	int get();
	void set(int value);

Property Value

Type: System::Int32

An integer from -2 to 2 that represents the number of days to add or subtract from the calendar.

Exception Condition
ArgumentOutOfRangeException

The property is being set to an invalid value.

This implementation of the HijriCalendar class adjusts the calendar date by adding or subtracting a value from zero to two days to accommodate the variances in the start and the end of Ramadan and to accommodate the date difference between countries/regions. That value is stored in the HijriAdjustment property. If HijriAdjustment is not set explicitly, it derives its value from the settings in the regional and language options portion of Control Panel and is stored in the registry value HKEY_CURRENT_USER\Control Panel\International\AddHijriDate. However, that information can change during the life of the AppDomain. The HijriCalendar class does not detect changes in the system settings automatically.

The following code example shows how HijriAdjustment affects the date.

using namespace System;
using namespace System::Globalization;
int main()
{

   // Creates and initializes a HijriCalendar.
   HijriCalendar^ myCal = gcnew HijriCalendar;

   // Creates a DateTime and initializes it to the second day of the first month of the year 1422.
   DateTime myDT = DateTime(1422,1,2,myCal);

   // Displays the current values of the DateTime.
   Console::WriteLine( "HijriAdjustment is {0}.", myCal->HijriAdjustment );
   Console::WriteLine( "   Year is {0}.", myCal->GetYear( myDT ) );
   Console::WriteLine( "   Month is {0}.", myCal->GetMonth( myDT ) );
   Console::WriteLine( "   Day is {0}.", myCal->GetDayOfMonth( myDT ) );

   // Sets the HijriAdjustment property to 2.
   myCal->HijriAdjustment = 2;
   Console::WriteLine( "HijriAdjustment is {0}.", myCal->HijriAdjustment );
   Console::WriteLine( "   Year is {0}.", myCal->GetYear( myDT ) );
   Console::WriteLine( "   Month is {0}.", myCal->GetMonth( myDT ) );
   Console::WriteLine( "   Day is {0}.", myCal->GetDayOfMonth( myDT ) );

   // Sets the HijriAdjustment property to -2.
   myCal->HijriAdjustment = -2;
   Console::WriteLine( "HijriAdjustment is {0}.", myCal->HijriAdjustment );
   Console::WriteLine( "   Year is {0}.", myCal->GetYear( myDT ) );
   Console::WriteLine( "   Month is {0}.", myCal->GetMonth( myDT ) );
   Console::WriteLine( "   Day is {0}.", myCal->GetDayOfMonth( myDT ) );
}
