Weekdays in a Month

by Allen Wyatt
(last updated November 21, 2019)


Ever wonder how many of a particular weekday occur within a given month? For some people, it is important to know how many Tuesdays there are in a month. And who doesn't want to know whether a particular month will have four or five Saturdays?

Excel does not include an intrinsic function that you can use to determine the number of times a particular weekday occurs within a given month. You can, however, create your own formulas and functions to accomplish the task.

First, consider the following formula.


The formula relies on a date in A1. This date should be from the month you want "tested." The formula is meant to be copied into a cell in row 2, and then copied to the six cells directly beneath that. For instance, you could copy this formula to the range of cells B2:B8. The first response (B2) is the number of Sundays in the month, the second (B3) is the number of Mondays, and so on.

The drawback to this formula is that it uses the position of the cell containing the formula as part of the formula. This means that the formula must be placed somewhere beginning in the second row.

Another drawback is that the formula is quite long and complex. If you want a shorter formula, then you need to turn to an array formula. One handy formula you can use assumes that you provide three arguments: the year (cell C2), the month (cell D2), and a weekday (cell E2). With these three items, the following formula works great:

DAY(DATE(C2, D2+1, 0))))))=E2, 1, 0))

Remember that this is an array formula, which means that you must enter it by pressing Shift+Ctrl+Enter. In addition, the weekday value you enter in cell E2 must be in the range of 1 through 7, where 1 is Sunday, 2 is Monday, etc.

Another approach—this one not relying on an array formula—is to test the date in cell A1 for whatever weekday is desired, as specified in E2. (Again, a value of 1 through 7, as in the previous example.)


The formula basically checks to see if there is a fifth instance in the month of whatever weekday you are checking. If there is, then the value 5 is returned; if not, then the value 4 is returned. (The formula rightly assumes that there can only be 4 or 5 instances of any given weekday—never less and never more.)

Macro-based solutions are also available. One such solution follows:

Function MonthWeekDays(dDate As Date, iWeekDay As Integer)
    Dim dLoop As Date
    If iWeekDay < 1 Or iWeekDay > 7 Then
        MonthWeekDays = CVErr(xlErrNum)
        Exit Function
    End If
    MonthWeekDays = 0
    dLoop = DateSerial(Year(dDate), Month(dDate), 1)
    Do While Month(dLoop) = Month(dDate)
        If WeekDay(dLoop) = iWeekDay Then _
            MonthWeekDays = MonthWeekDays + 1
        dLoop = dLoop + 1
End Function

You use the function by entering the following in a cell:


In this usage, the first argument (cell A1) contains a date in the month being evaluated. The second argument is a numeric value representing the weekday that you want to count. This value must be in the range of 1 to 7, where 1 is Sunday, 2 is Monday, and so on.

Oops! I should have mentioned that for this formula the date in A1 has to be the first of the month (01/10/2014, 01/01/2015, 01/04/2015...). It's more than a year ago that I "played" with those formulas so I forgot about that :-(

When I looked at the first formula in this tip I thought, Leonardo da Vinci's saying "simplicity is the ultimate sophistication" in mind, there has to be a simpler solution. In fact all you have to do is check if a fifth instance of a particular day is still in the same month.


Note that this formula can be entered anywhere in the sheet and copied down 6 rows.

This same formula can even be used in the macro that becomes also much smaller:

Function MonthWeekDays(dDate As Date, iWeekDay As Integer)
If iWeekDay < 1 Or iWeekDay > 7 Then
MonthWeekDays = CVErr(xlErrNum)
Exit Function
End If
dDate = DateSerial(Year(dDate), Month(dDate), 1)
MonthWeekDays = IIf(Month(dDate + 35 - Weekday(dDate - iWeekDay)) = Month(dDate), 5, 4)
End Function

@Micky, here are 2 shorter ones and they are even not array formulas:

1) =4+(MONTH(DATE(C2,D2,-WEEKDAY(DATE(C2,D2,1)-E2))+36)=D2)

2) =4+(MONTH(A1-WEEKDAY(A1-E2)+35)=MONTH(A1))

1) There is no need for an IF check.
The Array Formula can look like:
=SUM(N(WEEKDAY(DATE(C2,D2, ROW(INDIRECT("1:" &DAY(DATE(C2,D2+1, 0))))))=E2))

2) If you provide a full date in cell A1 then the formula will look like:
