This is your recurring weekly schedule. Here’s where you can specify your general availability for each day of the week.
Here’s where you can specify exceptions to your schedule. For example, if you’re normally available on Tuesday from 9am-6pm, but next week you’re only available from 9am – 12pm, you can specify your availability for that date here.
If you’re unavailable for an entire day that you’re normally available, you can block off an entire day here.
