Here is a sample script that shows how to do this using the DateTime module. There are probably shorter ways of doing the same thing, but this shows you a small bit of the power of the DateTime module, which can do pretty much anything you ever want to do with dates.
#!/usr/bin/perl
use strict;
use warnings;
use DateTime;
use DateTime::Format::Strptime;
my $formatter = DateTime::Format::Strptime->new(
pattern => '%a, %d %b %Y'
);
my $today = DateTime->now( formatter => $formatter );
my @days = ();
foreach my $day (1..14) {
push @days, $today->clone->add( days => $day );
}
print join("\n", @days), "\n";
