There are many indulgences, applicable only to the souls in Purgatory, that can be obtained during the month of November. From the fourth edition of the Enchiridion of Indulgences, 1999:
A plenary indulgence, applicable only to the souls in purgatory, is granted to the faithful who:
- On any and each day from November 1 to 8, devoutly visit a cemetery and pray, if only mentally, for the departed;
- On All Souls’ Day, devoutly visit a church or an oratory and recite an Our Father and the Creed.
A partial indulgence, applicable only to the souls in purgatory, is granted to the faithful who:
- Devoutly visit a cemetery and at least mentally pray for the dead;
- Devoutly recite Lauds or Vespers from the Office of the Dead or the prayer Requiem aeternam (i.e., Eternal rest grant unto them, O Lord, and let perpetual light shine upon them).
