add_action( 'woocommerce_single_product_summary', 'bbloomer_product_sold_count_1_week', 11 );
  
function bbloomer_product_sold_count_1_week() {
   global $product;
    
   // GET LAST WEEK ORDERS
   $all_orders = wc_get_orders(
      array(
         'limit' => -1,
         'status' => array_map( 'wc_get_order_status_name', wc_get_is_paid_statuses() ),
         'date_after' => date( 'Y-m-d', strtotime( '-1 week' ) ),
         'return' => 'ids',
      )
   );
     
   // LOOP THROUGH ORDERS AND SUM QUANTITIES PURCHASED
   $count = 0;
   foreach ( $all_orders as $all_order ) {
      $order = wc_get_order( $all_order );
      $items = $order->get_items();
      foreach ( $items as $item ) {
         $product_id = $item->get_product_id();
         if ( $product_id == $product->get_id() ) {
            $count = $count + absint( $item['qty'] ); 
         }
      }
   }
    
   if ( $count > 0 ) echo "<p>Recent sales: $count</p>";
