What is Halloween?Well, Halloween or Hallowe'en (a contraction of All Hallows' Evening), also known as Allhalloween, All Hallows' Eve, or All Saints' Eve, is a spooky celebration observed every year in a number of countries on October 31 - the eve of the Western Christian feast of All Hallows' Day, also known as All Saints' Day. In 2017, Halloween falls on a Tuesday.
The Americanised (Americanized?) Halloween that we experience today actually originated in the Celtic fringes of Britain, and was adapted over the decades by Christian traditions, immigrants' conventions and an insatiable desire for sweets. http://hulumagazine.com
