Excel/Alternative to too many nested IF statements


Hi there,

I have a formula that attempts to look at a column and return an "age" value based on a date range. Pretty straightforward, and I know it works.  However, this particular formula exceeds the max number of IF statements for one cell.  I'm looking for an alternative way to write it that fits in one cell, but I'm coming up short.  

Here is the formula...

=IF(AND(C3>=DATE(2010,9,1),C3<=DATE(2011,8,31)),5 , IF(AND(C3>=DATE(2009,9,1),C3<=DATE(2010,8,31)),6, IF(AND(C3>=DATE(2008,9,1),C3<=DATE(2009,8,31)),7, IF(AND(C3>=DATE(2007,9,1),C3<=DATE(2008,8,31)),8,IF(AND(C3>=DATE(2006,9,1),C3<=DATE(2007,8,31)),9, IF(AND(C3>=DATE(2005,5,1),C3<=DATE(2006,8,31)),10 , IF(AND(C3>=DATE(2004,5,1),C3<=DATE(2005,4,30)),11 , IF(AND(C3>=DATE(2003,5,1),C3<=DATE(2004,4,30)),12 , IF(AND(C3>=DATE(2002,5,1),C3<=DATE(2003,4,30)),13 , IF(AND(C3>=DATE(2001,5,1),C3<=DATE(2002,4,30)),14 , IF(AND(C3>=DATE(2000,5,1),C3<=DATE(2001,4,30)),15 ,special))))))))))))

Anything you can do to help would be great!

First, this piece:
doesn't seem to be right - I think you want the end to be 2006,4,30

But the real problem is that you need to enter all the info in reverse order in the sheet and have a table like this (which in my example is in range F3:G13):
5/1/2000   15
5/1/2001   14
5/1/2002   13
5/1/2003   12
5/1/2004   11
5/1/2005   10
9/1/2006   9
9/1/2007   8
9/1/2008   7
9/1/2009   6
9/1/2010   5

and use VLOOKUP:
