How to correctly display the name of the month in the Calendar module?

Question

Drupal

Drupal 7, Calendar 3.5 module, Date 2.8 module.
Year tab. In addition to the name of the month, the name of the first day of the week of the month is also displayed:
Thursday, January 1 instead of January
Sunday, February 1 instead of February
Sunday, March 1 instead of March
Has anyone come across? How to fight?

Answer 1

came across just a few days ago.
I don’t remember where I found it, I copy it from my topic.
add the following code to the template.php file (instead of mytheme - the name of your theme):

function MYYTHEME_date_nav_title($params) {
  $granularity = $params['granularity'];
  $view = $params['view'];
  $date_info = $view->date_info;
  $link = !empty($params['link']) ? $params['link'] : FALSE;
  $format = !empty($params['format']) ? $params['format'] : NULL;
  switch ($granularity) {
    case 'year':
      $title = $date_info->year;
      $date_arg = $date_info->year;
      break;
    case 'month':
      $format = !empty($format) ? $format : (empty($date_info->mini) ? 'F Y' : 'F Y');
      $title = date_format_date($date_info->min_date, 'custom', $format);
      $date_arg = $date_info->year .'-'. date_pad($date_info->month);
      break;
    case 'day':
      $format = !empty($format) ? $format : (empty($date_info->mini) ? 'l, F j Y' : 'l, F j');
      $title = date_format_date($date_info->min_date, 'custom', $format);
      $date_arg = $date_info->year .'-'. date_pad($date_info->month) .'-'. date_pad($date_info->day);
      break;
    case 'week':
        $format = !empty($format) ? $format : (empty($date_info->mini) ? 'F j Y' : 'F j');
      $title = t('Week of @date', array('@date' => date_format_date($date_info->min_date, 'custom', $format)));
        $date_arg = $date_info->year .'-W'. date_pad($date_info->week);
        break;
  }
  if (!empty($date_info->mini) || $link) {
      // Month navigation titles are used as links in the mini view.
    $attributes = array('title' => t('View full page month'));
      $url = date_pager_url($view, $granularity, $date_arg, TRUE);
    return l($title, $url, array('attributes' => $attributes));
  }
  else {
    return $title;
  }  
}
