Calendar table disappears (timezone problems)

My calendar table doesn't appear when I add an event for the last day of the month. The weird thing is that if I have any other events scheduled in the same month, the calendar appears, but the last day's event doesn't show up in the calendar. So, for instance, I have an event scheduled for Nov. 30 and another one scheduled for Nov. 25, but the Nov. 30 event doesn't show up. If I delete the Nov. 25 event, the calendar table disappears altogether. I'm using a cck type with a date field for the events. Any ideas?

Here's the view:

$view = new stdClass();
  $view->name = 'event_calendar';
  $view->description = 'Calendar view of any date field, add a date field to the view to use it.';
  $view->access = array (

  $view->page = TRUE;
  $view->page_title = 'Calendar';
  $view->page_header = '';
  $view->page_header_format = '1';
  $view->page_footer = '';
  $view->page_footer_format = '1';
  $view->page_empty = '';
  $view->page_empty_format = '1';
  $view->page_type = 'calendar';
  $view->url = 'calendar';
  $view->use_pager = FALSE;

  $view->block_empty_format = '1';
  $view->block_type = 'calendar';
  $view->nodes_per_block = '999';
  $view->block_more = TRUE;
  $view->block_use_page_header = FALSE;
  $view->block_use_page_footer = FALSE;
  $view->block_use_page_empty = FALSE;
  $view->sort = array (
    array (
      'tablename' => 'node_data_field_event_date',
      'field' => 'field_event_date_value',

    array (

  );

      'value' => 'now',
    ),
  );
  $view->exposed_filter = array (
  );
  $view->requires = array(node_data_field_event_date, node);
  $views[$view->name] = $view;

Here's the cck type:

$content[type]  = array (
