Halloween is a holiday celebrated on the night of October 31. Common Halloween activities include trick-or-treating, ghost tours, bonfires, costume parties, visiting "haunted houses", carving Jack-o'-lanterns, reading scary stories and watching horror movies. Irish 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 Ireland (where it originated), the United States, Canada, Puerto Rico, the United Kingdom, New Zealand, and occasionally in parts of Australia.
