Show week number in FullCalendar

Question

I\'m looking for a way to show the week number on the agendaWeek view. I\'ve tried this method but without result.

Actually, I need to put the number in the calendar tit

Answer 1

I found a way to do this and it works for me :

Place this in the settings :

viewDisplay: function(view) {
      if (view.name == 'agendaWeek')
      {
          $("table.fc-header span.fc-header-title h2").append("
Week " + getWeekNumber(view.start));
      }
   }, // others settings...

Place this in the same file, before the fullcalendar settings

function getWeekNumber(d) {
  d = new Date(d);
  d.setHours(0, 0, 0);

  d.setDate(d.getDate() + 4 - (d.getDay() || 7));

  const yearStart = new Date(d.getFullYear(), 0, 1);

  const weekNo = Math.ceil(((d - yearStart) / 86400000 + 1) / 7);

  return weekNo;
}

And that's that. Thank you for your previous answer, I'm going to try to update my fullcalendar version.
