To book long holidays such as annual leave in the Calendar, use appointment reasons.
Firstly add a new appointment reason, called "holidays" or "annual leave". You need to be have Level 4 (Administrator) permissions to do this.
Our helpful webpage on Setting up new appointment reasons will guide you.
Set up your appointment reason
Create a new appointment in the calendar for the practitioner that blocks out the whole day.
This will allow you to remove any lunch appointments at the same time. The appointment then becomes a full solid block for the day.
You can also see if patients need to be cancelled, or rearranged and deal with them. Our helpful webpage on Cancelling and moving appointments will guide you here.
