Why another date picker? The problem is that most of existing solutions do not follow standards regarding to value property format, that should have “a valid full-date as defined in [RFC 3339]”. In other words representation of date can vary, but the string value should have yyyy-MM-dd format. It helps to work with such values consistently regarding on the current language.

Then append the following scripts to your page:

<script src="node_modules/better-dateinput-polyfill/dist/better-dateinput-polyfill.js"></script>

Forcing the polyfill

Sometimes it's useful to override browser implemetation with the consistent control implemented by the polyfill. To suppress feature detection you can add <meta name="dateinput-polyfill-media"> into your document <head>. Value of content attribute is a media query where polyfill will be applied:

<!-- force polyfill everywhere -->
<meta name="dateinput-polyfill-media" content="screen">
<!-- force polyfill only on mobile devices in portrait mode-->
<meta name="dateinput-polyfill-media" content="screen and (orientation: portrait)">

Change default date presentation format

When no spicified polyfill uses browser settings to format displayed date. You can override date presentation globally with <meta name="dateinput-polyfill-format"> via content attribute or directly on a HTML element with data-format attribute. Value should be options for the Date#toLocaleString call as a stringified JSON object:

<html>
<head>
    <!-- Override default date presentation format -->
    <meta name="dateinput-polyfill-format" content='{"month":"long","year":"numeric","day":"numeric"}'>
</head>
<body>
    <!-- Override date presentation format on a particular element -->
    <input type="date" data-format='{"month":"short","year":"numeric","day":"numeric"}'>
</body>
</html>
