Maybe...

If you use =hyperlink() in an adjacent cell.

=HYPERLINK("C:\my documents\excel\book2.xls#"&"'"&TEXT(A1,"m-d")&"'!A1")

For example, if the tab of the link is 2-5, and the date in column A is
2/5/06, we want to link to ='[book2]2-5'!. Where 2-5 also corresponds to
=month(A1)&"-"&day(A1), therefore changing the link to the tab associated
with the date in A1, then A2, etc. Can we use a "formula" (month, day,
etc.), in a link?
