Move the date meta in posts

How can I move the date meta of each post (article / excerpt / post) at the bottom of these ? Currently it’s on top of each post above its title.
I’ve looked into single.php where there is :

 <?php while ( have_posts() ) : the_post();
 do_action( 'storefront_single_post_before' );
 get_template_part( 'content', 'single' );
 do_action( 'storefront_single_post_after' );
 endwhile; // End of the loop. ?>

So I guess there is a way to move storefront_single_post_before between content and storefront_single_post_after

but how ?

(css class .hentry .entry-header .posted-on )
