Console::WriteLine( " DayOfWeek: {0}", myCal->GetDayOfWeek( myDT ) );
Console::WriteLine();
}
int main()
{
// Sets a DateTime to April 3, 2002 of the Gregorian calendar.
DateTime myDT = DateTime(2002,4,3,gcnew GregorianCalendar);
// Creates an instance of the TaiwanCalendar.

Remarks
The day of the year is defined as the number of days from the first day of the year. For example, GetDayOfYear for the first day of the first month returns 1, and GetDayOfYear for the last day of the last month returns the total number of days in that year. The total is the same as the value returned by GetDaysInYear.
