My input date, if i select German as language, is \"20.03.2013\". I get an validation

Answer 1

Try overwriting the default date validator:

// Replace dots so jq validator can understand what's going on
$(function () {
    $.validator.addMethod(
    "date",
    function (value, element) {
        var s = value;
        s = value.replace(/\./g, '/');

        // Chrome requires tolocaledatestring conversion, otherwise just use the slashed format
        var d = new Date();
        return this.optional(element) || !/Invalid|NaN/.test(new Date(d.toLocaleDateString(value))) || !/Invalid|NaN/.test(new Date(s));
    },
    ""
    );
});

$.validator.unobtrusive.parse();
