in reply to extracting by date into hour for counting

You want an array and you want it pre-seeeded for the 24 values you're looking for.
my @byhour = (0) x 24; foreach my $hour (@hours) { my ($knownhour) = $hour =~ /\s(\d\d)/; $byhour[$knownhour]++; } print "$_ had $byhour[$_]\n" for 0 .. $#byhour;

Update: Fixed typo caused by not actually trying the code under strict.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.

    I think you have a typo in this. You seem to be calling $hour from the array and $hours in the regex.

    This may be intentional but just something I noticed.
