Leap years in the Taiwan calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

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

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

using System;
using System.Globalization;


public class SamplesTaiwanCalendar  {

   public static void Main()  {

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

      // Checks all the months in five years in the current era. 
      int iMonthsInYear;
      for ( int y = 90; y <= 94; y++ )  {
         Console.Write( "{0}:\t", y );
         iMonthsInYear = myCal.GetMonthsInYear( y, TaiwanCalendar.CurrentEra );
         for ( int m = 1; m <= iMonthsInYear; m++ )
            Console.Write( "\t{0}", myCal.IsLeapMonth( y, m, TaiwanCalendar.CurrentEra ) );
         Console.WriteLine();
      }

   }

}
