An integral part of the ancient Persian festival Charshanbe Suri (Fireworks Wednesday) is a spoon-banging ritual, which seems to be an ancestor of the trick-or-treating in modern Halloween celebrations.Every year on the eve of the last Tuesday of the Iranian calendar year, Iranian people do some trick or treating, literally called spoon-banging, where youngsters in disguises visit neighbours and receive snacks.By the light of the bonfires they have lit, they run through the streets banging on pots and pans with spoons in a ceremony called
Qashoq-Zani to beat out the last unlucky Wednesday of the year, while they knock on doors to ask for treats. Indeed, Halloween is a Celtic variation of this night.
