DATEDIF(); an alternative available?
 

I wouldn't have a clue how to write a udf to replace this. In another
post, in this group, I was informed that this undocumented excel
function was broken in 2007 (in a service pak). Is an alternative
available?

Thank you.

You might be able to use this function I wrote back in my compiled VB
days... it will should work in Excel as either a normal function to be
called by other VB code or as a UDF (User Defined Function) directly on the
worksheet...

Function YMD(StartDate As Date, EndDate As Date) As String
Dim TempDate As Date
Dim NumOfYears As Long
Dim NumOfMonths As Long
Dim NumOfWeeks As Long
Dim NumOfDays As Long
Dim NumOfHMS As Double
Dim TSerial1 As Double
Dim TSerial2 As Double
NumOfYears = DateDiff("yyyy", StartDate, EndDate)
TSerial1 = TimeSerial(Hour(StartDate), _
Minute(StartDate), Second(StartDate))
TSerial2 = TimeSerial(Hour(EndDate), _
Minute(EndDate), Second(EndDate))
NumOfHMS = 24 * (TSerial2 - TSerial1)
If NumOfHMS < 0 Then
NumOfHMS = NumOfHMS + 24
EndDate = DateAdd("d", -1, EndDate)
End If
StartDate = DateSerial(Year(EndDate), _
Month(StartDate), Day(StartDate))
If StartDate EndDate Then
StartDate = DateAdd("yyyy", -1, StartDate)
NumOfYears = NumOfYears - 1
End If
NumOfMonths = DateDiff("m", StartDate, EndDate)
StartDate = DateSerial(Year(EndDate), _
Month(EndDate), Day(StartDate))
If StartDate EndDate Then
StartDate = DateAdd("m", -1, StartDate)
NumOfMonths = NumOfMonths - 1
End If
NumOfDays = Abs(DateDiff("d", StartDate, EndDate))
YMD = CStr(NumOfYears) & " year" & _
IIf(NumOfYears = 1, "", "s")
YMD = YMD & ", "
YMD = YMD & CStr(NumOfMonths) & " month" & _
IIf(NumOfMonths = 1, "", "s")
YMD = YMD & ", "
YMD = YMD & CStr(NumOfDays) & " day" & _
IIf(NumOfDays = 1, "", "s")
End Function

I will give it a shot. Thank you very much.

Rick,

It seems to me this is a mess of Microsoft making, the function should have
been removed from E2007 or supported. The only error I was aware of is where
it can return -1 days if doing (say) as DOB calculation using years, months
and days, This latest bug is new to me and as a result I'll stop using or
recommending it. Thanks for the tip.

Mike
