test for leap year

Public Function IsLeapYear(Yr As Integer) As Boolean

'Set default return value
IsLeapYear = False
      
'If year is divisible with four then it's a leap year, unless
'is divisible by 100 but not by 400...
If Yr Mod 4 = 0 Then

      IsLeapYear = True

      If Yr Mod 100 = 0 Then

            If (Yr Mod 400) Then IsLeapYear = False

      End If

End If

End Function
