A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The formula that worked for me was
=COUNTIFS(C2:C434,">=1/1/2021",C2:C434,"<=1/31/2021",A2:A434,"BB")
Wonderful!
(It is not working for Me though.)
Another alternative could be: =COUNTIFS(C2:C434,">=1/1/2021",A2:A434,"BB")-COUNTIFS(C2:C434,">31/1/2021",A2:A434,"BB")
