**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007, 2010, 2013, 2016, 2019, and Excel in Office 365. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Weekdays in a Month.

Ever wonder how many of a particular weekday occurs 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.

=4+N((WEEKDAY(DATE(YEAR($A$1),MONTH($A$1),1)))+ (DAY(DATE(YEAR($A$1),MONTH($A$1)+1,0))-28)>(7*(( WEEKDAY(DATE(YEAR($A$1),MONTH($A$1),1)))>(1+ROW()- ROW($A$2)))+(1+ROW()-ROW($A$2))))

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:

=SUM(IF(WEEKDAY(DATE(C2, D2, ROW(INDIRECT("1:" & 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 great formula you can use is the following:

=NETWORKDAYS.INTL(DATE(YEAR(A1),MONTH(A1),1),EOMONTH(A1,0), REPT("1",B1-1) & "0" & REPT("1",7-B1))

This generalized formula needs only two values to work properly. The first is a date that is within the month you want to analyze; this goes into cell A1. In cell B1 you should place an indicator of the weekday you want to count. This value is different than in the previous formula—while it must still be in the range of 1 to 7, 1 is Monday, 2 is Tuesday, etc.

If your worksheet design doesn't allow for you to enter the year, month, and weekday in different cells, a clean solution is to create a user-defined function to return the count. The following macro is an example of this type of function.

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 Loop End Function

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

=MonthWeekDays(A1,4)

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.

=4+(MONTH(DATE(YEAR(A$1),MONTH(A$1),1)+35-WEEKDAY(DATE(YEAR(A$1),MONTH(A$1),1)-ROW(A1)))=MONTH(A$1))

Note that this formula can be entered anywhere in the sheet and copied down 6 rows provided you adjust the A$1 reference except for ROW(A1) which can be any reference to row 1 such as ROW(H1).

In the third formula the NETWORKDAYS.INT function is used but this is is only introduced in Excel 2010. Here is an alternative for Excel 2007 and below:

=4+(MONTH(DATE(YEAR(A1),MONTH(A1),1)-WEEKDAY(DATE(YEAR(A1),MONTH(A1),1)-E2)+35)=MONTH(A1))

Function MonthWeekDays(dDate As Date, iDay As Integer)

If iDay < 1 Or iDay > 7 Then

MonthWeekDays = CVErr(xlErrNum)

Exit Function

End If

dDate = DateSerial(Year(dDate), Month(dDate), 1)

MonthWeekDays = (4 - (Month(dDate - Weekday(dDate - iDay) + 35) = Month(dDate)))

End Function
