JapaneseCalendar.MinSupportedDateTime Property

Gets the earliest date and time supported by the JapaneseCalendar class.

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

[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.

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.

The following code example gets the minimum value and the maximum value of the calendar.


using System;
using System.Globalization;


public class Example
{

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {

      // Create an instance of the calendar.
      JapaneseCalendar myCal = new JapaneseCalendar();
      outputBlock.Text += myCal.ToString() + "\n";

      // Create an instance of the GregorianCalendar.
      GregorianCalendar myGre = new GregorianCalendar();

      // Display the MinSupportedDateTime and its equivalent in the GregorianCalendar.
      DateTime myMin = myCal.MinSupportedDateTime;
      outputBlock.Text += String.Format("MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal.GetMonth(myMin), myCal.GetDayOfMonth(myMin), myCal.GetYear(myMin));
      outputBlock.Text += String.Format(" (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre.GetMonth(myMin), myGre.GetDayOfMonth(myMin), myGre.GetYear(myMin)) + "\n";

      // Display the MaxSupportedDateTime and its equivalent in the GregorianCalendar.
      DateTime myMax = myCal.MaxSupportedDateTime;
      outputBlock.Text += String.Format("MaxSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal.GetMonth(myMax), myCal.GetDayOfMonth(myMax), myCal.GetYear(myMax));
      outputBlock.Text += String.Format(" (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre.GetMonth(myMax), myGre.GetDayOfMonth(myMax), myGre.GetYear(myMax)) + "\n";

   }

}
