Again thank you for your accountability and attention.
Actually Hijri calendar and Persian Calendar are similar in structure but there are differences.
I realized that you don't support Persian calendar atm. But given the similarity of Hijri calendar and Persian Calendar can you please add Persian calendar in you component too?
As you know we can easily convert DateTime value to Persian DateTime value with using System.Globalization framework and PersianCalendar class Like this:
PersianCalendar pc=new PersianCalendar();
return pc.GetYear(value) + "/"+ pc.GetMonth(value).ToString("00") + "/" +pc.GetDayOfMonth(value).ToString("00");
And here is link of PersianCalendar class in Microsoft Document:
