Within the Diary, you block out times you would like to not having patient bookings. You can do this by going to Diary -> Add Block from the top right hand corner -> Fill in the details of your block -> OK
If you have multiple locations, you will need to ensure you create a block for either one location or ALL locations if you are unavailable at all locations at this time.
The second way to create blocks is to right click into a practitioner column -> Create Block Here. This training video will step you through how to create, click here.
If creating recurring blocks you must use the recurring feature, do not adjust the end date to cover multiple days, this will not block the diary as expected. Please see the screenshot below for how to set a Holiday block from 10am to 6pm every day from the 3/1/23 to the 13/1/23.
