Are you sure your times are true Excel times? Do the entries also contain
dates, like this 1/1/2009 22:15:00 ? In Excel, time is really a number, the
fractional part of a day (which has a value of 1), formatted to look like a
time entry. 12:00 PM is half a day so half of 1 is 0.5. The true value of
12:00 PM is 0.5.

You can test to see if the entries are true time values by using one of
these formulas:

=COUNT(A1)
=ISNUMBER(A1)

If the entry in A1 is a true Excel time value COUNT will return 1 and
ISNUMBER will return TRUE.

No luck on either of the suggestions. Any other options?

Try these. Assuming no empty cells.

12:00:00 AM to 12:59:59 AM

=SUMPRODUCT(--(HOUR(A1:A10)=0),--(HOUR(A1:A10)<1))

1:00:00 AM to 1:59:59 AM

=SUMPRODUCT(--(HOUR(A1:A10)=1),--(HOUR(A1:A10)<2))

Follow that pattern until you get to

23:00:00 to 23:59:59

=SUMPRODUCT(--(HOUR(A1:A10)=23),--(A1:A10<1))

I am looking to count the number of cells that meet criteria in a 24
hour
clock format.

The cell range is C2:C1395.
If a time falls between 00:00:00 and 00:59:59, I want to count it. This
would continue for the remaining 23 hours

I was able to get this to work at one point using COUNTIF, but now it
is
not
functioning and an error keeps appearing. Also, would it make a
difference
in
the formula if I was using Excel 03 versus 07?

Thanks for any help.
