The Unix epoch which mktime uses starts on January 1, 1970. Wikipedia Article

Someone born in 1970 would be 38 today.

You will need to some modifications to that script to get accurate ages before that date.

You could do something like the following:

php Code:

<?php
function calculate_age ($month, $day, $year) { 
    $year_diff = date("Y") - ($year);
    $month_diff = date("m") - ($month);
    $day_diff = date("d") - ($day);
    
    if ($month_diff < 0) {
        $year_diff--;
    }
    elseif ($month_diff == 0 && $day_diff < 0) {
        $year_diff--;
    }

    return $year_diff;
}
?>
