    One way, using DateTime: 

    use strict;
use warnings;

use DateTime qw( );

my $sdt = DateTime->new(
    year  => 2010,
    month =>    3,
    day   =>    9,
);

my $edt = DateTime->new(
    year  => 2010,
    month =>    3,
    day   =>   16,
);

for (my $dt = $sdt->clone(); $dt<=$edt; $dt->add( days => 1 )) {
    print($dt->ymd(), "\n");
}

        You could use a regex to parse. You could use one of the DateTime::Format modules. 
        use strict;
use warnings;

use DateTime::Format::ISO8601 qw( );

my $sdt = DateTime::Format::ISO8601->parse_datetime('2010-03-09');
my $edt = DateTime::Format::ISO8601->parse_datetime('2010-03-16');

for (my $dt = $sdt->clone(); $dt<=$edt; $dt->add( days => 1 )) {
    print($dt->ymd(), "\n");
}

    You can you this following code for print the date between the range 
    use strict;
use warnings;
 my $command;
foreach(1..5)
{
  $command = "date -d \"+ $_ day\"";
    system ("$command");
}
