June 6. In Finland, Estonia, Latvia and Lithuania, Midsummer's festival is a public holiday. In Denmark and Norway, it may also be referred to as St. Hans Day.^[12]
