HTML-5 date field shows as "mm/dd/yyyy" in Chrome, even when valid date is set

I was having the same problem, with a value like 2016-08-8, then I solved adding a zero to have two digits days, and it works. Tested in chrome, firefox, and Edge

today:function(){
   var today = new Date();
   var d = (today.getDate() < 10 ? '0' : '' )+ today.getDate();
   var m = ((today.getMonth() + 1) < 10 ? '0' :'') + (today.getMonth() + 1);
   var y = today.getFullYear();
   var x = String(y+"-"+m+"-"+d); 
   return x;
}

In chrome to set the value you need to do YYYY-MM-DD i guess because this worked : http://jsfiddle.net/HudMe/6/

So to make it work you need to set the date as 2012-10-01

Had the same problem. A colleague solved this with jQuery.Globalize.

<script src="/Scripts/jquery.validate.js" type="text/javascript"></script>
<script src="/Scripts/jquery.globalize/globalize.js" type="text/javascript"></script>
<script src="/Scripts/jquery.globalize/cultures/globalize.culture.nl.js"></script>
<script type="text/javascript">
    var lang = 'nl';

    $(function () {
        Globalize.culture(lang);
    });

    // fixing a weird validation issue with dates (nl date notation) and Google Chrome
    $.validator.methods.date = function(value, element) {
        var d = Globalize.parseDate(value);
        return this.optional(element) || !/Invalid|NaN/.test(d);
    };
</script>

I am using jQuery Datepicker for selecting the date.
