The following does what you want (safely) using only core modules and core functions: 

use POSIX       qw( strftime );
use Time::Local qw( timelocal timelocal_nocheck );

my $start = timelocal(0, 0, 0, (localtime)[3,4,5]);  # Today
my $end   = timelocal(0, 0, 0, 1, 3-1, 2006);        # March 1st, 2006

my $date = $start;

while ($date <= $end) {
   my @date = localtime($date);

   my @tomorrow = @date;
   $tomorrow[3]++;
   $date = timelocal_nocheck(@tomorrow);

   my $wday = $date[6];
   next if $wday == 0 || $wday == 6;  # Weekend

   # Date in locale-specific format.
   print(strftime('%x', @date), "\n");
}

Time::Local
POSIX
localtime

The code could be optimized to only call localtime and timelocal to find the last day of the month and the first day of next month. However, the added complexity to the code is not likely to be worth the savings.
