You may want to spend some time learning about pivottables. You'll be able to
group dates by month (and year) or by year.

If you've never used pivottables, here are a few links:

Debra Dalgleish's pictures at Jon Peltier's site:

And Debra's own site:

John Walkenbach also has some at:

(look for Tony Gwynn's Hit Database)

Chip Pearson keeps Harald Staff's notes at:

MS has some at (xl2000 and xl2002):

Previously I was using a helper column, but that seemed awkward. I believe I
have found the solution: I changed the date format to "March-10" which I
found in Format Cells\Number\date and now subtotal works.

I am considering breaking it down by Year, then by Month within Year using
nested subtotals. For this I might need helper columns? Well, maybe I will
leave it as is.

Thanks for replying so quickly, Dave.

I'm not sure what you're using to subtotal, but if it's dates, then maybe
you
can add a helper column to your data:

=text(a2,"yyyy-mm")
and drag down
(assumes that a real date is in A2)

I have a small database consisting of dates and sales amounts. I would
like
to subtotal the sales amounts for each month. However, no matter what I
do,
Excel subtotals for each day. Is it possible to break this down by month?
I
would appreciate any help. Thank you.
