Examples
The following 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] );

	Remarks
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.
