Change the name format of the day in the weekly overview

Question

How can I change the date formatting in Fullcalendar → weekview.
Now it says:

Sun 7/24 Mon 7/25 Tue 7/26 Wed 7/27 Thu 7/28 Fri 7/29 Sat 7/30 

I want to change the month and day for him to say

 Sun 24/7 Mon 25/7 Tue 26/7 Wed 27/7 Thu 28/7 Fri 29/7 Sat 30/7 

this is how our users are used to in the country where I live / work.

Answer 1

I found a solution:

 columnFormat: { month: 'ddd', week: 'ddd d/M', day: 'dddd d/M' }, 

Answer 2

An error has occurred, the first character must be lowercase:

c olumnFormat: {month: "dddd", week: "dddd / m", day: "dddd d / m"},

Answer 3

try it then.

 $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,basicWeek,basicDay' }, defaultView: 'basicWeek', editable: true, events: [ { title: 'All Day Event', start: new Date(y, m, 1) // change the format here. }, { title: 'Long Event', start: new Date(y, m, d-5), end: new Date(y, m, d-2) }
