Halloween is the night people dress up in costumes and partake of different activities that have a dark history attached to them. Most of them are based on pagan and ancient traditions from a time when people saw the world differently.

Hallow means saints that refer to All Saint's Day, which is November 1. Een is a shortening of the eve of the night before Nov 1. Halloween is an old term for the night before All Saints Day.

 All Hallows' Eve dates back to pre-Christian and pagan rituals.

All Hallows' Eve is based on Samhain, a festival rooted in Celtic origins at the summer's end in Ireland, Scotland, and the Isle of Man. On this night the Celt belief the dead can return and interact with the living. There would be offering of food for dead souls on this night. All hallow tide included All Saints' Eve, All Saints' Day, All Souls' Day celebrated in Spring by early Christianity.
