	int era
)

An integer from 1 to 12 that represents the month.
era
Type: System.Int32

ExceptionCondition
ArgumentOutOfRangeException

era is outside the range supported by this calendar.

-or-

year is outside the range supported by this calendar.

-or-

month 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.

A leap month is an entire month that occurs only in a leap year. The Hijri calendar does not have any leap months.

The following code example calls IsLeapMonth for all the months in five years in the current era.


using System;
using System.Globalization;


public class Example
{

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

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

      // Checks all the months in five years in the current era.
      int iMonthsInYear;
      for (int y = 1421; y <= 1425; y++)
      {
         outputBlock.Text += String.Format("{0}:\t", y);
         iMonthsInYear = myCal.GetMonthsInYear(y, HijriCalendar.CurrentEra);
         for (int m = 1; m <= iMonthsInYear; m++)
            outputBlock.Text += String.Format("\t{0}", myCal.IsLeapMonth(y, m, HijriCalendar.CurrentEra));
         outputBlock.Text += "\n";
      }

   }

}
