@bejitto101Dec 11.2008 — Well it almost looks to me like you want this to be done with JS because of that onblur but here's how you would do it with PHP. This all would be done in "action" page of the form.

I do suggest you ask in the javascript forum however.

[code=php]

$date1 = strtotime($_GET['entered_date']);
$date2 = strtotime($_GET['today_date']);

$dateDiff = $date1 - $date2;
$fullDays = floor($dateDiff/(60*60*24));
$fullHours = floor(($dateDiff-($fullDays*60*60*24))/(60*60));
$fullMinutes = floor(($dateDiff-($fullDays*60*60*24)-($fullHours*60*60))/60);
echo "Differernce is $fullDays days, $fullHours hours and $fullMinutes minutes.";
[/code]

Edit: For an example of what I think you want check here: http://javascript.internet.com/math-related/date-difference.html

@SodbusterDec 11.2008 — You can also do it like this with PHP:[code=php]function date_time_diff($start, $end, $date_only = true) // $start and $end as timestamps
{
if ($start < $end) {
list($end, $start) = array($start, $end);
}
$result = array('years' => 0, 'months' => 0, 'days' => 0);
if (!$date_only) {
$result = array_merge($result, array('hours' => 0, 'minutes' => 0, 'seconds' => 0));
}
foreach ($result as $period => $value) {
while (($start = strtotime('-1 ' . $period, $start)) >= $end) {
$result[$period]++;
}
$start = strtotime('+1 ' . $period, $start);
}
return $result;
}

$date_1 = strtotime('2005-07-31');
$date_2 = time();
$diff = date_time_diff($date_1, $date_2);
foreach ($diff as $key => $val) {
echo $val . ' ' . $key . ' ';
}

// Displays:
// 3 years 4 months 11 days[/code]

Success!
