Instead of keeping the experience turn on all the time, you can schedule experience to turn_on at a particular date-time and turn_off at a particular date-time. To schedule an experience, click on the experience which you wish to schedule. In the experience targeting tab, at the bottom you can see a button "Add schedule" click on it. Select the start date-time and end date-time as shown below.
Keep the following points in your mind while you are scheduling an experience :
The start date-time should be before end date-time.
The start date-time cannot be empty.
The end date-time cannot be empty.
The start date-time should be after the current date-time.
