Seven Sleepers Day, known as Siebenschläfertag, is observed in Germany every June 27. This feast day commemorates the Christian legend of the Seven Sleepers of Ephesus, a group of youths who were persecuted for their faith and fell asleep in a cave, awakening 180 years later when Christian persecution had ended. The day has historical roots as a commemoration established in the Middle Ages and is associated with weather lore, which suggests that the weather on this day predicts the average weather for the following seven weeks. Although there is some debate regarding the correct date due to calendar reforms, it remains celebrated on June 27. Notably, the day is distinct from the edible dormouse, which is also called Siebenschläfer in Germany.
