A common year has 354 days and a leap year has 355 days.

The following example lists the number of days in ten consecutive years and calls the IsLeapYear method to determine which years are leap years.


using System;
using System.Globalization;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      Calendar cal = new UmAlQuraCalendar();
      int currentYear = cal.GetYear(DateTime.Now);

      for (int year = currentYear; year <= currentYear + 9; year++)
         outputBlock.Text += String.Format("{0:d4}: {1} days {2}", year,
                           cal.GetDaysInYear(year, cal.Eras[UmAlQuraCalendar.CurrentEra]),
                           cal.IsLeapYear(year, cal.Eras[UmAlQuraCalendar.CurrentEra]) ?
                              "(Leap Year)" : "") + "\n";
   }
}
// The example displays the following output:
//       1431: 354 days
