# Insert an end time in an existing ad avail
<a name="insert-an-end-time-in-an-existing-ad-avail"></a>

You can insert an end time in the following situations:
+ To add an end time to a message that has not yet started if an end time was not initially included.
+ To cut short an ad avail that is in progress. The command can be used in this way if no end time was initially included or if it was included but you want to end early.
