How do I get elements using getCriteria from a specific date?
Something like this should work:

$criteria = craft()-&gt;elements-&gt;getCriteria(ElementType::Entry);
$criteria-&gt;section  = 'sectionHandle';
$criteria-&gt;postDate = array('and', '&gt; 2014-11-03 23:59:59', '&lt; 2014-11-05 00:00:00');
$results = $criteria-&gt;find();
