CalendarAlgorithmType Enumeration

CalendarAlgorithmType Enumeration

Specifies whether a calendar is solar-based, lunar-based, or lunisolar-based.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)]
public enum CalendarAlgorithmType

Member nameDescription
LunarCalendarA lunar-based calendar.
LunisolarCalendarA lunisolar-based calendar.
SolarCalendarA solar-based calendar.
UnknownAn unknown calendar basis.

A date calculation for a particular calendar depends on whether the calendar is solar-based, lunar-based, or lunisolar-based. For example, the GregorianCalendar, JapaneseCalendar, and JulianCalendar classes are solar-based, the HijriCalendar and UmAlQuraCalendar classes are lunar-based,.and the HebrewCalendar and JapaneseLunisolarCalendar classes are lunisolar-based, thus using solar calculations for the year and lunar calculations for the month and day.

A CalendarAlgorithmType value, which is returned by a calendar member such as the Calendar.AlgorithmType property, specifies the foundation for a particular calendar.

The following code example demonstrates the AlgorithmType property and the CalendarAlgorithmType enumeration.

// This example demonstrates the Calendar.AlgorithmType property and 
// CalendarAlgorithmType enumeration. 

using System;
using System.Globalization;

class Sample 
{
    public static void Main() 
    {
    GregorianCalendar grCal = new GregorianCalendar();
    HijriCalendar     hiCal = new HijriCalendar();
    JapaneseLunisolarCalendar 
                      jaCal = new JapaneseLunisolarCalendar();
    Display(grCal);
    Display(hiCal);
    Display(jaCal);
    }

    static void Display(Calendar c)
    {
    string name = c.ToString().PadRight(50, '.');
    Console.WriteLine("{0} {1}", name, c.AlgorithmType);
    }
}
