Compare 2 date in cake3

I've been tried with:

        $validator ->add('end_date', [

            'valid'=> ['rule' => 'date'] ,

            'compare' =>['rule' => ['comparison', '>' ,'start_date']]

             ]

            );

but doesn't work;

how to validate start_date and end_date ( end must be greater than start_date) ?
