dd-mm-yyyy in Calendar with US settings
My MacBook Pro (13-inch, M1, 2020) running Monterey (12.6) is set to System Preferences/Language & Region to US (custom), I have changed the settings under System Preferences/Language & Region/Advanced to dd-mm-yyyy, the Calendar app continues to show it as mm-dd-yyyy, which I can't abide, since I live in Europe, plus it seems completely illogical to me anyway. I work in a second language AND in US English, so I need other settings on the computer to conform to US English, such as spelling. Is there a way to make the Calendar app conform to the settings in the customized System Preferences without changing the region?
