  <pre><code>var source = { events: [
                             {
                               title  : val.xxxxName,
                               start  : val.StartDate,
                               end    : val.EndDate,
                               xxxxDetailID : val.xxxxDetailID,
                            }
                  ]};
  
  $('#calendar').fullCalendar( 'addEventSource', source );
  </code></pre>
  
  <p>I have lots of event for month. I can get all events by using:</p>
  
  <pre><code>$('#calendar').fullCalendar('clientEvents');
  </code></pre>
  
  <p>But I need only one months event ids. </p>
