For the event calendar we use the fullcalendar plugin, this is a popular plugin for creating event schedules.

How to install ?

                  
<script src="vendors/@fullcalendar/index.global.min.js"></script>

<!-- Calendar Event -->
<script>
const fullcalendars = document.getElementById('calendar');
if ( fullcalendars != null) {
  document.addEventListener('DOMContentLoaded', function() {
    var calendarEl = document.getElementById('calendar');
    var date = new Date();
    var dates = date.getFullYear().toString() + '-' + (date.getMonth() + 1).toString().padStart(2, 0) + '-' + date.getDate().toString().padStart(2, 0);
    var calendar = new FullCalendar.Calendar(calendarEl, {
      initialView: 'dayGridMonth',
      initialDate: dates,
      headerToolbar: {
