**Your software**  
My Mautic version is:6.0.2  
My PHP version is:8.3  
My Database type and version is:MariaDB11.4.7

**Your problem**  
My problem is:  
I can’t find how to change the date and calendar display format. It’s shown in the American format, starting with Sunday. Changing any regional settings doesn’t affect the calendar display.

I installed different languages for testing (I tried German, French, and British English) in Mautic, as well as localization settings in the operating system and PHP. Nowhere is the American format set. However, this doesn’t change how dates and the calendar are displayed.

How can the calendar format be changed? In my opinion, this setting should be clearly available in the configuration interface.
