Assuming you have 1/1 in C1 and 1/5 in C2:
=SUMPRODUCT((A1:A1000=C1)*(A1:A1000<=C2);B1:B1000 )

I have been trying to sum cells between two dates.
A B
1/1 8
1/2 8
1/3 8
1/4 8
1/5 5
1/6 7
1/7 9


For example what would I do if I wanted the sum of values in column B
between 1/1 and 1/5. I have years worth of data and a lot of different
intervals. Any help would be appreciated. Thanks in advance
