Where do you start? Many stem from ancient folklore and are specific to certain areas, usually reflecting the desire among people to get out and about on the first holiday of spring and the end of a fasting period. That's why we get Easter Parades, Easter Bonnets, egg-rolling festivals, etc.

But surely the oddest custom used to take place in the Czech Republic, Hungary and Slovakia, where there was a tradition of spanking or whipping of woman on Easter Monday. In the morning, males throw water at females and spank them with a special handmade whip, consisting of eight, 12 or even 24 withies (willow rods), which is usually from half a metre to two metres long and decorated with coloured ribbons at the end. The spanking is symbolic and normally not painful or intended to cause suffering. A legend says females should be spanked in order to keep their health and beauty during the next year.
