Min book kalender

Burde dette ikke tegne en kalender?:


<font style="color: #FFFFFF" face="Verdana" size="2">
<table bgcolor="#000000" cellspacing="0" cellpadding="0" align="center">
<tr><td width="30" style=\"color:#FFFFFF\">S</td><td width="30" style=\"color:#FFFFFF\">M</td><td width="30" style=\"color:#FFFFFF\">T</td><td width="30" style=\"color:#FFFFFF\">O</td><td width="30" style=\"color:#FFFFFF\">T</td><td width="30" style=\"color:#FFFFFF\">F</td><td width="30" style=\"color:#FFFFFF\">L</td></tr>
<?
$month = (isset($_GET[month])) ? $_GET[month] : date("m");
$year = (isset($_GET[year])) ? $_GET[year] : date("Y");
$day = 1;
for ($y=1; $y < 5; $y++) {
    echo "<tr>";
    for ($i=0;$i<7;$i++) {
        if ($y == 1) {
            if (date("z",mktime(0,0,0,$day,$month,$year)) != $i) {
                echo "<td style=\"color:#FFFFFF\">-</td>";
            } else {
                echo "<td style=\"color:#FFFFFF\"><a href=\"index.php?p=book.php&month=$month&year=$year&day=$day\">$day</td>";
            }
            $day++;
            } elseif ($y == 5) {
                if ($day < date("t",mktime(0,0,0,1,$month, $year))) {
                    echo "<td style=\"color:#FFFFFF\">-</td>";
                }else{
                    echo "<td style=\"color:#FFFFFF\"><a href=\"index.php?p=book.php?month=$month&year=$year&day=$day\">";
                }
                $day++;
            }
        echo "</tr>";
    }
$day = 1;
}
?>
