Midsummer, also known as St John's Day, is the period of time centered upon the summer solstice, and more specifically the Northern European celebrations that accompany the actual solstice or take place on a day between June 21 and June 25 and the preceding evening. The exact dates vary between different cultures. Many celebrations still center around the day of the astronomical summer solstice. Some choose to hold the rite on June 21, even when this is not the longest day of the year, and some celebrate June 24, the day of the solstice in Roman times.
Midsummer is especially important in the cultures of Scandinavia, and the Baltics. In Sweden the Midsummer is such an important festivity that there have been serious discussions to make the Midsummer's Eve into the National Day of Sweden, instead of 6 June. It may also be referred to as St. Hans Day.
At HATM, I celebrate with a Summer Solstice bonfire!
