A setting that determines how long you'd like your campaign's ads to run. When the campaign's end date arrives, your ads will stop running.
The default setting for each ad campaign is to have no end date, so that the ads are able to run indefinitely. You can change the setting at any time to have your campaign end on a specific date. When you select an end date, your campaign will end on that date at 11:59 PM in the time zone that you have chosen for your account.
Before your end date, you can also pause, resume, or remove a campaign at any time to stop the ads from running.
