So if you haven't visited a cemetery yet today, it's not too late. If you didn't go to Mass this morning, you can still gain this indulgence between All saints day and the octave, every day in fact. So take advantage of these days to pray for your loved ones who have gone before you in the sign of faith. And may God give us all the grace of final perseverance.
Correction: A partial indulgence is gained for visiting a cemetery and devoutly praying for the dead. To gain a plenary indulgence it's necessary to visit a cemetery each day within the octave of All Saints. If you are like me and consider cemeteries holy ground, it is an easy daily work to perform.
