title: Query posts published after a certain date in Wordpress
body: <p>I'm trying to write a <code>WP_Query</code> where I'm calling only posts that have been posted after march 2012. I can successfully call posts that are just in March 2012, but struggling to do 'from March 2012 onwards'.</p>
  
  <pre><code>    $current_year = date('2012');
      $current_month = date('&gt;3'); // This doesn't work
      $current_month = date('3'); // This DOES work
  
      $custom_query = new WP_Query("year=$current_year&amp;monthnum=$current_month&amp;order=ASC&amp;posts_per_page=-1");
  </code></pre>
  
  <p>Am I missing something simple, or does this have to get more complicated?           </p>
