An applicable scenario is to allow units to declare (independently of
their actual event state) whether they should be deemed as matching a search
based on the dates of the search. For example, a hotel room can declare that it
should be unavailable if the check-in time is not at least 2 days away from the
today.

// until 2 days from now, and not after six months.
$sd = new \DateTime('2016-01-03 00:00');
$ed = new \DateTime('2016-06-01 00:00');

// Test an event starting on the second.
