Halloween (or Hallowe'en) is a holiday celebrated on the night of October 31. Traditional activities include trick-or-treating, ghost tours, bonfires, costume parties, visiting "haunted houses," and carving jack-o’-lanterns. The term is shortened from All-hallow-even, as it is the eve of All Hallows' Day, which is now also known as All Saints' Day. Irish and Scottish immigrants carried versions of the tradition to North America in the nineteenth century, and other Western countries embraced the holiday in the late twentieth century.
