No. Not in this context.
Sometimes feastday means a day when we feast, sometimes it can be used to mean an important day in the calendar. I think (actually I’m sure) that in this context the instruction is not trying to make the distinction of a feasting day versus a non-feasting day. It’s about an important day that takes precedence over the usual weekday cycle.
The important point of the instruction is that legitimate pastoral concerns can be a legitimate motivation for the local bishop to derogate from the universal norms of the calendar–again, in this context. More practically speaking, if the local bishop says to have All Saints Day on Friday evening and All Souls Day on Saturday evening this year, we should all understand that the Holy See has already spoken on this issue and addressed it 40 years ago. The bishop can promulgate the diocesan calendar to make this happen.
Anyway, I just realized I’m posting in the wrong thread. There are so many threads about this weekend’s liturgical calendar that I can’t keep them all straight.
Back to the original question: No, there is definitely no Gloria on All Souls Day because it’s a Mass for the Dead. It’s not a rubric on the All Souls page as I thought it might be; however the Gloria is never done in Masses for the Dead.
