# updateEvents

> FullCalendar v3 documentation, for an old release. Web version: https://legacy.fullcalendar.io/v3/updateEvents
>
> Latest version (v7): https://fullcalendar.io/docs/Event-setProp.md

Changes data for multiple events, rerendering them all.

<div class='spec' markdown='1'>
.fullCalendar( 'updateEvents', *events* )
</div>

This method is similar to the [updateEvent](https://legacy.fullcalendar.io/v3/updateEvent.md) method though it accepts an **array of events** as its main argument, to update multiple events at the same time. This reduces the number of event rerenders that must happen, for performance reasons.
