# Input Date
`lion-input-date` component is based on the generic text input field. Its purpose is to provide a way for users to fill in a date.
```js script
import { html } from 'lit-html';
import { MinDate, MinMaxDate, MaxDate } from '@lion/form-core';
import { loadDefaultFeedbackMessages } from '@lion/validate-messages';
import { formatDate } from '@lion/localize';
import './lion-input-date.js';
export default {
title: 'Forms/Input Date',
};
loadDefaultFeedbackMessages();
```
```js preview-story
export const main = () => html` <lion-input-date label="Date"></lion-input-date> `;
```
## Features
- Based on [lion-input](?path=/docs/forms-input--main#input)
- Makes use of [formatDate](?path=/docs/localize-dates--formatting#date-localization) for formatting and parsing.
- Option to override locale to change the formatting and parsing
- Default label in different languages
- Can make use of date specific [validators](?path=/docs/forms-validation-overview--main#validate) with corresponding error messages in different languages
- IsDate (default)
- MinDate
- MaxDate
- MinMaxDate
