# forceEventDuration

A flag to force assignment of an event's `end` if it is unspecified.

<div class='spec'>

Boolean, *default:* `false`

</div>

If an event's `end` is not specified, it will be calculated and assigned to the [Event Object](event-object.md) using [defaultTimedEventDuration](defaultTimedEventDuration.md) or [defaultAllDayEventDuration](defaultAllDayEventDuration.md).
