Answer 1

Look at http://www.intelligrape.com/blog/2010/03/31/client-side-date-validation-using-jquery-plugins/

jQuery.validator.addMethod("customDateValidator", function(value, element) {
        // parseDate throws exception if the value is invalid
        try{jQuery.datepicker.parseDate( 'm/dd/yy', value);return true;}
        catch(e){return false;}
    },
    "Please enter a valid date"
);

Answer 2

Create a custom validator:

jQuery.validator.addMethod("mydate", function(value, element) { 
  return this.optional(element) || /^\d\d?-\w\w\w-\d\d\d\d/.test(value); 
}, "Please specify the date in DD-MMM-YYYY format");
