How do I write an excel formula to count the number of a value in one column based off of a date in another column?

Question

I have a worksheet and I'm trying to do a simple Count function, probably a countif but I'm unsure how to go about writing the formula.

I have two columns that I'd like to use for this formula.

Column N - I would like to filter for the Criteria of "C" or anytime a cell has a value of C

Column 0 - This column has dates filled in (short date format).

I would like to get a count of every C for each month, as simple as that.

In this example I filtered the date for May of 2017 and filtered for C under the Check column. We can see that there are 12 instances of C showing in the month of May 2017.

Does anyone know how to structure a formula that I would be able to Count the Number of C's for every month into the foreseeable future?

I figured out how to count the total present in a date range but unsure of how to add the date range plus Column N (Check) every time "C" is present in the cell.

=SUMPRODUCT((O:O>=DATEVALUE("5/1/2017"))*(O:O<=DATEVALUE("5/31/2017")))

Answer 1

Try this

=COUNTIFS(O1:O100,">="&A1,O1:O100,"<"&B1,N1:N100,"C")

Where A1 has the start date and B1 has the end date for that month. You can use DATEVALUE() instead of A1 and B1 . Change as applicable

If you want to use SUMPRODUCT then see this

=SUMPRODUCT((O:O>=DATEVALUE("1/5/2017"))*(O:O<=DATEVALUE("30/5/2017"))*(N:N="C"))

Answer 2

In another column (lets say 'P' for example) I would insert a formula to give you the month number =Month(P7) - this will return 5 for May.

I would then use COUNTIFS (Like COUNTIF but it uses multiple criteria) to count where column N contains 'C' and column 'P' contains '5'.

=COUNTIFS(N:N,"C",P:P,5)

Try this....you need to select the entire Column B and named the column as 'Date'. enter image description here
