Remarks

The Korean calendar is exactly like the Gregorian calendar, except that the year and era are different.

The KoreanCalendar class recognizes only the current era.

Leap years in the Korean calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

The Korean calendar has 12 months with 28 to 31 days each:

February has 29 days during leap years and 28 days during common years.

The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the first day of January in the year 4334 of the current era in the Korean calendar.

Each CultureInfo object supports a set of calendars. The CultureInfo.Calendar property returns the default calendar for the culture, and the CultureInfo.OptionalCalendars property returns an array containing all the calendars supported by the culture. To change the calendar used by a CultureInfo object, the application can set the DateTimeFormatInfo.Calendar property of CultureInfo.DateTimeFormat to a new Calendar object if the new calendar is one of the culture's optional calendars. The following example shows how to change the calendar for the ko-KR culture to the Korean calendar.

' Change the calendar used by a ko-KR CultureInfo object from Gregorian to Korean. 
Dim koreanCulture As New CultureInfo("ko-KR")
Dim originalCalendar As Calendar = koreanCulture.Calendar
Dim message As String = Nothing

' Confirm that the default calendar is not the Korean calendar.
If originalCalendar.ToString <> "System.Globalization.KoreanCalendar" Then
   ' Check whether the culture supports the Korean calendar.
   Dim supported As Boolean = False
   For Each supportedCal As Calendar In koreanCulture.OptionalCalendars
      If supportedCal.ToString = "System.Globalization.KoreanCalendar" Then
         supported = True            
         koreanCulture.DateTimeFormat.Calendar = supportedCal
         message = String.Format("Changed the current calendar for the {0} culture from {1} to {2}.", _
                                 koreanCulture.ToString(), _
                                 originalCalendar.ToString.Replace("System.Globalization.", ""), _
                                 supportedCal.ToString.Replace("System.Globalization.", ""))                                 
         Exit For
      End If
      If Not supported Then message = "The Korean calendar is not supported."
   Next        
Else
   message = String.Format("Korean is the default calendar for the {0} culture.", _
                           koreanCulture.ToString())
