Here's an example solution (including error checking) using the
Date::Calc module:
my $start_date = "2005-07-12";
my $end_date = "2005-08-03";
use Date::Calc qw/Delta_Days Add_Delta_Days check_date/;
my @start_date = split /-/, $start_date;
my @end_date = split /-/, $end_date;
die "Bad start date" unless check_date(@start_date);
die "Bad end date" unless check_date(@end_date);
die "bad order" unless Delta_Days(@start_date, @end_date) >= 0;
my @d = @start_date;
while( Delta_Days(@d, @end_date) >= 0 ){
printf "%04d-%02d-%02d\n", @d;
@d = Add_Delta_Days(@d, 1);
}
