> FullCalendar v6 documentation, for an old release. Web version: https://legacy.fullcalendar.io/v6/monthStartFormat
>
> Latest version (v7): https://fullcalendar.io/docs/monthStartFormat.md

The date format for the first cell of each month, when a [dayGrid view](https://legacy.fullcalendar.io/v6/daygrid-view.md) spans several months.

<div class='spec' markdown='1'>
[format string](https://legacy.fullcalendar.io/v6/date-formatting.md), *default*: `{ month: 'long', day: 'numeric' }`
</div>

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