Try

=COUNTIF(A:A,"<10:30:00")

=COUNTIF(A:A,"<12:30:00")-COUNTIF(A:A,"<10:30:00")

Try

=COUNTIF(A:A,"<10:30:00")

=COUNTIF(A:A,"<12:30:00")-COUNTIF(A:A,"<10:30:00")

Hi Xld

Then why is <10:30 returning 4 in your example?

Sure, try this array formula

=COUNT(1/FREQUENCY(IF(($A$2:$A$100>--"00:00:00")*($A$2:$A$100<=--"10:30:00"),IF($A$2:$A$100<>"",$A$2:$A$100)),IF(($A$2:$A$100>--"00:00:00")*($A$2:$A$100<=--"10:30:00"),IF($A$2:$A$100<>"",$A$2:$A$100))))

Just change the time thresholds to suit
