Localizing jquery validation with asp.net mvc 3

Question

I am using Asp.Net Mvc3 and the unobtrusive jquery validation. I'd like to have my dates validation localized, I mean, jquery is validating my date as being MM/dd/yyyy but I would like it to be dd/MM/yyyy.

I'm trying to use the jQuery Globalize plugin (http://github.com/jquery/globalize). I added references to the scripts globalize.js and globalize.culture.pt-BR.js and when my page loads I'm running the follwing script:

(function() {
  $(function() {
    $.datepicker.setDefaults($.datepicker.regional['pt-BR']);
    Globalize.culture("pt-BR");
  });
}).call(this);

The jQuery UI plugin works as charm, but the validation doesn't. What else am I missing?

Edit:

Using the links in the answer below I solved the problem using the Globalize plugin:

Of course, I had to add a reference to the Globalize plugin in the page and also a reference to the culture that I wanted to use (all available on the plugin's site). After that is just a small piece of JavaScript code.

Globalize.culture("pt-BR");
$.validator.methods.date = function(value, element) {
    return this.optional(element) || Globalize.parseDate(value);
};

I've been doing similar myself recently. I started by following the advice in Scott Hanselman's blog on this topic - you can read about this here:

I had to make some changes to use Globalize instead of jQuery Global (now jQuery Global is dead). I wrote this up in the following blog post in case that's helpful:

My blog post features a link to this script jquery.validate.globalize.js which forces jQuery Validate to use Globalize for number / date / range parsing. The date part of this is the part that should probably solve your issue:

https://raw.github.com/gist/3651751/68cbccd0fdd4725a8d6fd1b5568bb33d27fb1eff/jquery.validate.globalize.js

/// <reference path="jquery-1.7.2.js" />
/// <reference path="jquery.validate.js" />
/// <reference path="globalize.js" />

/*!
* Monkey patch for jquery.validate.js to make use of Globalize.js number and date parsing
*/

$(document).ready(function () {

    var currentCulture = $("meta[name='accept-language']").prop("content");

    // Set Globalize to the current culture driven by the meta tag (if any)
    if (currentCulture) {
        Globalize.culture(currentCulture);
    }

    //Tell the validator that we want numbers parsed using Globalize.js
    $.validator.methods.number = function (value, element) {    
        if (Globalize.parseFloat(value)) {
            return true;
        }
        return false;
    }

    //Tell the validator that we want dates parsed using Globalize.js
    $.validator.methods.date = function (value, element) {
        if (Globalize.parseDate(value)) {
            return true;
        }
        return false;
    }

    //Fix the range to use globalized methods
    jQuery.extend(jQuery.validator.methods, {
        range: function (value, element, param) {
            //Use the Globalization plugin to parse the value
            var val = Globalize.parseFloat(value);
            return this.optional(element) || (val >= param[0] && val <= param[1]);
        }
    });

});
