HijriCalendar.MinSupportedDateTime Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets the earliest date and time supported by this calendar.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.DateTimeThe earliest date and time supported by the HijriCalendar type, which is equivalent to the first moment of July 18, 622 C.E. in the Gregorian calendar.
Microsoft Visual Basic represents time of day as the specified time on the minimum date supported by the DateTime type, which is January 1, 0001 C.E. However, the HijriCalendar type does not support that minimum date. Consequently, if you call a method to format the time of day using the current calendar but you do not specify a format specifier, formatting uses the ISO 8601 sortable ("s") date/time pattern format specifier instead of the default general ("G") date/time pattern format specifier.
The following example gets the minimum value and the maximum value of the HijriCalendar class.
