The class and session times screen is for you to specify the times that classes, appointments, or workshops can be scheduled. These values are added to start and end time drop down menus throughout your MINDBODY Site.
A Resource Scheduling item appears when you have enabled the resource schedule on your site. The times in this list are updated automatically based on the available times for reservations/enrollment and appointments.
For example, if a start or end time for a class is 5:15 PM; check the box in the 5:00 PM row and 15 column. See figure below.
Class and session (appointment) times can be easily added or removed at any point by following the steps outlined above.
