The POSIX strftime() function has no problem taking values for the day
that exceed the actual number of days in the given month. When it is
given such a value, it automatically increments the month and/or year
appropriately:
$ perl -MPOSIX=strftime -e'
my $start = "07-20-2007";
my $end = "08-20-2007";
my ($m, $d, $y) = split /-/, $start;
my $date;
do {
$date = strftime("%m-%d-%Y", 0, 0, 12, $d, $m - 1, $y - 1900);
print "$date\n";
$d++;
} until ($date eq $end);
