CalendarAlgorithmType Enumeration

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

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

'Declaration
<ComVisibleAttribute(True)> _
Public Enumeration CalendarAlgorithmType
'Usage
Dim instance As CalendarAlgorithmType

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

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.

Class Sample
   Public Shared Sub Main()
      Dim grCal As New GregorianCalendar()
      Dim hiCal As New HijriCalendar()
      Dim jaCal As New JapaneseLunisolarCalendar()
      Display(grCal)
      Display(hiCal)
      Display(jaCal)
   End Sub 'Main

   Shared Sub Display(c As Calendar)
      Dim name As String = c.ToString().PadRight(50, "."c)
      Console.WriteLine("{0} {1}", name, c.AlgorithmType)
   End Sub 'Display
End Class 'Sample

'This code example produces the following results: 

'System.Globalization.GregorianCalendar............ SolarCalendar 
'System.Globalization.HijriCalendar................ LunarCalendar 
'System.Globalization.JapaneseLunisolarCalendar.... LunisolarCalendar
