St John's Day and the second day of the Midsummer celebrations (although this is not the astronomical summer solstice, see June 20) (Roman Catholic Church, Europe), and its related observances: Enyovden (Bulgaria)

Midsummer or Midsommar is a celebration of the season of summer, taking place on or near the date of the summer solstice in the Northern Hemisphere, the longest day of the year. The name midsummer mainly refers to summer solstice festivals of European origin. These cultures traditionally regard it as the middle of summer, with the season beginning on May Day. Although the summer solstice falls on 20, 21 or 22 June in the Northern Hemisphere, it was traditionally reckoned to fall on 23–24 June in much of Europe. These dates were Christianized as Saint John's Eve and Saint John's Day. It is usually celebrated with outdoor gatherings that include bonfires, maypole dancing and feasting.
