Calculate number of codes betwen dates

[Danielah21]

I need to calculate amount of times certain code appears through my
worksheet between certain dates, e.g. how many times did DH (or KN) appear in
Sept)

KN 30/09/08
KN 10/10/08
DH 03/09/08
MG 03/09/08
PM 15/10/08
DH 14/09/08


I have tried dsum, sumif, array formulas, nothing seems to like dates

 

[David Biddulph]

=SUMPRODUCT((A2:A7="KN")*(MONTH(B2:B7)=9))

 

[~L]

And with DH too:
=SUMPRODUCT(((G17:G22="KN")+(G17:G22="DH"))*(MONTH(H17:H22)=9))

Sorry, i tried something similar previously and also tried your suggestion,
still nothing. Almost doubt my excel is working as nearly all formulas are
coming with errors

Sorry, my fault, I was using USA date format Thank you, it did work

Hi,

You can also try this array formula (ctrl+Shift+Enter)

=COUNT(IF((MONTH(B11:B16)=9)*(A11:A16="KN"),1))
