Just noticed both of your posts @katja!
Custom or weekly schedules aren't currently available with Square Appointments. Once hours are set, they'll apply to your calendar universally until they're updated.
As a workaround, you can set bookable hours around your regularly scheduled hours with a calendar event.
I’d suggest opening Joe’s availability shortly before Bob’s vacation and blocking off that day in the future to ensure that clients can’t book too far in advance.
I hope this helps, but let me know if you have other questions.
