title: Wordpress get posts between date range using a date meta field
body: <p>I have a post type that uses a custom meta field called <code>start_date</code>. I want to be able to get all posts that have a <code>start_date</code> between date1 and date2. I have been able to figure out how to get posts before or after a date using wp_query by declaring the query type as "DATE". </p>
  
  <pre><code>$queryargs = array('meta_key' =&gt; 'start_date', 'meta_value' =&gt; "2016-06-01", 'meta_compare' =&gt; '&gt;', 'type' =&gt; 'DATE','posts_per_page' =&gt; $instance['pastlimit']);
  </code></pre>
  
  <p>This pulls posts with a start_date after the 1st, but i also want to make it limit dates that dont occur after the 1st of the next month. I cant add the same args again as they dont specify the difference in the constraint. Is it possible to alter the query i have to get posts between a date range. </p>
