After Noon on All Saints Day, and until Midnight the following day, a person who has been to confession and Communion can gain a plenary indulgence, under the usual conditions, for the poor souls in Purgatory (who will be commemorated tomorrow) each time he visits a church or public oratory and recites the Our Father, the Hail Mary and the Glory be to the Father six times. This is a special exception to the ordinary law of the Church according to which a plenary indulgence for the same work can be gained only once a day. Some of the grave-visiting customs described on the entry for All Souls Day, then, may begin today in some places.
All Souls - [For the faithful departed]
§ 1. A plenary indulgence, applied exclusively to the souls in Purgatory, is granted to the Christian faithful who:
1° on each single day, from the first to the eighth day in November, devoutly visit a cemetery and, even if only mentally, pray for the faithful departed; [Note: one plenary indulgence for each day, if the usual conditions are met]
2° on the day of Commemoration of All Faithful Departed [November 2] (or, according to the Ordinary, on the preceding or subsequent Sunday, or on the day of the solemnity of All Saints) piously visit a church or oratory and there recite the Pater and the Credo.
