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.
