Click the calendar at the time and staff you wish to create the break or block.
In the Left hand drawer, click "Block time" or "break" near the top of the menu. The difference between the two is that a break has a selection of either "Lunch" or "Tea break". A block can be named whatever you wish and can quickly be set to all day. Both can be set to repeat.
Either drag your block/break to the duration that you want (or use the drop down).
Select repeat if desired.
Click "Save".
TIP: 💡
If a staff member has break times that vary from day to day, you could create a recurring break everyday, at whatever the most usual time is. On days that are different, you can easily drag the break with your mouse to another time slot.
NOTE:
If you set a recurring break that overlaps with an appointment in the future, there will be a warning to alert you - the appointment will not be affected.
