Happy Halloween!

Halloween (or Hallowe'en) is an annual holiday observed on October 31, which commonly includes activities such as trick-or-treating, attending costume parties, carving jack-o'-lanterns, bonfires, apple bobbing, visiting haunted attractions, playing pranks, telling scary stories, and watching horror films.

Origin of name 

The word Halloween is first attested in the 16th century and represents a Scottish variant of the fuller All-Hallows-Even ("evening"), that is, the night before All Hallows Day.Although the phrase All Hallows is found in Old English (ealra hālgena mæssedæg, mass-day of all saints), All-Hallows-Even is itself not attested until 1556.

Trick-or-treating is a customary celebration for children on Halloween. Children go in costume from house to house, asking for treats such as candy or sometimes money, with the question, "Trick or treat?" The word "trick" refers to a (mostly idle) "threat" to perform mischief on the homeowners or their property if no treat is given. In some parts of Scotland children still go guising. In this custom the child performs some sort of trick, i.e. sings a song or tells a ghost story, to earn their treats.
