A few years ago Halloween fell on a Sunday. That year everyone moved Halloween from Sunday to Saturday. Since that year I think people may be confused on when to actually celebrate Halloween. This  year a lot of Halloween parties and dances occurred over the weekend and some families took their children trick-or-treating on Saturday. A couple of my co-workers had trick-or-treaters at their houses on Saturday. Both co-workers said they were not prepared for trick-or-treaters.
