Halloween, also known as All Hallows' Eve, is a yearly celebration observed in a number of countries on 31 October, the eve of the Western Christian feast of All Hallows' Day. Halloween is a Christianized feast initially influenced by Celtic harvest festivals, with possible pagan roots, particularly the Gaelic Samhain. Typical festive Halloween activities include trick-or-treating, attending costume parties, decorating, carving pumpkins into jack-o'-lanterns, lighting bonfires, apple bobbing, visiting haunted attractions, playing pranks, telling scary stories, and watching horror films.
