You can easily deal with the exception by catching it, this will fix the error in the sense that you don’t need to bother about that error any longer:

try {
    $newday = $a['dayz'];
    $endmonth = $a['monthz'];
    $newyear = $a['yearz'];
    $date = new DateTime("$newyear-$endmonth-$newday");
    $date->modify('+8 day');
    $year = $date->format('Y');
    $month = $date->format('m');
    $day = $date->format('d');
} catch(Exception $e) {
    # do nothing
}

At least at some point you need to do error handling. Exceptions require you to do that, DateTime throws exceptions.
