Do you allow flipping between only the months which have any available
dates in them using the next/previous month buttons in the date
picker?
That would be the idea, I guess, but there are two alternatives
regarding months that have no applicable days: either skip them or gray
them out. So in your example, when in April 2011, "Next month" button
could take you to June 2012, or it might take you to to May 2011 with
all days grayed out
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.
