How to modify
To modify a specific Time Availability period on your calendar, simply click the date and edit the time slot in the drop list. For example, you are no longer available from 16:00-18:00. You may select 16:00 from the drop list to remove the 2 hours on your teacher calendar. If you are no longer available during the whole time slot from 7am to 11am, you may just click the "bin" button to delete the whole time slot. Then click "APPLY TO ALL XXDAYS" if this change should be repeated every week. Click "APPLY TO (THE DATE) ONLY" if this change is a special case for this date only.
You can use Calendar Cleanup to clear up a specific period of availability.
Please note that changing your availability will NOT affect any lessons that have already been booked.
