Halloween (or Hallowe’en) is a holiday celebrated on October 31, thought to be one of the night of the year when ghosts, witches and fairies are especially active.
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.
The carved pumpkin lit by a candle inside is one of Halloween's most prominent symbols in America and is commonly called a jack-o'-lantern. Originating in Europe, these lanterns were first carved from a turnip or rutabaga. Believing that the head was the most powerful part of the body, containing the spirit and the knowledge, the Celts used the "head" of the vegetable to frighten off any superstitions.
Halloween costumes are traditionally those of monsters such as ghosts, skeletons, witches, and devils. Costumes are also based on themes other than traditional horror, such as those of characters from television shows, movies, and other pop culture icons.
