To count times that occur within a certain range, you can use the COUNTIFs function. In the example shown, the formula in E7 is:

=COUNTIFS(B5:B11,">="&E5,B5:B11,"<"&E6)

The COUNTIFS function takes one or more criteria, entered as range/criteria pairs. In this example, the first range/criteria pair is:

B5:B11,">="&E5

Matching any time greater than or equal to the time E5 (5:00).

The second range/criteria pair is:

B5:B11,"<"&E6

Matching any time less than the time in E6 (6:30).

The formula in E7 could be written with hard-coded time values as follows:

=COUNTIFS(B5:B11,">=5:00",B5:B11,"<6:30")

Excel translates a string like "5:00" into the correct numeric time value.

The formula in E7 could be written with the TIME function like this:

=COUNTIFS(B5:B11,">="&TIME(5,0,0),B5:B11,"<"&TIME(6,30,0))

The TIME function provides a simple way to assemble a valid time using discreet hour, minute, and second values.
