On what night is Halloween observed when Oct. 31 falls on a Sunday?

Halloween isn't an established holiday by law. It is traditional that Halloween is Oct. 31 no matter what day of the week it falls on. Halloween dates from 837 when Pope Gregory IV instituted All Saints or All Hallows Day on Nov. 1 to take the place of an earlier festival known as the Peace of the Martyrs. The day was set aside to honor all saints, known and unknown. Halloween then is a shortened form of All Hallows Eve - the evening before All Hallows Day. Certainly, you have a choice of celebrating it on Oct. 30, Saturday, if you wish. Many of the area parties will be held then rather than on Sunday. It's probably appropriate to say some people equate Halloween with the occult or Satanism and don't approve of it at all.
