Excel should allow calendar based spreadsheet linking.
 

I use several workbooks at a time that are set up monthly that have an
individual spreadsheet for each day. I do fairly complicated data linking in
that I have to change each equation that I copy to the next spreadsheet to
make it link to the appropriate day's sheet in another work book. It would
be helpful if Excel could recognize the pattern in the links on the different
spreadsheets and automatically modify the links for me in the same way you
can drag-copy an equation within a spreadsheet.

Alternatively one could use the existing XL functions that enable a user to
accomplish this task, which include among others:

OFFSET
MATCH
INDEX
COUNT & COUNTA
SUMPRODUCT
SUMIF

And of course there PIVOT TABLES
