Calculating the number of entries between 2 times

[Bonzai]

I am working on a Dispatch records workbook. I am trying to get counts of
entries between 2 time frames. Example, How many entries between 8:00AM and
9:00AM, 9:00AM and 10:00 AM etc. I can get counts using less than, more than,
and equal, but not have had much luck with getting counts between 2 values. I
would like to also get response times(the time the call is received to when
it is dispatched) between 2 times. Any suggestions?

Ok, the first thing you have to do is to better define the time intervals.

8:00 AM to 9:00 AM
9:00 AM to 10:00 AM

So, if the time is 9:00 AM which interval does that fall in?

You might want to use these for the time intervals:

8:00 AM to 8:59 AM
9:00 AM to 9:59 AM
10:00 AM to 10:59 AM

Or, you could use these:

8:01 AM to 9:00 AM
9:01 AM to 10:00 AM
10:01 AM to 11:00 AM

A1:A100 = times to be counted

Use cells to hold the time boundaries for the interval:

C1 = lower boundary = 8:00 AM
D1 = upper boundary = 8:59 AM

=COUNTIF(A1:A100,">="&C1)-COUNTIF(A1:A100,">"&D1)

P.S.

Excel, trying to be "helpful", may show the result of the formula as a date.
Just change the format to either General or Number.
