# Finding Fridays2

## Finding Fridays

(OP)
I'm looking for some VB code that will find the following Fridays from a given date in a cell.

> The first Friday following the given date

> The first Friday in the month of the given date

> The last Friday in the month of the given date

I have a fairly crude way to get the first but am having trouble with coding the others. Any suggestions will be gratefully considered.

### RE: Finding Fridays

Here's an attempt at the problem using functions in various cells.  Hope this helps!

A1 is the current date.

A12 is the first Friday after the current date:
=A1+6-WEEKDAY(A1,1)

A16 is the first day of the current month:
=EOMONTH(A1,-1)+1

D16 is the first Friday of the current month:
=A16+6-WEEKDAY(A16)

A20 is the last day of the current month:
=EOMONTH(A1,0)

D20 is the last Friday of the current month:
=IF(MONTH(A20-1-WEEKDAY(A20))=MONTH(A20+6-WEEKDAY(A20)),A20+6-WEEKDAY(A20),A20-1-WEEKDAY(A20))

Thank you BML and Flareman, both solutions work well and have solved the problem. While not VB I am more than happy with this solution and will incorporate it into my application.

### RE: Finding Fridays

There is a way to determine the day of the week with formulas.  Let's say A12 is the date.  Then just do a "mod(a12,7)".  This will return a value from 0 to 6.  With 0 being Sunday, and 6 being Saturday.

You could mod your current date.  Then have a cell that subtracts that value from 5.  Add this number back to your mod'd date, and you have the next Friday's date.

### RE: Finding Fridays

I'd love to be able to find Friday's faster and more frequently. They don't come often enough.

### RE: Finding Fridays

The following formulas seem to work in Excel 2000

Enter a date in cell A1

Next Friday
=IF(WEEKDAY(A1,2)<5,A1+(5-WEEKDAY(A1,2)),A1+(12-WEEKDAY(A1,2)))

Last Friday of month
=IF(WEEKDAY(EOMONTH(A1,0),2)=5,EOMONTH(A1,0),IF(WEEKDAY(EOMONTH(A1,0),2)<5,EOMONTH(A1,0)-(WEEKDAY(EOMONTH(A1,0),2)+2),IF(WEEKDAY(EOMONTH(A1,0),2)>5,EOMONTH(A1,0)-(WEEKDAY(EOMONTH(A1,0),2)-5))))

First Friday of month
=IF(WEEKDAY(EOMONTH(A1,-1),2)=5,EOMONTH(A1,-1)+7,IF(WEEKDAY(EOMONTH(A1,-1),2)<5,EOMONTH(A1,-1)+5-(WEEKDAY(EOMONTH(A1,-1),2)),IF(WEEKDAY(EOMONTH(A1,-1),2)>5,EOMONTH(A1,-1)+(12-WEEKDAY(EOMONTH(A1,-1),2)))))

Hi all, thanks for the help offered.

With the various tips provided I have managed to solve this one now, but in the worksheet, not in VBA.

If anyone wants it I will be happy to forward the spreadsheet. Contact me at denniskb@ozemail.com.au

### RE: Finding Fridays

Dennis,

If you or anyone else is interested, here are some VBA functions that do what you required.  These can be used as worksheet functions in addition to being called from within a VBA procedure.  Supply a valid date as the argument (or cell reference containing a date).  These will convert a Date+Time input and return a Date only value.  There are a couple of additional functions here that the others require but could also be used directly.  The Demo_DateFunctions procedure just demonstrates usage of these functions.

Sub Demo_DateFunctions()
MsgBox "First Friday after date: " & FirstFridayAfterDate(ActiveSheet.Range("A1"))
MsgBox "First Friday of Month: " & FirstFridayOfMonth(ActiveSheet.Range("A1"))
MsgBox "Last Friday of Month: " & LastFridayOfMonth(ActiveSheet.Range("A1"))
End Sub

Function FirstFridayAfterDate(ByVal DateVal As Date) As Date
Dim WkDay As Integer

DateVal = Int(DateVal)
WkDay = Weekday(DateVal)
If WkDay = 6 Then
FirstFridayAfterDate = DateVal + 7
ElseIf WkDay = 7 Then
FirstFridayAfterDate = DateVal + 6
Else
FirstFridayAfterDate = DateVal + 6 - WkDay
End If
End Function

Function FirstFridayBeforeDate(ByVal DateVal As Date) As Date
Dim WkDay As Integer

DateVal = Int(DateVal)
WkDay = Weekday(DateVal)
If WkDay = 7 Then
FirstFridayBeforeDate = DateVal - 1
Else
FirstFridayBeforeDate = DateVal - (WkDay + 1)
End If
End Function

Function FirstFridayOfMonth(ByVal DateVal As Date) As Date
Dim Mnth As Integer
Dim Yr As Integer
Dim DateTmp As Date

DateVal = Int(DateVal)
Mnth = DatePart("m", DateVal)
Yr = DatePart("yyyy", DateVal)
DateTmp = DateSerial(Yr, Mnth, 1)
If Weekday(DateTmp) = 6 Then
FirstFridayOfMonth = DateTmp
Else
FirstFridayOfMonth = FirstFridayAfterDate(DateTmp)
End If

End Function

Function LastFridayOfMonth(ByVal DateVal As Date) As Date
Dim Mnth As Integer
Dim Yr As Integer
Dim DateTmp As Date

DateVal = Int(DateVal)
Mnth = DatePart("m", DateVal)
Yr = DatePart("yyyy", DateVal)

DateTmp = DateSerial(Yr, Mnth, DaysInMonth(Mnth, Yr))
If Weekday(DateTmp) = 6 Then
LastFridayOfMonth = DateTmp
Else
LastFridayOfMonth = FirstFridayBeforeDate(DateTmp)
End If

End Function

Function DaysInMonth(ByVal Month As Integer, ByVal Year As Integer) As Integer

Select Case Month
Case 2
If IsLeapYear(Year) Then
DaysInMonth = 29
Else
DaysInMonth = 28
End If
Case 4, 6, 9, 11
DaysInMonth = 30
Case Else
DaysInMonth = 31
End Select

End Function

Function IsLeapYear(Year As Integer) As Boolean
IsLeapYear = (Month(DateSerial(Year, 2, 29)) = 2)
End Function

Mike
