weekNumbers

Determines if week numbers should be displayed on the calendar.

<div class='spec' markdown='1'> Boolean, *default*: `false` </div>

If set to true, week numbers will be displayed in a separate left column in the Month/DayGrid views as well as at the top-left corner of the TimeGrid views. View a simple demo.

By default, FullCalendar will use the current locale's week number calculation method. To display other types of week numbers, see weekNumberCalculation.
