You can use the Facility Calendar Day View to book new appointments with your Specialists on a 15-minute interval.

When you click on the white fields, the New Event box will pop up and present you with some options:

• Mark Unavailable/Create an Exception is used to block out a specialist for a time frame for all of their services. See the section below "How to set a specialist as unavailable".
  
  
• + New Appointment is used to create a new appointment at that time on that date.
  
  
• Drag an appointment to a different groomer's availability on the same date: You can click and drag an appointment to any other specialist to reschedule the service on the same date. This can be done with time- or slot-based services. 

Important! The specialist must have sufficient availability and a set schedule for that service.

For a specialist that uses a time-based appointment configuration, on the calendar you will see white areas that indicate the available times of the specialist. You can choose any time on a 15-minute interval (i.e. on the hour, half-hour, or quarter-hour).

If the specialist is slot-based, click any green slot opening to book an appointment for that groomer on that date. You can then pick the service. If you wish to pick the drop off/pick up times for slot-based appointments, you will need to schedule the appointment from the new appointment page rather than the facility calendar.
