Many of the things you don't know about Easter have to do with odd, intensely national Holy Week traditions. So why not start off with the most unexpected one the Easter Witch. In Sweden and parts of Finland, a mini-Halloween takes place on either the Thursday or Saturday before Easter. Little girls dress up in rags and old clothes, too-big skirts and shawls and go door to door with a copper kettle looking for treats.
The tradition is said to come from the old belief that witches would fly to a German mountain the Thursday before Easter to cavort with Satan. On their way back, Swedes would light fires to scare them away, a practice honored today by the bonfires and fireworks across the land in the days leading up to Sunday.
