Remarks
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.
A leap month is an entire month that occurs only in a leap year. The Korean calendar does not have any leap months.
Examples
The following code example calls the IsLeapMonth method for all the months in five years in the current era.
Imports System.Globalization
Public Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
' Creates and initializes a KoreanCalendar.
Dim myCal As New KoreanCalendar()
' Checks all the months in five years in the current era.
Dim iMonthsInYear As Integer
For y As Integer = 4334 To 4338
outputBlock.Text += String.Format("{0}:" + ControlChars.Tab, y)
iMonthsInYear = myCal.GetMonthsInYear(y, KoreanCalendar.CurrentEra)
For m As Integer = 1 To iMonthsInYear
outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapMonth(y, m, KoreanCalendar.CurrentEra))
Next
outputBlock.Text &= vbCrLf
Next
End Sub
End Class
