## Count cells based on a condition and month

In A column, there are dates in mmddyyy format and in B column, there are two variables uses either "PASS" or "FIAIL". All I want to do is to count the "PASS" in individual month range.

Can someone help me in it. I am able to count days of month from the column A but can not link it with Column B.

**Answer:**

**Formula in cell C1:**

Copy cell C1 and paste down as far as needed.

### Explaining formula in cell C1

#### Step 1 - Create arrays

The YEAR function returns the year from an Excel date.

=SUMPRODUCT(--(YEAR(A1)=YEAR($A$1:$A$30)), --(MONTH(A1)=MONTH($A$1:$A$30)), --(B1=$B$1:$B$30))

contains three criteria. The first criterion: --(YEAR(A1)=YEAR($A$1:$A$30))

becomes

--(2010=2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010, 2010)

becomes

--(TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE, TRUE)

and creates this array: (1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)

The MONTH function returns a number from 1 to 12 representing the month. Jan = 1, Feb = 2 ... Dec = 12.

The second criterion: --(MONTH(A1)=MONTH($A$1:$A$30))

creates this array: (1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0)

The third criterion: --(B1=$B$1:$B$30)

creates this array: (1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 0, 1, 0, 0, 1, 0, 1)

#### Step 2 - The product of three arrays

The SUMPRODUCT function multiplies the arrays (product) and then add the numbers in the array and returns a total (sum).

The entire formula now becomes

=SUMPRODUCT((1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1), (1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0), (1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 0, 1, 0, 0, 1, 0, 1))

and then

=SUMPRODUCT((1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)*(1, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 0, 0)*(1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 0, 1, 0, 0, 1, 0, 1))

becomes

#### Step 3 - Sum array

=SUMPRODUCT(1, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0) equals 7.

Here is another (slightly shorter) way to write the formula that gets put into C1...

=SUMPRODUCT((TEXT($A$1:$A$30,"mmyyyy")=TEXT(A1,"mmyyyy"))*($B$1:$B$30=B1))

Great work but this is not exactly what I require, I think I was unable to convey my message correctly.

Well, here is it again. Consider the first excel representation with 3 columns A=Date, B=FAIL/PASS & C=count. I don't actually want C with A & B.

In sheet 1, only A & B exist and in sheet 2, it shows like A=Months(January,feb etc) & B=2. Simply it means 2 students pass during January 2010. In sheet 2, there are only 12 cells in A, which are names of months and infront of them, the count of PASS is calculated.

I hope, I have conveyed my message now.

@Janib,

For the count of the passes by month, put this formula next to the January entry on Sheet2 and copy it down...

=SUMPRODUCT((MONTH(Sheet1!A$1:A$1000)=ROW(A1))*(Sheet1!B$1:B$1000="PASS"))

As structured, the formula will handle 1000 data entries on Sheet1... if you need more, just change both 1000's to whatever value you actually might need. If you also want a count of the fails, use the identical formula but change the word "PASS" to "FAIL"
