body: <p>I have a custom metabox, where I store the date in plain text like this: <code>dd/mm/yy</code>and now I need to order the posts by that date.The custom field is called <code>event_informations_date</code></p>
  
  <pre><code>&lt;?php
      $args = array( 'post_type' =&gt; 'Event','posts_per_page' =&gt; 1000 );
      $loop = new WP_Query( $args );
