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.

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

using System;
using System.Globalization;


public class SamplesTaiwanCalendar  {

   public static void Main()  {

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

      // Displays the header.
      Console.Write( "YEAR\t" );
      for ( int y = 90; y <= 94; y++ )
         Console.Write( "\t{0}", y );
      Console.WriteLine();

      // Checks five years in the current era.
      Console.Write( "CurrentEra:" );
      for ( int y = 90; y <= 94; y++ )
         Console.Write( "\t{0}", myCal.IsLeapYear( y, TaiwanCalendar.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 = 90; y <= 94; y++ )
            Console.Write( "\t{0}", myCal.IsLeapYear( y, myCal.Eras[i] ) );
         Console.WriteLine();
      }

   }

}
