If your date range only goes up to Z1, so there will only be one
column letter returned, then you can simplify my formula considerably
as follows:

=IF(ISNA(MATCH(A2,$B$1:$Z$1,0)),"",CHAR(MATCH(A2,$ B$1:$Z$1,0)+65))

Hope this helps.

Hi there
the dates are in the range sya b1 to z1.
say the date of 01/08/08 is in B1 in the range.
I need to able to enter a date say in A2
and then put a formula in A1 that looks at the date in A2 say 01/08/08 and
returns the column later in this case as B in say a3

Well, here's part of an answer. *This formula will return the column
identifier based on a column number. *In the example, the column number is
assumed to be in cell E4:
=IF(E426,CHAR(CEILING(E4/26,1)+63),"")&CHAR(IF(MOD(E4,26)=0,26,MOD(E4,26))* +64)

The original source for that, I believe, is John Walkenbach. *It handles
anything up to column number 702 (ZZ) which was fine for Excel 2003 and
earlier versions.

To give a more complete solution, I need to know more about where your dates
are at in that range of B1:AH6 - are they in a particular column (in which
case you'd already have the answer) or on a particular row, or is the entire
matrix filled with dates?
