Aas I mentioned above, It is not possible to cease accepting bookings after a certain date. If we book it for ourselves then airbnb service fee will be applied. If we have a 3 months window or 1 year window then the date after the 3 months or 1 year is already blocked . We cannot block it on top of that. But as the week passes, another week opens and we cannot always manually keep track of it(of blocking it). So this is a bad system inplace. The only way to overcome this , for me atleast, is to put an exorbitant amount for the dates you dont want the booking to happen. So even if they automatically opens up, no one will book it
