Excel - VBA - is day the last day of a calendar month?


Is there any easy way to find out if a date is the last day of a calendar month in VBA?

For example, 30 October 2012 is not a last day but 31 October 2012 is a last day

Many thanks in advance

If DateSerial(Year(MyDate), Month(MyDate) + 1, 0) = MyDate Then
        MsgBox "Date is the last day of the month."

You can find it by taking the current month and incrementing it by 1 then decrement the day by 1.  Here is a sample taken from Microsoft's MSDN site.

Function dhLastDayInMonth(Optional dtmDate As Date = 0) As Date
    ' Return the last day in the specified month.
    If dtmDate = 0 Then
        ' Did the caller pass in a date? If not, use
        ' the current date.
        dtmDate = Date
    End If
    dhLastDayInMonth = DateSerial(Year(dtmDate), _
     Month(dtmDate) + 1, 0)
End Function

If you want to know whether a date is the last of the month just check whether the next day is the 1st

something like

If Day(MyDate + 1) = 1 Then.....
