jQuery/JavaScript: Is it a date? (Validate whether is a date)

I have datepicker, but I could not find a way to validate if the user's entry is a date or not AND if it follows the required format (format: yyyy-mm-dd)

This is my datepicker:

$(input[name='date']).datepicker({ dateFormat: 'yy-mm-dd', changeMonth: true, changeYear: true, numberOfMonths: 3, showButtonPanel: true});

I looked on this solution, How to validate datepicker to forbid/reject certain dates?. It looks simple enough, but it only checks whether it's a weekend. It does not checks it the user entered a date, a random number or a typo (1231....30-30-2011...30/30/2011...212-565-565...etc.).

Please fiddle with my fiddle: http://jsfiddle.net/MDa4A/

Additional info (11-10-2011):

(Try these jsFiddles and type 0-0-0 or 0/0/0)

I used your answers to come up with a solution. It works when I use the format yy-mm-dd: http://jsfiddle.net/LyEvQ/

BUT it is totally useless when I use a different format (Ej.: mm/dd/yy): http://jsfiddle.net/LyEvQ/1/

I need both to work. Can you please help

Something like this should work:

jQuery.validator.addMethod(customDateValidator,

    function(value, element) {

        try { jQuery.datepicker.parseDate(mm/dd/yyyy, value); return true; }

        catch(e) { 

            return false;

        }

    },

    Please enter a valid date

);



$(input[name='date']).rules(add, { customDateValidator:true });
