Halloween (a shortening of All Hallows’ Evening), also known as Hallowe'en or All Hallows' Eve,[4] is a yearly holiday observed around the world on October 31, the night before All Saints Day. Much like Day of the Dead celebrations, the Christian feast of All Hallows' Eve also incorporates traditions from pagan harvest festivals and festivals honoring the dead, particularly the Celtic Samhain.[4][5][6] Typical festive Halloween activities include trick-or-treating (also known as "guising"), attending costume parties, carving jack-o'-lanterns, lighting bonfires, apple bobbing, visiting haunted attractions, playing pranks, telling scary stories, watching horror films, as well as the the religious observances of praying and attending vigils or church services.[2][1][3]
