Localization with first day of week different from Sunday is broken

[flo-l]

Describe the bug
If a locale does specify a differen first day of the week than sunday, the calendar is showing wrong date/weekday combinations.

To Reproduce
Steps to reproduce the behavior:

1. use a locale that sets a different weekday than sunday as first day of the week, eg. en-GB.
2. look at the calendar and check if date and weekday match

Expected behavior
The grid of days should be shifted, such that eg. mondays are in the first column.

Hi, it's some progress in this issue?

I'm currently solving the localization for cs and I'm solving exactly this problem that the date doesn't match the day of the week

Thank you
