Date::Calc will allow you to roll you own solution for any date manipulation you care to think of. It's written in C too, so is quick. My solution assumes the date format you've defined, so is less flexible than your other answers, but should run quicker.

#!/perl -w
use Date::Calc qw(Add_Delta_Days);
use strict;

print join(',', get_dates('2005-08-29', '2005-09-02'));

#==============================================================
sub get_dates {
    my ($from, $to) = @_;

    my @return_dates = $from;
    my $intermediate = $from;

    while ($intermediate ne $to) {
        $intermediate =  sprintf "%04d-%02d-%02d", Add_Delta_Days(spli
+t(/-/, $intermediate), 1)  ;
        push @return_dates, $intermediate;
        
    }
    return @return_dates;
}
