Make Datetimepicker independent from system date

Question

I am using windows 10 and Hijri calendar and I want my datetimepicker shows gregorian calendar instead of Hijri. Using WinForms .NET 4.8 I changed culturalInfo to "en-US" or InvariantCulture but still it wont change I tested these codes:

    Application.CulturalInfo=new CulturalInfo("en-US")
Application.CurrentUICulture=new CulturalInfo("en-US")
Thread.CuurentThread.CulturalInfo= new CulturalInfo("en-US")

CulturalInfo.DefaultThreadCurrentCulture =new CulturalInfo("en-US")

DateTimePicker / MonthCalendar don't care about the Thread. The calendar is taken from the System Locale — Jimi, Oct 26 '22 at 16:18
What about this? CulturalInfo.DefaultThreadCurrentUICulture =new CulturalInfo("en-US") — Mehdi Mowlavi, Feb 12 '23 at 10:59

Use this code.

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
