How to remove the default date format option added by date module ?
How to Change the Title, Change the description ("E.g., 29/07/2016") of the date widget ?

For thah you must use an additional process.

1. Create a custom module (Example : Here we use mymodule)

2. in the mymodule.module, add the hook hook_alter_element_info_alter and create a function '_mymodule_date_popup_process_alter'


 * implements hook_element_info_alter()
function mymodule_alter_element_info_alter(&$type) {
  if (isset($type['date_popup'])) {
    $type['date_popup']['#process'][] = '_mymodule_date_popup_process_alter';
function _mymodule_date_popup_process_alter(&$element, &$form_state, $context) {
  if ($element['#name'] == 'node_changed') {
    $element['date']['#title'] = "The Date is";
  return $element;
