title: WooCommerce Show Product Total Sales after Custom a Date in Frontend
body: <p>I want to show product total sales after custom date:</p>
  
  <p>I have this code, but I would like to custom it for showing only the total sales after a custom date for example <code>05/26/2016</code></p>
  
  <pre><code>function total_sales()
  {
      global $product;
      $units_sold = get_post_meta(206, 'total_sales', true);
      echo '&lt;p&gt;' . sprintf(__('Units Sold: %s', 'woocommerce'), $units_sold) . '&lt;/p&gt;';
  }
  </code></pre>
