What have you tried so for?

I tried the following
varWeekendDays = (DateDiff(Interval:="ww", _
date1:=startDate, _
date2:=endDate) _
* ncNumberOfWeekendDays) _
+ IIf(DatePart(Interval:="w", _
Date:=startDate) = vbSunday, 1, 0) _
+ IIf(DatePart(Interval:="w", _
Date:=endDate) = vbSaturday, 1, 0)

Test it:

VB

Option Compare Database
Option Explicit

Sub Test()
Dim dCurDate As Date, dStartDate As Date, dEndDate As Date

dStartDate = CDate("2012-10-16")
dEndDate = CDate("2013-04-15")

dCurDate = dStartDate
Do While dCurDate < dEndDate
    MsgBox Format(dCurDate, "MMMM yyyy") & " has " & GetCountOfWeeks(dCurDate) & " weeks!", vbInformation, "Message..."
    dCurDate = DateAdd("M", 1, dCurDate)
Loop

End Sub


Function GetCountOfWeeks(dInitialDate As Date) As Integer
Dim retVal As Integer
Dim dCurDate As Date, dStartDate As Date, dEndDate As Date

retVal = 0
dStartDate = GetFirstDayInMonth(dInitialDate)
dCurDate = dStartDate
dEndDate = GetLastDayInMonth(dInitialDate)
Do While dCurDate < dEndDate
    If Weekday(dCurDate) = vbSunday Then retVal = retVal + 1
    dCurDate = DateAdd("d", 1, dCurDate)
Loop
GetCountOfWeeks = retVal

End Function


Function GetFirstDayInMonth(dDate As Date) As Date
    GetFirstDayInMonth = DateSerial(Year(dDate), Month(dDate), 1)
End Function

Function GetLastDayInMonth(dDate As Date) As Date
    GetLastDayInMonth = DateSerial(Year(dDate), Month(dDate) + 1, 1 - 1)
End Function
