    The W3 validator says placeholder attributes are not valid on date inputs. Validating this HTML:

    <!doctype html>
<title>date placeholder test</title>
<input type="date"  placeholder="enter a date">

    Gives the error: “Attribute placeholder not allowed on element input at this point.” … and says you can use the attribute “placeholder when type is text, search, url, tel, e-mail, password, or number“.

    Also, Chrome doesn’t show the placeholder for date inputs, even though it thinks the attribute exists in JS (this is roughly how Modernizr checks for attributes):

    var test = document.createElement(element);
test.type = 'date';
alert('placeholder' in test);
