It should definitely be the latter, as "Next month" taking you to 
somewhere else than the next month is confusing. IIRC I have seen JS 
date pickers behave like that, but I am sorry I don't remember where it was.

Even in a rare use case where several months are totally grayed out, the 
user needs the information that no dates are available there - else 
(s)he will assume a technical error or somewhat.
