&lt;/div&gt;
}
&lt;script&gt;

angular.module("myApp", ["kendo.directives"]).controller("myCtrl", function ($scope) {

});
&lt;/script&gt;
</code></pre>

<p>and asp.net mvc controller</p>

<pre><code>[HttpPost]
public ActionResult Add(DateTime? Birthday = null)
{
    DateTime? temp = Birthday;
    return View();
}
</code></pre>

<p>If i set server datetime by en-US is Birthday always null, but set by vi-VN then OK. How can i take Birthday value and don't change server datetime and keep format for datepicker ?</p>
