for example use:
_e(‘the things to print’)
or if woocommerce is being used its possible to use this way:
_e(‘the things to print’, ‘woocommerce’)
add_filter( 'get_the_date', function($the_date, $d, $post){
$date = new DateTime( $post->post_date );
echo _e($date->format('j F, Y')); // change formatting as needed
}, 10, 3 );
