You can compare date with strtotime function

$date1=strtotime('2/3/2011');
$date2=strtotime('1/1/2011');

if ($date1 < $date2)
{
   echo '2/3/2011 come first';
}
else
{
   echo '1/1/2011 come first';
}

But be aware of 2038 bug

Unix timestamps cannot deal with dates before Fri, 13 Dec 1901 20:45:54 UTC and after Tue, 19 Jan 2038 03:14:07 UTC

In javascript you can use Date :

var d1 = new Date(2011, 2, 2);
var d2 = new Date(2011, 0, 1);
if (d1 > d2) {
    alert('Date 1 is greater than Date 2');
}
