If you need to attend training, have a sick day or are just taking time off you will want to block this time out of your diary without having to modify your diary’s schedule overall.
Once you have configured your location, go to edit this via settings, then select to add a break time. When you are presented with the dropdown, select “Specific Date” per the image below

You can then block this time off safe in the knowledge that the system will reject any bookings for this time and allow you to take the time off. You can continue to add dates in the future if you know you need to block off several times in advance.
