jQuery Date Validation (YYYY-MM-DD)

I need to validate a date using this script in the format of YYYY-MM-DD, but I can't seem to get it working perfectly. With the regular expression I'm using, it allows for users to enter 10 numbers without dashes, instead of 8 with dashes in the correct places. Is there a way to modify my script to fix this?

jQuery.validator.addMethod("date", function(date, element) {
                return this.optional(element) || date.match(/^[-0-9]{10}$/);
            }, "Please specify a valid date");

This would validate the exact format with dashes in the correct place.

/^(\d{4})-(\d\d)-(\d\d)$/

Fuller validation to ensure sensible year/month/day values could be

/^(19|20)\d\d-(0\d|1[012])-(0\d|1\d|2\d|3[01])$/

You have a wrong regex.

You can use this one instead :

^\d{4}-((0\d)|(1[012]))-(([012]\d)|3[01])$

So it would be :

return this.optional(element) || date.match(/^\d{4}-((0\d)|(1[012]))-(([012]\d)|3[01])$/);
