In Switzerland, the day after New Year’s Day is known as Berchtoldstag and is celebrated primarily by children. Groups of playmates organize parties that feature nut eating and nut games followed by singing and folk dancing. A popular game is the building of “hocks” composed of four nuts placed close together with a fifth balanced on top. The children begin gathering and stockpiling nuts for Berchtold’s Day festivities early in the fall.
