Oops! I "translated" your formula incorrectly for my worksheet. Column A
contains the formula, Column B contains the date, Row 1 is a Header Row. Now
the values are listing sequentially with this formula:
=B2+COUNTIF(B$2:B2,B2)/100

However, now there's an error message displaying for some of the cells
containing the formula. The error message says: "the formula in this cell
refers to a range that has additional numbers adjacent to it". Did I still do
something wrong in translating the formula to fit my worksheet? I have
Columns A thru Q, some of which have numbers and others that contain text,
and some contain other formulas.

Thanks so much for your help.

Thanks for your quick reply, T. Valko. You are correct, there should never
be
more than 99 instances of the same date (far less, I'm sure!)

However, I tried the formula and it numbers every instance of the date the
same. I need the numbers to be unique for every instance:
38116.01
38116.02
38116.03
and so on...

Do you think this is possible?

If there are more than 100 instances then the date will advance after
38116.99

I'm guessing that that is not a possibility?

=A1+COUNTIF(A$1:A1,A1)/100

Copy down as needed. Format as GENERAL to get the serial number.

Here's what I'm trying to do:
Using Excel's date serial numbers, create a unique value for every
instance
of the same date in a column.

For instance, if there are two instances of the date 5/9/2004 in the
same
column, then I want to display a value similar to this in the same row
of
a
different column: 38116.01 for one instance, and with the next instance
having this value: 38116.02. This value should increase incrementally
by
.01
every time a new instance of the same date is added to the column.

I hope this makes sense and that it's possible with a formula, not a
macro.
Thanks in advance for your help!
