By default, appointments can only be scheduled inside of your business hours. However, if you prefer to book at any time, regardless of your business or staff working hours, enable off-hours booking.
Notes:
Off-hours booking only applies to the calendars in your account.
Off-hours booking does not extend to your Booking Page. Customers can only schedule appointments inside of your business hours, based on staff availability.
Only account admins can activate off-hours booking. Staff members need to contact an admin or the account owner
