The typical 'from' 'to' datefields are not quite good for usability. With the following snippet you can change the labels in a drupal 8 website..
/**
* @param $form
* @param FormStateInterface $form_state
* @param $form_id
*/
function MYMODULE_form_alter(&$form, FormStateInterface $form_state, $form_id) {
if($form_id == 'views_exposed_form' && $form['#id'] == 'views-exposed-form-VIEW_ID') {
$form['date']['min']['#title'] = 'Date between';
$form['date']['max']['#title'] = 'and';
}
}
