I am using fullcalender where I have added validRange property. After adding user won't be able to navigate outside given daterange also fullcalender will show disable those blocks.

But I want to see Date in those disabled colums.

CodePen Demo

calender options:

var calendar = new FullCalendar.Calendar(calendarEl, {
    plugins: [ 'dayGrid' ],
    timeZone: 'UTC',
    height: 'auto',
    events: 'https://fullcalendar.io/demo-events.json?overload-day',
    validRange: {
        start: '2021-05-01',
        end: new Date()
    },
  });

Current Output:

Expected Output:
