Block types are the labels on non-patient time: Lunch, Day Off, Sick Leave. A short list with distinct colors keeps the calendar readable at a glance.
What a block type is for
Every unavailable block on the calendar has a type, and the type is what everyone else reads: Lunch, Annual leave, Admin, Training. A new clinic starts with Lunch (60 min), Day Off (8 h) and Sick Leave (8 h). Keeping the list short and the colors distinct means a glance at a column tells you why the time is out. Open Settings, then Unavailable Blocks.
This list is one for the whole clinic; every location uses it, and there's nothing to set up again when you add a location.
Add or change a type
Name
Shown on the block itself and in the booking warning staff see, as in Overlaps Annual leave (09:00–17:00), so keep it plain.
Duration
The length a new block of this type starts with. Set Lunch to 45 minutes and Annual leave to a full day, and staff rarely need to adjust the end time.
Color
The color of the block on the calendar. Choose something that doesn't clash with your main appointment types.
Retire a type
Archive a type you no longer use. Blocks already on the calendar keep their name and color; the type isn't offered for new blocks. Unarchive it to bring it back.
