:)) rtfm, again :)) 1) http://www.php.net/manual/en/function.strtotime.php 2) http://www.gnu.org/manual/tar-1.12/html_chapter/tar_7.html 3) your second equation would return 30, not 20 ;-> 4) try this: /* untested */ function days($str_from, $str_to) { $from = strtotime(isset($str_from) ? $str_from : 'now'); $to = strtotime(isset($str_to) ? $str_to : 'now'); if ($from > $to) { $x = $from; $from = $to; $to = $x; } $rslt = $to - $from; // number in seconds return (int)($rslt / 86400); // return days (1d = 86400 secs) } Hope this helps, -- >O Ernest E.
