Pick any one of those :)

Or here is an *untested* example without them :)


use POSIX qw(mktime strftime);

my $input= 30/11/2004-04/11/2004
my @output;

my ($start_day, $start_month, $start_year,
      $end_day,   $end_month,   $end_year) = split /[\/-]/, $input;

my $date = mktime(0,0,12,$start_day, $start_month-1, $start_year-1900);
my $end  = mktime(0,0,12,  $end_day,   $end_month-1,   $end_year-1900);


while ($date <= $end) {
   push @output, strftime("%d/%m/%Y|%A" , localtime $date);
   $date += 60*60*24;
}


I am sure this suffers when changing Day Light Saving Time.
