title: calendar repeat event weekly
body: <p>does anyone know of a jquery plugin that tell you how many times to repeat an event based on the started and ended date?</p>
  
  <p>I was trying to calculate it myslef, but so far luck :(</p>
  
  <pre><code>var cur_dayofweek = calEvent.start.getDay(),
      org_start_date = calEvent.start.getDate(),
      org_end_date = $( '.j-date' ).datepicker( "getDate" ).getDate(), 
      recurring = Math.round(org_end_date/org_start_date);
  </code></pre>
  
  <p><em><strong>recurring is wrong.</em></strong></p>
  
  <p>Any idea of how can i get this to work or any useful plugin that i can use for it?</p>
  
  <p>NOTE: I'm using jquery-week-calendar plugin</p>
