In the case of Lite or Advanced Plan, the ad budgets are enough to run for a maximum of 30 days duration. However, suppose your event ticket sale is ending before that; in such a case, per day budget will be increased to get better visibility in the available time frame. And if your event ticket sale is ending after 30 days, either we can start the campaign just before 30 days, or we can start early, and you can add extra budget to continue the campaign beyond 30 days.
