It was going to have at least part of that regularity, exactly: probably slightly simplified rather than having a lot of the feast days etc (which would then mean I'd have to think about a year-tracking time system) to a system where on Sunday you were expected to attend there rather than work, and that this would also be a key moment for getting certain bits of information or advancing certain bits of the plot, because it's also the one location that all the NPCs also have to be at.
I am still hoping to get the time to do it at some point, anyhow! I've just had it confirmed that I'm defending the doctorate in late October so I'm hoping this will be a winter for getting creative stuff done.
