Does the asterisk appear in the formula bar when you select that cell? (or is
it the result of a formula?)

If it does, then that's not from number formatting.

If you're asking about the format|cells|number tab|date category dialog warning:

Date formats display date and time serial numbers as date values. Except for
items that have an asterisk (*), applied formats do not switch date orders with
the operating system.

Then these dates may display differently on pcs that have a different windows
short date format.

But I've never seen this affect data|Filter|autofilter when you do it manually.

what is purpose of asterisk in date format *3/2/07?
when i use advance filter, a line with a date in it formated with the
asterisk gets filtered out, even though the data in the line satisfies all
criteria and should not be filtered out.
why?
