# removeEventSource

> FullCalendar v1 documentation, for an old release. Web version: https://legacy.fullcalendar.io/v1/removeEventSource
>
> Latest version (v7): https://fullcalendar.io/docs/EventSource-remove.md

Dynamically removes an event source.

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

Events from the source will immediately be removed from the calendar.

Since version 1.5, the `source` parameter has become rather relaxed.
You can provide an event source's Array/URL/Function
**or** you can specify the full [Event Source Object](https://legacy.fullcalendar.io/v1/event-source-object.md).

Prior to version 1.5, things were more strict.
You must specify a reference to the original Array/URL/Function.
