## 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.

> The first Friday following the given date

> The first 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.

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))

I have put up an Excel sheet which does this.

## RE: Finding Fridays

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.

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)))))

## RE: Finding Fridays

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

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
