I also fear we may have blind spots, but maybe not from lack of searching. Maybe it's the octembre effect? This particular lemma stands out so much and is incredibly easy to google/search, so we do find a lot of results in the regions that use "octembre" more often.

I'm pretty sure its not an octembre effect, as the vast majority of entries weren't found based on octembre. Almost all entries so far have been from: 

Gallica searches for "calendrier", "calendar", "livre d'heures", and "horae". 
The JONAS variable "You are not allowed to view links. Register or Login to view.".

Neither of which should favour or not favour a specific variant of octobre. However, they do favour manuscripts and works designated or partly designated as french. They also tend exclude manuscripts that themselves are predominantly Latin but may contain notes or marginalia in the vernacular (especially the JONAS variable). Perhaps these potential SW France entries are not designated as either "french" or "oil-francais" and as such have been overlooked so far. 

When I asked google AI (pinch of salt) why I may not have found many occitan manuscripts from that area, it did mention that due to multiple reasons official works in the SW were pushed to be done in Latin, instead of local vernacular. Latin manuscripts and specific Occitan searches might be promising search avenues.
