[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Determines whether the specified month in the specified year in the specified era is a leap month.

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

Syntax

Public Overrides Function IsLeapMonth ( _
    year As Integer, _
    month As Integer, _
    era As Integer _
) As Boolean
public override bool IsLeapMonth(
    int year,
    int month,
    int era
)

Parameters

Return Value

Type: System..::.Boolean
This method always returns false, unless overridden by a derived class.

Exceptions

Exception Condition
ArgumentOutOfRangeException

year is outside the range supported by the calendar.

-or-

month is outside the range supported by the calendar.

-or-

era is outside the range supported by the calendar.

Remarks

Leap years in the Thai Buddhist 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 Thai Buddhist 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 ThaiBuddhistCalendar.
      Dim myCal As New ThaiBuddhistCalendar()

      ' Checks all the months in five years in the current era.
      Dim iMonthsInYear As Integer
      For y As Integer = 2544 To 2548
         outputBlock.Text += String.Format("{0}:" + ControlChars.Tab, y)
         iMonthsInYear = myCal.GetMonthsInYear(y, ThaiBuddhistCalendar.CurrentEra)
         For m As Integer = 1 To iMonthsInYear
            outputBlock.Text += String.Format(ControlChars.Tab + "{0}", myCal.IsLeapMonth(y, m, ThaiBuddhistCalendar.CurrentEra))
         Next 
         outputBlock.Text &= vbCrLf
      Next 
   End Sub  
End Class
