Halloween or Hallowe'en (/ˌhæləˈwn, -ˈn, ˌhɑːl-/; a contraction of "All Hallows' Evening"), also known as Allhalloween, All Hallows' Eve, or All Saints' 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. It initiates the triduum of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed believers. Within Allhallowtide, the traditional focus of All Hallows' Eve revolves around the theme of using "humor and ridicule to confront the power of death."
