HijriCalendar::IsLeapYear Method (Int32, Int32)

Determines whether the specified year in the specified era is a leap year.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual bool IsLeapYear(
	int year, 
	int era
) override

Parameters

year
Type: System::Int32
An integer that represents the year.
era
Type: System::Int32
An integer that represents the era.

Return Value

Type: System::Boolean
true if the specified year is a leap year; otherwise, false.

ExceptionCondition
ArgumentOutOfRangeException

era is outside the range supported by this calendar.

-or-

year is outside the range supported by this calendar.

In every 30-year cycle that ends with a year that is evenly divisible by 30, the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th, and 29th years are leap years. A common year has 354 days and a leap year has 355 days.

The following code example calls the IsLeapYear method for five years in each of the eras.


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

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

   // Displays the header.
   Console::Write( "YEAR\t" );
   for ( int y = 1421; y <= 1425; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();

   // Checks five years in the current era.
   Console::Write( "CurrentEra:" );
   for ( int y = 1421; y <= 1425; y++ )
      Console::Write( "\t {0}", myCal->IsLeapYear( y, HijriCalendar::CurrentEra ) );
   Console::WriteLine();

   // Checks five years in each of the eras.
   for ( int i = 0; i < myCal->Eras->Length; i++ )
   {
      Console::Write( "Era {0}:\t", myCal->Eras[ i ] );
      for ( int y = 1421; y <= 1425; y++ )
         Console::Write( "\t {0}", myCal->IsLeapYear( y, myCal->Eras[ i ] ) );
      Console::WriteLine();

   }
}

/*
This code produces the following output.

YEAR            1421    1422    1423    1424    1425
CurrentEra:     False   False   True    False   False
Era 1:          False   False   True    False   False
