Halloween has been around since ancient times. It all started with an ancient Celtic festival of Samhain, a celebration in which people would light large bonfires and wear an array of costumes to scare off ghosts and evil spirits. This festival marked the end of harvest season and the beginning of winter or "The Darker Half" of the year. This celebration usually went on from the October 21 till November 1. There were many festivals held like this one around Scotland at the time, some being even older than the Celtic festival of Samhain itself.
