echo build_calendar(11, 2013);

Replace line 28 with this to highlight the current date

    // Is this today?
    if(date('Y-m-d') == $date) {
        $calendar .= "<td class='day success' rel='$date'><b>$currentDay</b></td>";
    } else {
        $calendar .= "<td class='day' rel='$date'>$currentDay</td>";
    }
