title: DateField summary: How to format and use the DateField class. # DateField This `FormField` subclass lets you display an editable date, in a single text input field. It implements the [HTML5 input date type](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date) (with `type=date`). In supported browsers, this will cause a localised date picker to appear for users. HTML5 date fields present and save ISO 8601 date formats (`y-MM-dd`), since the browser takes care of converting to/from a localised presentation. Browsers without support receive an `` based polyfill. The following example will add a simple DateField to your Page, allowing you to enter a date manually. **mysite/code/Page.php** ```php class Page extends SiteTree { private static $db = [ 'MyDate' => 'Date', ]; public function getCMSFields() { $fields = parent::getCMSFields(); $fields->addFieldToTab( 'Root.Main', DateField::create('MyDate', 'Enter a date') ); return $fields; } } ``` ## Custom Date Format A custom date format for a [DateField](api:SilverStripe\Forms\DateField) can be provided through `setDateFormat`. This is only necessary if you want to opt-out of the built-in browser localisation via `type=date`. ```php // will display a date in the following format: 31/06/2012 DateField::create('MyDate') ->setHTML5(false) ->setDateFormat('dd/MM/yyyy'); ```
