What I did:
In Preferences, I tried to change the first day of the week to Saturday.
The calendar continued to be what it was before (Friday or Sunday, etc.)
What I expected:
That the first day of the week in the popup calendar is Saturday.
Note that this does work for Friday and Sunday: changing the first day of the week changes the date pickers first day for Sunday or Friday.
Things that might be helpful to know (Agenda version, OS and model, etc):
- Agenda 14.1.1
- Mac Monterey, 12.4 Beta
