Is there a way to display only the current month calendar?

Basically, all I did was copy and edit og_calendar_page to get the current month. Take a look. If it looks ok, then I'll create a patch. Thanks.

/**
 * Modification - limited to current month ONLY
 *
 * views either all group events or a specific group's calendar
 */
function og_calendar_page_current($gid = NULL) {
  if ($gid) {
    $group = node_load($gid);
    $nodes = array();
    og_set_group_context($group);
    $bc[] = l(t('Home'), '');
    $bc[] = l(t('Groups'), 'og');
    $bc[] = l($group->title, "node/$gid");
    drupal_set_breadcrumb($bc);

    // Maintains group theme for og calendar view
  	og_set_theme($gid);

	// Basically, modified og_calendar_page and added code to get the parameters for the current month:

		// Get today's date in YYYY-MM-DD format.  This format is easiest for me to work with.
			$todays_date = date("Y-m-d", time()); 
		// Get todays year, month and day values
			list($year, $month, $day) = split("-", $todays_date);
		// The year to use for end date year;
			$next_year = $year;
		// The month to use for end date month;	
			$next_month = $month+1;
		// Check to make sure we update end date to next year if current month is 12	
			if ($next_month == 13) {
    	 		$next_month = 1;
      			$next_year = $year + 1;
			}
		// Make sure we put leading zero in if month < 10
			if ($next_month < 10) $next_month = '0' . $next_month;
		// Start date is the first of this month
			$start_date = $year . "-" . $month . "-01";
		// End date is the first of next month
			$end_date = $next_year . "-" . $next_month . "-01";
		// Now, we create the unix format start and end dates
  			$parts = explode("-",$start_date);
		  	$start_date_unix = mktime(12,0,0,$parts[1],$parts[2],$parts[0]);
  			$parts = explode("-",$end_date);
		  	$end_date_unix = mktime(12,0,0,$parts[1],$parts[2],$parts[0]);

    // View only events from this group limited by above timeframe (start date / end date)
    $sql = "SELECT e.nid, e.event_start, e.event_end FROM {event} e INNER JOIN {node} n ON n.nid = e.nid";
    $sql = db_rewrite_sql($sql, 'n', 'nid', array('og_nid' => $gid));
    $result = db_query($sql, $gid);
    while ($nid = db_fetch_object($result)) {
      $event = node_load($nid->nid);
	  // We need to get the event start date so we know how to set the timeframe;
		  $event_start = $nid->event_start;
		  $event_end = $nid->event_end;
      // Get only event nodes that fall within the timeframe
      	if ($event_start >= $start_date_unix && $event_start < $end_date_unix) {
      		if (isset($event->nid)) {
        		$nodes[$event->nid] = $event;
		      }
		  }
    	}
    if (count($nodes)) {
      $output = event_get_calendar('month', $nodes, 'og_calendar', t('@name calendar', array('@name' => $group->title)));
      $output .= theme('event_ical_link', 'event/ical/'. $node->filter);

      // Add RSS feed and icon to events page
      drupal_add_link(array(
        'rel' => 'alternate',
        'type' => 'application/rss+xml',
        'title' => t('RSS'),
        'href' => url('event/feed', NULL, NULL, TRUE)
      ));
      $output .= theme('feed_icon', url('event/feed'));

      return $output;
    }
    else {
      return t('No (visible) events for the @name group were found!', array('@name' => $group->title));
    }
  }
  else {
    // Redirect to the main event page
    drupal_goto('event');
  }
}

Here is the og_calendar patch with allows viewing of single month as well as previous/next month paging. It works for me. Please let me know what you think.

You call it like this: /og_calendar_curr/

That's

/og_calendar_curr/$gid
