in reply to splitting a string into arbitrary lengths

You could do it with a regex as well:

my ($tyear, $tmon, $tday) = ($today =~ /(\d{4})(\d{2})(\d{2})/);
This would be a good route if you had a less standard format, like optional dashes.

    That is what I'd perhaps use too, depending on the application. If I'd chose this way I'd even tag along a success check (and add anchors). Your format may change some day and then you'll be glad you caught that.

    my ($y, $m, $d) = $today =~ /^(\d\d\d\d)(\d\d)(\d\d)\z/ or die "Incorrect date format: '$today'";
