Not in the same year in my case.

Hi Turk,

If all data belong to the same year you could try the following formula to
get the sum for January:

=SUMPRODUCT(--(MONTH($A$1:$A$6)=1),$B$1:$B$6)

otherwise:

=SUMPRODUCT(--(MONTH($A$1:$A$6)=1),--(YEAR($A$1:$A$6)=2005),$B$1:$B$6)

or

=SUMPRODUCT(--(TEXT($A$1:$A$6,"mmyy")="0105"),$B$1:$B$6)

etc.

You can also replace =1 with a reference to the cell that contains the
number of the month, e.g.

=SUMPRODUCT(--(MONTH($A$1:$A$6)=D1),$B$1:$B$6)

Regards,
KL
