Select date dialogue starting on Monday

[Mauro Ghibaudo]

Would it be possible (or, if it already is and I missed it, where is the option) to have the selct date dialogue starting on Monday?

My system calendar already does, and I looked in Automate options, Date pick options and system options, but didn't find anything relevant.

The Calendar picker doesn't seem to support changing the first day of week, so it's using the default for the device locale/language, see:

A workaround may be to change the device language to English (UK), instead of English (US).

I'll consider using another "calendar" style picker.
