It's been a few weeks since i last launched my KDE Neon VM, but earlier today i did. It was still on Plasma 5.7.5, but there were >300 updates waiting. After updating, it became Plasma 5.8.2. I was quite disappointed to note that, in its latest guise, this bug is not fixed.
As an Australian, in Oz [Australia], it's "sub-optimal" that i'll have to continue doing my discovered workaround per my https://bugs.kde.org/show_bug.cgi?id=370445 post, apparently even after we get 5.8.2 in Maui, unless the Maui Devs can manage to achieve what apparently the KDE Devs have not.
"Discovered Workaround:
i found that by retaining "Australia - Australian English (en_AU)" in the widget's "Set Time Format..." dialog's "Region" field, & manually setting it also in all individual fields below, EXCEPT "Time", then choosing somewhere DIFFERENT than Oz or NZ for "Time", the widget's calendar then correctly shows weeks beginning Mondays. Eg, if i instead use UK, or Norfolk Island, or Anguilla [etc (i did not try any others)], the widget's calendar then becomes correct. See my picture; the associated calendar is correct ONLY because "Time" field is NOT using Oz or NZ."
