Ireland, Canada, United Kingdom, United States and other nations celebrate Halloween on October 31.
The word Halloween or Hallowe’en dates to about 1745 and is of Christian origin, meaning “hallowed evening” or “holy evening.” It comes from a Scottish term for All Hallows’ Eve (the evening before All Hallows’ Day). In Scots, the word “eve” is “even,” and this is contracted to “e’en” or “een.” Over time, (All) Hallow(s) E(v)en shortened into Halloween.
It is one of those darker-themed celebrations, often conjuring up images of death and horror. As if in keeping with this theme, Josef Stalin’s body was removed from Lenin’s Tomb on October 31, 1961.
N.B. The carving of pumpkins into mock-horrific faces is an old tradition. This Jack‑o’-Lantern photo is taken from Dose of Funny.
