	$w = array(date('w', $start), date('w', $end));
	$x = floor(($end-$start)/604800);
	$sum = 0;
	for ($day = 0;$day < 7;++$day) {
		if ($days & pow(2, $day)) {
			$sum += $x + ($w[0] > $w[1]?$w[0] <= $day || $day <= $w[1] : $w[0] <= $day && $day <= $w[1]);
		}
	}
	return $sum;
}

function getWeeklyDayNumbers($startDate, $endDate) {
	$weekdays = array('monday' => 0, 'tuesday' => 0, 'wednesday' => 0, 'thursday' => 0, 'friday' => 0, 'saturday' => 0, 'sunday' => 0);
	$weekdays['monday'] += number_of_days(0x02, $startDate, $endDate); // MONDAY
	$weekdays['tuesday'] += number_of_days(0x04, $startDate, $endDate); // TUESDAY
	$weekdays['wednesday'] += number_of_days(0x08, $startDate, $endDate); // WEDNESDAY
