UmAlQuraCalendar.IsLeapDay Method (Int32, Int32, Int32, Int32)

Determines whether the specified date is a leap day.

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

public override bool IsLeapDay(
	int year,
	int month,
	int day,
	int era
)

Parameters

year
Type: System.Int32
A year.
month
Type: System.Int32
An integer from 1 through 12 that represents a month.
day
Type: System.Int32
An integer from 1 through 30 that represents a day.
era
Type: System.Int32
An era. Specify UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] or UmAlQuraEra.

Return Value

Type: System.Boolean
true if the specified day is a leap day; otherwise, false. The return value is always false because the UmAlQuraCalendar class does not support leap days.

ExceptionCondition
ArgumentOutOfRangeException

year, month, day, or era is outside the range supported by the UmAlQuraCalendar class.

A leap day is a day that occurs only in a leap year.

The following example calls the IsLeapDay method for the last day of the second month (February) for five years in each of the eras.


using System;
using System.Globalization;


public class SamplesHijriCalendar  {

   public static void Main()  {

      // Creates and initializes a HijriCalendar.
      HijriCalendar myCal = new HijriCalendar();

      // Creates a holder for the last day of the second month (February).
      int iLastDay;

      // 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++ )  {
         iLastDay = myCal.GetDaysInMonth( y, 2, HijriCalendar.CurrentEra );
         Console.Write( "\t{0}", myCal.IsLeapDay( y, 2, iLastDay, 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++ )  {
            iLastDay = myCal.GetDaysInMonth( y, 2, myCal.Eras[i] );
            Console.Write( "\t{0}", myCal.IsLeapDay( y, 2, iLastDay, myCal.Eras[i] ) );
         }
         Console.WriteLine();
      }

   }

}
