Yes, you are :)

There are a couple of optimisations you can make here. Firstly, you have may constructs like:

for ('something' .. 'something else') {
my $var = $_;

[download]

where you can use:

for my $var ('something' .. 'something else') {

[download]

Secondly, and more importantly, at each level you initialise the elements to empty lists, with code like:

$bucket{$x}{$y} = ();

[download]

But on the next level down ,you overwrite it with an reference to a hash. The initial assignment is unnecessary.

In fact, you can simply the whole thing to:

for my $month ('02'..'03') {
  for my $day ('00' .. $mons{$month}) {
    for my $hour ('00' .. '24') {
      for my $minute ('00' .. '59') {
        $bucket{$month}{$day}{$hour}{$minute} = [0,0];
      }
    }
  }
}
