Wow, thanks

But there still is a problem, that is semi-approx, and he wants semi-exact 

use Date::Manip;
my $dt1="2016080100:00:00";
my $dt2='2016123100:00:00';
my $date1 = new Date::Manip::Date;
my $date2 = $date1->new_date();
$date1->parse($dt1);
$date2->parse($dt2);
my $delts  = $date1->calc($date2,'semi');
my $delte  = $date1->calc($date2,'exact');
my $delve=$delte->value();
my $delvs=$delts->value();

sub semi_exact { 
  my $delve=shift; 
  my @parts=split(':',$delve); 
  my $h0=$parts[4]+$parts[3]*24+$parts[2]*7*24; 
  my $w=sprintf('%d',$h0/(7*24)); 
  $h0=$h0-$w*7*24;
  if ($w<0) {$h0=$h0*-1;}
  my $d=sprintf('%d',$h0/24); 
  $h0=$h0-$d*24;
  my $delvse="0:0:$w:$d:$h0:$parts[5]:$parts[6]";
  return $delvse; 
} # semi-exact 

my $delvse=semi_exact($delve); 
print 'exact      :'.$delve."\n";
print 'semi-approx:'.$delvs."\n";
print 'semi-exact :'.$delvse."\n";


my $fe=DateCalc($dt1,$dt2,0); 
my $fse=semi_exact($fe); 
print 'functional semi-exact :'.$fse."\n";

exit;
