Hi everyone, its been ages since ive been able to post, but it feels good to be back. I hope everyone is well.

So, I have a small request that for some reason I just cant seem to figure out. I need to have excel do a lookup and countif, or some version of those. I have pasted a view of what I am trying to accomplish below, though of course I just did a manual plug and I want to automate with some type of a formula what is shown in the orange cells. Basically I have a list of names and various dates over the course of three months. I need to find a way to lookup the name and then count a date if it falls within a given month. If it lands on any day in that month I want it to be counted. Any help that anyone can provide would be greatly appreciated.

Thanks!

Excel Facts

What is =ROMAN(40) in Excel?
The Roman numeral for 40 is XL. Bill "MrExcel" Jelen's 40th book was called MrExcel XL.
Assuming that Sep-18 is the display form of 2018-09-01, i.e. a first day date...

In B2 enter, copy across to D2, and down:

=SUMPRODUCT(--($F$1:$F$13=$A2),--($G$2:$G$13-DAY($G$2:$G$13)+1=B$1))

Hi!

Another small modification in the suggestion until now:

=SUMPRODUCT(--($F$1:$F$13=$A2),--(--TEXT($G$1:$G$13,"m/yyyy")=B$1))
