  JQuery Calender Default Week Start From Mon
  
  This is the default jQuery calender week start from Sun to Sat but I want default Mon to Sat. I am using jQuery Calender.
  
  A:
  
  Use firstDay parameter with 1 when you did initialize the calendar.
  $('#calendar').fullCalendar({              
      firstDay: 1 
  });
  
  Also you can start from other days serially like Sunday=0, Monday=1, Tuesday=2, etc. Complete example,
  
  $(function() {
    $('#calendar').fullCalendar({
      events: 'https://fullcalendar.io/demo-events.json',
      firstDay: 1 
    });
  });
  html, body {
    margin: 0;
    padding: 0;
    font-family: "Lucida Grande",Helvetica,Arial,Verdana,sans-serif;
    font-size: 14px;
  }
  
  #calendar {
    max-width: 900px;
    margin: 40px auto;
  }
  <script src="https://unpkg.com/moment@2.24.0/min/moment.min.js"></script>
  <script src="https://unpkg.com/jquery@3.4.1/dist/jquery.min.js"></script>
  <script src="https://unpkg.com/fullcalendar@3.10.1/dist/fullcalendar.min.js"></script>
  <link href="https://unpkg.com/fullcalendar@3.10.1/dist/fullcalendar.min.css" rel="stylesheet"/>
  <div id='calendar'></div>
