Disable saturday and sunday in fullcalendar
The value is an array of day-of-week indices to hide. Each index is zero-base (Sunday= 0) and ranges from 0-6. Example: hiddenDays: [ 2, 4 ] // hide Tuesdays and Thursdays hiddenDays: [ 1, 3, 5 ] // hide Mondays, Wednesdays, and Fridays. By default, no days are hidden, unless weekends is set to false.
