Halloween is a festival of Scottish-Irish origin, held on All Hallow’s Eve, the night of October 31. Elements of the customs connected with Halloween can be traced to a Druid ceremony in pre-Christian times. The Celts had festivals for two major gods -- a sun god and a god of the dead, called Sanhaim, whose festival was held on November 1, the beginning of the Celtic New Year. The festival of the dead was gradually incorporated into Christian ritual. In the 9th century, a feast in honor of all the saints, “All Hallows”, was fixed on November 1, and in the 11th century, November 2 was specified as All Soul’s Day to honor the souls of the dead.
