My Grandmother passed away last year in Sep 17, we offered Masses for her at the time. I’d like to offer one again on this coming Sep 17. Is that ok? Can I offer a Mass whenever I want for her? Or is there certain times in the year? My parents say that a Mass has to be offered a month before her memorial. Is this correct? It does not make any sense to me! My parents are not very religious so I don’t know if I should trust their word for it.
P.S. Pardon me if you find a word that does not make sense or a typo. This is not my language.
