Halloween is a holiday celebrated on October 31. Halloween activities include trick-or-treating, ghost tours, bonfires, costume parties, visiting haunted attractions, carving jack-o’-lanterns, reading scary stories, and watching horror movies.
Irish and Scottish immigrants carried versions of the tradition to North America in the nineteenth century. Other western countries embraced the holiday in the late twentieth century.
Halloween is celebrated in several countries of the Western world, most commonly in the United States, Canada, Ireland, Puerto Rico, Japan, the United Kingdom, and at times in parts of Australia and New Zealand.
