You can set the interval at which available times are displayed to guests.
For example, if Booking duration is 60 minutes and Interval between available times is 30 minutes, 60-minute available times are displayed every 30 minutes:
9:00–10:00
9:30–10:30
10:00–11:00
If Auto is selected, available times are displayed at the same interval as the configured booking duration.
You can select 15, 30, 60, or 120 minutes. Under Custom settings, you can set any value from 10 to 120 minutes in one-minute increments.
Changing the interval does not change the duration of each available time.
