Change Label of date and time

No, I don't think there is any nice way of doing this.
I'll turn this into a feature request and move it to HEAD.

Is there a way of doing this for 6.x by hook form alter or something?
Right now the label is showing as [ -Year ] [ -Month ] [ -Day ] and I would like to change it to [ Year ] [ Month ] [ Day ]
Is there an example of how to do this somewhere?

Thanks!

This is crazy old, but this is how I do things like this.

function mymodule_form_alter(&$form, $form_state, $form_id) {
  switch ($form_id) {
    case 'event_node_form':  //content type of form
      $form['field_event_start_date']['#pre_render'] = array('mymodule_date_label');  //field name of the date
      break;
  }
}
/**
 *  Updates date labels on node form.
 */
function mymodule_date_label($element) {
  $element[0]['value']['#title'] = t('Start Date');
  $element[0]['value2']['#title'] = t('End Date');
  return $element;
}

Review the api reference and notice the pre_render needs to be an array. I am doing this wrong as if my module was called last and some other module was adding something here, I would reset that array. Just keep that in mind when doing yours.

Thanks, iLLin. Was having a hell of a time figuring out how to change these values with form alter.

If date field will allow to change a labels for From-To so we should decide on translation.
Once label is entered so It's a user text which does not translates with locale module

Thanks iLLin. i wanted to change it everywhere, so i added

$form['date_filter']['min']['#title'] = t('From');

to my form_alter.

I added theme functions for the date and time labels, similar to the theme functions for the year, month, day, etc labels in the select widget. Now you can override theme_date_part_label_date() and theme_date_part_label_time().

The following example shows the way to change 'Year' label of selectbox of date field.

function {module_name}_date_combo_process_alter(&$element, &$form_state, &$context) {
	
  if($element['#field_name'] == '{field_name}') {		
    $element['#pre_render'][] = '_year_labels_alter';
  }
}



function _year_labels_alter($element) {
	
  $element['value']['#pre_render'][] = '_start_year_label_alter';
  $element['value2']['#pre_render'][] = '_end_year_label_alter';
	
  return $element;
}



function _start_year_label_alter($element) {
	
  $element['year']['#title'] = t('Start Year');
	
  return $element;
}



function _end_year_label_alter($element) {
	
	$element['year']['#title'] = t('End Year');
	
	return $element;
}
