Things to do in November
Visit a Cemetery
An indulgence, applicable only to the Souls in Purgatory, is granted to the faithful, who devoutly visit a cemetery and pray, even if only mentally, for the departed.
The indulgence is plenary each day from the 1st to the 8th of November; on other days of the year it is partial.
Your blogger is pretty sure that a columbarium counts as a cemetery.
Recite the Requiem Aeternam
Eternal rest grant to them, O Lord, and let perpetual light shine upon them. May they rest in peace. (Roman Breviary)
partial indulgence, applicable only to the souls in purgatory.
And many others.
