		$end	= new DateTime(date('Y-m-t', strtotime($end_date)));
        $end	= $end->modify( '+1 day' );

        $result		= array();
		$daterange	= new DatePeriod($begin, new DateInterval('P1M'), $end);
		foreach($daterange as $date)
		{
			$result[] = $date->format($format);
		}
        return $result;
