jQuery.validator.addMethod("greaterThan", function(value, element, params) {
    if (this.optional(element)) {  // "required" not in force and field is empty
        return true;
    } else {  // otherwise, use your rule
        if (!/Invalid|NaN/.test(new Date(value))) {
            return new Date(value) > new Date($(params).val());
        }
        return isNaN(value) && isNaN($(params).val()) || (Number(value) > Number($(params).val()));
    }
},'Must be greater than {0}.');
