$arrayStartDate =explode ("/", $myStartDate); 
$arrayEndDate = Explode ("/", $myEndDate);
$jdStartDate = Cal_to_jd (Cal_gregorian, $arrayStartDate [1], $arrayStartDate [0], $arrayStartDate [2]);
$jdEndDate = Cal_to_jd (Cal_gregorian, $arrayEndDate [1], $arrayEndDate [0], $arrayEndDate [2]);
$duration = $jdEndDate-$jdStartDate + 1;
