Use the source, Luke.
http://api.cakephp.org/view_source/validation/#line-389

$regex['ymd'] =
'%^(?:(?:(?:(?:(?:1[6-9]|[2-9]\\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(\\/|-|\\.|\\x20)(?:0?2\\1(?:29)))|(?:(?:(?:1[6-9]|[2-9]\\d)?\\d{2})(\\/|-|\\.|\\x20)(?:(?:(?:0?[13578]|1[02])\\2(?:31))|(?:(?:0?[1,3-9]|1[0-2])\\2(29|30))|(?:(?:0?[1-9])|(?:1[0-2]))\\2(?:0?[1-9]|1\\d|2[0-8]))))$%';

Note the "1[6-9]|[2-9]". I believe that's saying, "(1 AND 6-9) OR (1
AND 2-9), which wouldn't be desirable. Although, if it's supposed to
be, "1 AND (6-9 OR 2-9) it still doesn't make much sense.

Or maybe it's the "16|[2468][048]|[3579][26])00" part. I'm going
cross-eyed looking at this.

I figured the trouble would be due to something like this. For routes,
one can use the built-in $Year, which is a regexp defined as
"[12][0-9]{3}". So, nothing before year 1000, in that case. I think it
should be "[12]?[0-9]{3}". But, then that would limit you only to
dates after 100AD, of course.
