Nth Such-And-Such Day Of The Month

[Dave]

Function NthDay(NthDay As Long, DayOfWeek As Long, MonthNumber As Long, YearNumber As Long) As Date
  NthDay = DateSerial(YearNumber, MonthNumber, 1 + 7 * NthDay) - _
           Weekday(DateSerial(YearNumber, MonthNumber, 8 - DayOfWeek))
End Function

Can the UDF be extended to ensure that the answer relates to the criteria month. If a person asks for the 5th instance, the UDF should provide the answer only if the 5th is in the specified month otherwise "N/A"

Can the UDF's name and one of the criteria names be the same? I changed a word in "NthDay As Long" and "DateSerial(YearNumber, MonthNumber, 1 + 7 * NthDay) to "NthDayx"

I read the intro message but question and comment apply to the initial post.

Thanks Dave
