Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the earliest date and time supported by the JapaneseCalendar class.
Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
<ComVisibleAttribute(False)> _
Public Overrides ReadOnly Property MinSupportedDateTime As DateTime
[ComVisibleAttribute(false)]
public override DateTime MinSupportedDateTime { get; }
Property Value
Type: System.DateTime
The earliest date and time supported by the JapaneseCalendar type, which is equivalent to the first moment of January 1, 1868 C.E. in the Gregorian calendar.
Remarks
The start of the Meiji era is January 1, 1868 C.E., which in principle is the earliest date supported by the JapaneseCalendar class. However, to maintain compatibility with earlier versions of the .NET Framework, the JapaneseCalendar class permits an additional range of dates from January 1, 1868 through September 7, 1868 C.E.
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 JapaneseCalendar type does not support that minimum date. Consequently, if your application calls a method to format the time of day using the current calendar but does 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. For more information, see Standard Date and Time Format Strings.
Examples
The following code example gets the minimum value and the maximum value of the calendar.
