コード(TextWrangler)

sample.pl

#!/usr/bin/env perl
use strict;
use warnings;
use utf8;
use 5.012;
use DateTime;
binmode STDOUT, ':utf8';
binmode STDIN, ':utf8';

my $now = DateTime->now;

my($year, $month, $day) = @ARGV;
my $dt = DateTime->new(
  year => $year,
  month => $month,
  day => $day,
);

my $duration = $now - $dt;
my @units = $duration->in_units( qw(years months days));

printf "%d years, %d months, and %d days\n", @units;
