Console::WriteLine( " DayOfMonth: {0}", myCal->GetDayOfMonth( myDT ) );
Console::WriteLine( " DayOfWeek: {0}", myCal->GetDayOfWeek( myDT ) );
Console::WriteLine();
}
int main()
{
// Sets a DateTime to April 3, 2002 of the Gregorian calendar.

Remarques
Le jour de l’année est défini comme le nombre de jours à partir du premier jour de l’année. Par exemple, GetDayOfYear pour le premier jour du premier mois retourne 1, et GetDayOfYear pour le dernier jour du dernier mois retourne le nombre total de jours dans cette année, qui est la même valeur retournée par GetDaysInYear.
