When a [dayGrid view](daygrid-view) is programmed to span across months, the text format for the first cell of each month.

<div class='spec'>

[format string](date-formatting), *default*: `&#123; month: 'long', day: 'numeric' &#125;`

</div>

The default format will yield something like "January 1".
