The night before Halloween, October 30th, also goes by the moniker of "Devils Night." The Irish coined the term, with its origins going back to the 1880s. On Devil's Night, towns would experience mischief, blamed on goblins and fairies. When American culture adopted the tradition, it morphed into reckless youth toilet papering trees and soaping windows. Today, that event turned into the infamous "trick-or-treat" system kids enjoy around the world.
