About Halloween
Halloween or Hallowe'en, also known as Allhalloween, All Hallows' Eve, or All Saints' Eve, is a celebration observed in a number of countries on October 31, the eve of the Western Christian feast of All Hallows' Day. It begins the three-day observance of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed.
Trick-or-treating is a Halloween custom for children in many countries. Children in costumes travel from house-to-house, asking for treats with the phrase "Trick or treat". The "treat" is usually some form of candy, although, in some cultures, money is used instead. The "trick" is a usually idle threat to perform mischief on the homeowners or their property if no treat is given. Trick-or-treating usually occurs on the evening of October 31. Some homeowners signal that they are willing to hand out treats by putting up Halloween decorations outside their doors; others simply leave treats available on their porches for the children to take freely.
