titleFormat - Fullcalendar

Determines the text that will be displayed in the header's title.

<div class='spec' markdown='1'> [format string](date-formatting-string), *default*:

'MMMM YYYY'   // like 'September 2009', for month view
'MMM D YYYY'  // like 'Sep 13 2009', for week views
'MMMM D YYYY' // like 'September 8 2009', for day views

</div>

As noted above, each view has a specific default. Get fine-tuned control with View-Specific Options. A single string alone will set the value for all views.

The default values will change based on the current locale.
