InGermany, June 27 is "Siebenschläfertag" (Seven Sleepers Day). If it rains that day, the rest of summer is supposedly going to be rainy. While it might seem to refer to the『Siebenschläfer』squirrel (Glis Glis), also known as the "edible dormouse", it actually commemorates the Seven Sleepers (the actual commemoration day is July 25).
