Most commonly known as Halloween or Hallowe'en (a contraction of All Hallows' Evening), the spooky festival is also referred to as Allhalloween, All Hallows' Eve, or All Saints' Eve. It is the eve of the Western Christian feast of All Hallows' Day, – also known as All Saints' Day. Supermarket shelves will soon be buckling under the weight of pumpkins with wardrobes clogged by fancy dress outfits, and there can only be one reason: Halloween, the spooky celebration observed every year on October 31, is nearly here.
