Hi all.

I'm hoping you can help me with a formula to count the number of specific days between dates.

For example, i have two dates in two cells

A1 = 20/08/11
B1 = 20/09/11

I have a third column with a specific day

C1 = Monday

Is there a formula i can use to calculate how many "C1"s there were between "A1" and "B1"??

Any help is greatly appreciated :biggrin:

Thanks
 

Excel Facts

Format cells as date
Select range and press Ctrl+Shift+3 to format cells as date. (Shift 3 is the # sign which sort of looks like a small calendar).
If C1 is an actual text string "Monday"

Try

=SUMPRODUCT(--(TEXT(ROW(INDEX(A:A,A1):INDEX(A:A,A2)),"dddd")=A3))

USE VBA


Code:
Sub test()
Dim dStart As Date
Dim dEnd As Date
Dim iDateCount As Integer
dStart = RANGE("A1").VALUE
dEnd = RANGE("B1").VALUE
 
Do Until dStart = dEnd
  dStart = dStart + 1
  If Weekday(dStart) = WEEKDAY(RANGE("C1")).VALUE Then
    iDateCount = 1
  End If
Loop
 
 RANGE("D1").VALUE = IDATECOUNT
End Sub
