Meant to point out that you will need to adjust the range for your list of
times. It might be easier to use a named range in the formula and then just
use Insert--Name--Define to adjust the area that the name refers to.

Assuming that your range of data starts at A1, the formula you need to count
those between 7am and 8am is:

=COUNTIF($A$1:$A$5,"="&TIME(7,0,0))-COUNTIF($A$1:$A$5,"="&TIME(8,0,0))

To find those between 8am and 9am, simply change the formula to read:

=COUNTIF($A$1:$A$5,"="&TIME(8,0,0))-COUNTIF($A$1:$A$5,"="&TIME(9,0,0))

Apply the equivalent formulae to the other 22 cells so that you have one
formula for each of the 24 hours in the period. Remember to use 13,14,15 etc
for the 24-hour clock.

This should be what you need.

this goes on over 24 hours. military time.

i have tried different formulas, IF,AND,OR functions, i tried conditional
formating. i failed miserably at these. i m to new at excel to know the
nuances. i have done many searches on this forum and found and solved 95% of
the issues in needed to solve. any help would be greatly appreciated. thank
