Hi,

can anybody helps me, how to set Monday in StartOfWeek atribute of modern DatePicker?

I try set it, but I think it does't work.

DatePicker3:
    Control: ModernDatePicker@1.0.0
    Properties:
      DefaultDate: =DataTable_aktivity_2.Selected.Datum
      Format: =DatePickerFormat.Short
      IsEditable: =true
      LayoutMinHeight: =16
      LayoutMinWidth: =16
      StartOfWeek: =StartOfWeek.Monday
      Width: =150

I use enumerate value:- DatePicker3:
    Control: ModernDatePicker@1.0.0
    Properties:
      DefaultDate: =DataTable_aktivity_2.Selected.Datum
      Format: =DatePickerFormat.Short
      IsEditable: =true
      LayoutMinHeight: =16
      LayoutMinWidth: =16
      StartOfWeek: =2
      Width: =150
“But the DatePicker still shows Sunday as the first day of the week. Am I doing something wrong, or is this a bug in the modern DatePicker?”
Can anybody give me advice?



Thanks Tom.

Hi @TomGaz,

The modern DatePicker control’s StartOfWeek property in Power Apps currently does not reliably change the first day of the week in the calendar popup. Setting StartOfWeek = StartOfWeek.Monday is the correct syntax, but due to known limitations or bugs in the control, it may still default to Sunday.

This is a known issue reported by users in the Power Apps community, where the calendar picker ignores the StartOfWeek setting and always starts on Sunday regardless of the property value.

You can try setting the app or screen’s Language property to a locale that uses Monday as the first day of the week (e.g., "en-GB") to influence the calendar behavior indirectly.

Note: The classic DatePicker control respects StartOfWeek better than the modern one, so consider using the classic control if this is critical.

I am sure some clues I tried to give. If these clues help to resolve the issue brought you by here, please don't forget to check the box Does this answer your question? At the same time, I am pretty sure you have liked the response!
