Letting the clock run its course and not declining or accepting is not to be recommended.
It blocks off the days in question and is Airbnb's reaction this year to too many hosts leaving guest requests hanging.
Not declining/accepting a simple inquiry since this year summer also seems to have a (?stronger?) affect on your search algorithms, I've heard at least. And I think I remember seeing a little check box to keep those dates open. So missing that is not good. But I hardly get any inquiries I absolutely have to turn down.
With requests, of course, it's stricter.
