Assume dates are in the range A1:A10

Select the range A1:A10
Goto FormatConditional Formatting
Formula is: =A1=TODAY()
Click the Format button and select the style you'd like
OK out

Assume I have a column of dates. I want that column to be conditionally
formatted so that today's date will be red for example. I enter

=NOW()=1

in the formula for the conditional format but she no go. I tried TODAY
(), etc too.

Any ideas?

Yep, it works. Thanks, Biff!

Anyone care to enlighten me why it works? I don't understand why the
reference to A1 when the whole range is subject to the format.
