Quick FAQs on input[type=date] in Google Chrome

  • This article is written by a Chrome software engineer Kent Tamura.

As you might have already noticed, Google Chrome supports a datepicker since Chrome 20. Just by setting the type attribute of the input element to date, the user can click the arrow button and Chrome will pop up a nice calendar widget.

As we have received a lot of feedback from developers, we'd like to clarify a few things about how to get the best out of using the date picker in this article.

How does locale affect the date format of the input value?

Users can type a date value into the text field of an input[type=date] with the date format shown in the box as gray text. This format is obtained from the operating system's setting.

Date formats screen

Web authors have no way to change the date format because there currently is no standards to specify the format.

How is the input value represented when sending to a server?

The date value interpreted from input[type=date] in the HTTP Request such as GET / POST will be formatted as yyyy-mm-dd.

What kind of format does the input value return?

The input.value always returns as yyyy-mm-dd regardless of the presentation format.

What kind of format does the input value accept?

When setting the input.value programmatically, the value accepts only yyyy-mm-dd style regardless of the presentation format for both the initial value and the JavaScript injected value.

How do I change the appearance of the date picker?

You cannot currently style the appearance of the date picker. In WebKit, we have previously provided ways to style form controls with the -webkit-appearance CSS property or the ::-webkit-foo pseudo class selector. However the calendar popup does not provide such ways in WebKit because it is separate from the document, like a popup menu for <select>, and there is not currently a standard for how to control styling on its sub-elements.

How do I avoid conflicts between the jQuery Datepicker and the native date picker?

If you have tried jQuery Datepicker on input[type=date] in Google Chrome, you might have noticed overlapping calendars of both the jQuery UI and the native calendar popup. If you'd like to apply jQuery Datepicker on all platforms, use input[type=text] instead of input[type=date]. Not only Google Chrome but also iOS Safari, the BlackBerry browser, and Opera have their own UI for input[type=date], and there is currently no way to achieve a unified UI on all platforms using input[type=date]. If you'd like to apply jQuery Datepicker only on platforms without input[type=date] support, you may use Modernizr, or the following code:

var isDateInputSupported = function(){
var elem = document.createElement('input');
elem.value = 'foo';
return (elem.type == 'date' && elem.value != 'foo');

if (!isDateInputSupported())  // or.. !Modernizr.inputtypes.date
