Today is National Sleepyhead Day (”unikeonpäivä”) in Finland. The holiday itse

Today is National Sleepyhead Day (”unikeonpäivä”) in Finland. The holiday itself has its roots in religion (originating from the legend of the Seven Sleepers of Ephesus), but nowadays it is a rather informal celebration. Traditionally, on this day, “sleepyheads” (people sleeping the longest) were woken up by using water, either by being thrown into the sea or a lake or by having water poured on them. The city of Naantali still observes this tradition as part of their grand sleepyhead festivities.
