Blocked time stops patients booking those slots online and shows as busy on the diary. Click an empty slot on Admin → Calendar to book a patient or mark someone busy. Click an existing busy block to edit it, or switch to Book appointment to save a patient visit at that time — staff can book over Mark busy; online booking still cannot. For longer leave or bank holidays, use Settings → Team — see Book staff time off.
Book an appointment from the calendar
- Open Admin → Calendar.
- Click or drag on an empty slot to open the booking panel.
- Choose Add appointment.
- Select the service, then Location and Clinician when you have multiple sites or bookable people.
- Find or add the patient, then save.

Mark busy on the calendar
- Click or drag on an empty slot on Admin → Calendar.
- Choose Mark busy.
- Select Staff to block.
- Location: All locations blocks them everywhere for that time; pick a site to block only there.
- Add an optional reason and save.

Busy blocks from the calendar work the same way as time off in Settings — they respect rotas and stop online booking in the blocked window. Your team can still book a patient over Mark busy from the diary (Edit busy → Book appointment), including when dragging the start-time preview on the calendar.
Note
To close the whole clinic on a bank holiday, use automatic bank holiday blocking in Settings → Team. For one-off clinic closures, add time off for each bookable clinician, or block each person from the calendar.
