title: Jquery Calendar Disable Past Month Issue
body: <p>I have a Jquery Calendar in html. It's display From and To date. following is my code:</p>
  
  <p><strong>html head section code:</strong></p>
  
  <pre><code>&lt;link rel="stylesheet" href="jquery/jquery.ui.all.css"&gt;
  &lt;script src="jquery/jquery-1.9.1.js"&gt;&lt;/script&gt;
  &lt;script src="jquery/jquery.ui.core.js"&gt;&lt;/script&gt;
  &lt;script src="jquery/jquery.ui.widget.js"&gt;&lt;/script&gt;
  &lt;script src="jquery/jquery.ui.datepicker.js"&gt;&lt;/script&gt;
  &lt;link rel="stylesheet" href="../demos.css"&gt;
  
  
  &lt;script&gt;
  
  $(function() {
      $( "#from" ).datepicker({
          defaultDate: "+1w",
          changeMonth: true,
          numberOfMonths: 1,
          onClose: function( selectedDate ) {
              $( "#to" ).datepicker( "option", "minDate", selectedDate );
  
  
          }
      });
      $( "#to" ).datepicker({
          defaultDate: "+1w",
          changeMonth: true,
          numberOfMonths: 1,
          onClose: function( selectedDate ) {
              $( "#from" ).datepicker( "option", "maxDate", selectedDate );
          }
      });
  });
  &lt;/script&gt;
  </code></pre>
  
  <p><strong>html body code:</strong></p>
  
  <pre><code>&lt;label for="from"&gt;From&lt;/label&gt;
  &lt;input type="text" id="from" name="from" class="tr"/&gt;
  &lt;label for="to"&gt;to&lt;/label&gt;
  &lt;input type="text" id="to" name="to" class="tr"/&gt;
  </code></pre>
  
  <p>Well, it's working fine. But is it possible to disable the past month to the filed name <strong>from</strong> ? I just want user can't select previous month to the <strong>from</strong> field.</p>
  
  <p><strong>How the calendar is working Now :</strong>
  If user select From date i.e 18-05-2013 then To date start with 18-05-2013, If its 20-08-2013 then to date start with 20-08-2013. </p>
