Hello Ismael,


Let's look at the following ...

To count all occurancces:


=COUNT($C$4:$D$96)


To count all occurances under your Max limit:


=COUNTIF($C$4:$D$96,"<"&C2+10/1440)


To count all occurances under your Min limit:


=COUNTIF($C$4:$D$96,"<"&C1+10/1440)


To count all occurances that intersect your Min/Max values:


=COUNTIF($C$4:$D$96,"<"&C2+10/1440)-COUNTIF($C$4:$D$96,"<"&C1+10/1440)
or

=SUMPRODUCT(--($C$4:$D$96<C2+10/1440),--($C$4:$D$96>C1+10/1440))


I would do something like naming the range (and unmerging the cells also!) with a name like 'rng'. This would take your caculation to ...


=SUMPRODUCT(--(rng<C2+10/1440),--(rng>C1+10/1440))

Note: we must do the "10/1440" as Excel calculates time in fractions of a day, so there are 1,440 minutes in a day.
