Should there be a minus instead of a plus in that query?
Why not
$date = date('Y-m-d', strtotime('-14 days'));
$sql = "select actTitle, actStartDate from smmbc_events where " .
"actStartDate >= '$date' LIMIT 5 ";
Select the date as it is and format on display with
$displayDate = date ('M jS', strtotime($row['actStartDate']));
