title: FullCalendar - Make date not clickable
body: <p>I'm working with fullcalendar and am wondering if there is a way to make certain dates unclickable. The function I have so far compares all "day squares" dates on the calendar to a maximum date I have defined earlier. If the date goes beyond the max date I add a class to grey them out. They are still clickable. Hiding them screws with the layout of the calendar and looks awful.</p>
  
  <pre><code>            // Grey out the dates that go beyond the maximum availability date 
              var maxParsed = Date.parse(maxDate.toString());
              $("td[data-date]").each(function(){
                  var date = $(this).data('date');
                  var dateParsed = Date.parse(date);
                  if(!isNaN(dateParsed) &amp;&amp; dateParsed &gt; maxParsed){
                      $(this).addClass('fc-other-month');
                  }
              });
  </code></pre>
