Matching numbers witin a series

[Guest]

A3 and A4 contain from and to dates.

B1 and B2 contain Year one start & Finish (eg 1/1/05 and 31/12/05)
Subsequent Colums contain subsequent years.

I need help in trying to establish how many days within the dates specified
in A3 and A4 are also contained within the periods specified in each column.

I am using Microsoft Office XP.

Hi!

If I understand correctly:

=SUMPRODUCT(--(ROW(INDIRECT(B1&":"&B2))>=$A3),--(ROW(INDIRECT(B1&":"&B2))<=$A4))

Copy across as needed.
