This tip applies to Excel 2007 and 2010

When developing a worksheet, you may have a need to know the last business day of a given month. Assuming that your business days run Monday through Friday, the following formula will return the desired date:

```=DATE(YEAR(A1),MONTH(A1)+1,0)-(MAX(0,WEEKDAY
(DATE(YEAR(A1),MONTH(A1)+1,0),2)-5))
```

This formula returns a date that is only a Monday through Friday, and always the last such day in the month represented by the date in A1. For some purposes, you may need to know what the last Friday of any given month is. This is easily determined with this formula:

```=DATE(YEAR(A1),MONTH(A1)+1,0)-WEEKDAY(DATE
(YEAR(A1),MONTH(A1)+1,0))+(WEEKDAY(DATE
(YEAR(A1),MONTH(A1)+1,0))>5)*7-1
```

This formula calculates the last day of the month for the date in cell A1 and, based on what day of the week that date is, subtracts the appropriate number of days to return the previous Friday.

If you want to take business holidays into account, then the complexity of the formula gets quite high, quite quickly. Because of that, it is best to create a user-defined function (a macro) that will determine the last business day and compensate for holidays.

The following macro returns a date, Monday through Friday, that represents the last business day. The date is compared against a holiday list (HolidayList), which should be a named range in your workbook. If the date is found to be a holiday, then the ending business day is decremented until a suitable day is located.

```Function LastWorkDay(lRawDate As Long, _
Optional rHolidayList As Range, _
Optional bFriday As Boolean = False) As Long

LastWorkDay = DateSerial(Year(lRawDate), _
Month(lRawDate) + 1, 0) - 0
If bFriday Then
LastWorkDay = MakeItFriday(LastWorkDay)
Else
LastWorkDay = NoWeekends(LastWorkDay)
End If

If Not rHolidayList Is Nothing Then
Do Until myMatch(LastWorkDay, rHolidayList) = 0
LastWorkDay = LastWorkDay - 1
If bFriday Then
LastWorkDay = MakeItFriday(LastWorkDay)
Else
LastWorkDay = NoWeekends(LastWorkDay)
End If
Loop
End If
End Function
```
```Private Function myMatch(vValue, rng As Range) As Long
myMatch = 0
On Error Resume Next
myMatch = Application.WorksheetFunction _
.Match(vValue, rng, 0)
On Error GoTo 0
End Function
```
```Private Function NoWeekends(lLastDay As Long) As Long
NoWeekends = lLastDay
If Weekday(lLastDay) = vbSunday Then _
NoWeekends = NoWeekends - 2
If Weekday(lLastDay) = vbSaturday Then _
NoWeekends = NoWeekends - 1
End Function
```
```Private Function MakeItFriday(lLastDay As Long) As Long
MakeItFriday = lLastDay
While Weekday(MakeItFriday) <> vbFriday
MakeItFriday = MakeItFriday - 1
Wend
End Function
```

Notice that there are three private functions that are included. These functions are called from within the main LastWorkDay function. The first one, myMatch, is a "wrapper" for the regular Match method. This usage is included because of the required error handling.

The second function, NoWeekdends, is used to back a date up to the previous Friday if it just happens to be a Saturday or Sunday. The MakeItFriday function is used to ensure that a date will always be a Friday.

To use this user-defined function from your worksheet, you use it in a formula, like this:

```=LastWorkDay(A1, HolidayList, TRUE)
```

The first parameter (A1) is the date to be evaluated. The second parameter (HolidayList) is an optional list of holiday dates. As shown here, it is assumed that HolidayList is a named range in the worksheet. If this parameter is provided, then the function makes sure that any date it returns is not on the list of dates in HolidayList.

The final parameter is also optional; it can be either TRUE or FALSE. (The default, if it is not specified, is FALSE.) If this parameter is set to TRUE, then the function always returns the last Friday of the month. If this parameter is TRUE and the HolidayList is provided, then the function returns the last non-holiday Friday of the month.

I wanted the last workday of the current month, so this is what I came up with..

=workday(eomonth(today(),0),-1,0)

The last 0 can de replaced with a range of holidays to eliminate them as well.

It wasn't intended as a criticism; I just assumed by the way you asked the question that you weren't familiar with Excel.

However, now I see what you are talking about. I think the problem is actually with the line returns, not the spaces. You can save a step by double-clicking in the target cell (or pressing F2 to enter cell edit mode) and pasting the formula there. Before pressing enter, you can delete the extra line returns.

You are correct about the formatting on formula 2. If you don't want to use cell formatting you could also wrap the whole formula in the TEXT formula.

Thanks for the criticism Bryan and Martin. There are many people who come to me for advice on Excel, so my status is a bit different to what you've assumed.

Copying those two formulas and Pasting them does not work because they copy with spaces. I resolved this by pasting into Notepad, eliminating the spaces, then copying again and Pasting into Excel. The second formula actually gave a numerical result which had to be reformatted into a Date format.

I am so impressed with this tip and the comments. I spent hours learning from this. For Tony and others learning: The EOM...,0)part just gives the last day of the month. The second Workday and ,1 asks for the workday following that last day of the month. The first Workday and the ,-1, ask for the workday before. Basically, the double workday function simply eliminates the weekend dates.

Tony, have you used Excel before? These formulas might be a little advanced otherwise; there are tons of good, free, basic tutorials around the internet.

That being said, to use the first two formulas, all you have to do is type a date into cell A1, and then pick any other cell and copy/paste the formula into it. It will tell you the last working date of the month in cell A1.

To use the macro code, hit Alt+F11 to open the VBA IDE, then Insert > Module. Paste the code into the dialogue that opens, then use the last formula in the article to find the last working date.

How and where do I enter these formulas?

I'm completely lost.

SmeesterH,
very clever, I love that.

even simpler:
Workday(Workday(EOMonth(A1,0),1),-1)

2012-10-06 09:33:43

SmeestersH

Workday(Workday(Date(Y,M+1,0),1),-1)
