How to filter by date using ACF?

Question

WordPress

Greetings. I'm trying to filter posts by date, you need to get posts at least for a certain date first. Here, I wrote the code, but the result is that there are no posts, although there is a post for this value.
Question: what am I doing wrong?

$the_query = new WP_Query(array(
          	'post_type'			 => 'post',
          	'posts_per_page' => -1,
          	'orderby'			   => 'calendar_date',
          	'order'				   => 'ASC',
            'cat'            => '26',
            'meta_query' => array(
                              array(
                                'key' => 'field_5b48f1dbc5529',
                                'value' => '16.07.2018'
                              )
                            )
                          
          ));
          while ( $the_query->have_posts() ) : $the_query->the_post();

Try not through the meta_query array, but through the parameters:
'meta_key' => '',
'meta_value' =>'',

and if a date is selected, it must also be in the date format .
