public class TaiwanLunisolarCalendar : EastAsianLunisolarCalendar


The Taiwan lunisolar calendar works exactly like the Gregorian calendar, except that the year and era are different. The System.Globalization.TaiwanLunisolarCalendar class calculates years using the Gregorian calendar, days and months using the System.Globalization.EastAsianLunisolarCalendar class, and recognizes only the current era.


For information about using the System.Globalization.TaiwanLunisolarCalendar class and the other calendar classes in the .NET Framework, see Working with Calendars.

The System.Globalization.TaiwanLunisolarCalendar class is derived from the System.Globalization.EastAsianLunisolarCalendar class, which represents the lunisolar calendar. The System.Globalization.EastAsianLunisolarCalendar class supports the sexagenary year cycle (which repeats every 60 years) in addition to solar years and lunar months. Each solar year in the calendar is associated with a Sexagenary Year, a Celestial Stem, and a Terrestrial Branch, and these calendars can have leap months after any month of the year.

A leap month can occur after any month in a year. For example, the EastAsianLunisolarCalendar.GetMonth(DateTime) method returns a number between 1 and 13 that indicates the month associated with a specified date. If there is a leap month between the eighth and ninth months of the year, the EastAsianLunisolarCalendar.GetMonth(DateTime) method returns 8 for the eighth month, 9 for the leap eighth month, and 10 for the ninth month.

Currently, the System.Globalization.TaiwanLunisolarCalendar is not used by any of the cultures supported by the System.Globalization.CultureInfo class. Therefore, this class can be used only to calculate dates in the Taiwan lunisolar calendar.

Each System.Globalization.CultureInfo object supports a set of calendars. The CultureInfo.Calendar property returns the default calendar for the culture, and the CultureInfo.OptionalCalendars property returns an array containing all the calendars supported by the culture. To change the calendar used by a System.Globalization.CultureInfo, the application should set the DateTimeFormatInfo.Calendar property of CultureInfo.DateTimeFormat to a new System.Globalization.Calendar.
