I have custom date format that looks like:
M jS Y g:i a (Feb 23rd 2016 3:32 pm )
It's really hard to write regex to that format like this, how I can detect that date have that format ?

If you don't need necessarily a regex, just use the date_create_from_format function. It returns FALSE if it's unable to parse the string, so you can check on its return value.
$dateObject = date_create_from_format("M jS Y g:i a", "Feb 23rd 2016 3:32 pm");
if ($dateObject === false) {
// string is in a wrong format
}

The regular expressions are not the best solution in your case. PHP already provides good support for date/time parsing from strings.
Use DateTime::createFromFormat() to parse your string. It returns a valid DateTime object when the parsing succeeds or FALSE when the parsing fails:
$date = DateTime::createFromFormat(
'M jS Y g:i a',
'Feb 23rd 2016 3:32 pm',
new DateTimeZone('UTC') // put your timezone here
);
print_r($date);
It displays:
DateTime Object
(
[date] => 2016-02-23 15:32:00.000000
[timezone_type] => 3
[timezone] => UTC
)
