## Before you continue

react-calendar is under constant development. This documentation is written for react-calendar 4.x branch. If you want to see documentation for other versions of react-calendar, use dropdown on top of GitHub page to switch to an appropriate tag. Here are quick links to the newest docs from each branch:

- [v3.x](https://github.com/wojtekmaj/react-calendar/blob/v3.x/README.md)
- [v2.x](https://github.com/wojtekmaj/react-calendar/blob/v2.x/README.md)

## Getting started

### Compatibility

Your project needs to use React 16.8 or later.

react-calendar uses modern web technologies. That's why it's so fast, lightweight and easy to style. This, however, comes at a cost of [supporting only modern browsers](https://caniuse.com/#feat=internationalization).

#### Legacy browsers

If you need to support legacy browsers like Internet Explorer 10, you will need to use [Intl.js](https://github.com/andyearnshaw/Intl.js/) or another Intl polyfill along with react-calendar.

#### My locale isn't supported! What can I do?

If your locale isn't supported, you can use [Intl.js](https://github.com/andyearnshaw/Intl.js/) or another Intl polyfill along with react-calendar.

### Installation

Add react-calendar to your project by executing `npm install react-calendar` or `yarn add react-calendar`.

### Usage

Here's an example of basic usage:

```tsx
import { useState } from 'react';
import Calendar from 'react-calendar';

type ValuePiece = Date | null;

type Value = ValuePiece | [ValuePiece, ValuePiece];

function MyApp() {
  const [value, onChange] = useState<Value>(new Date());

  return (
    <div>
      <Calendar onChange={onChange} value={value} />
    </div>
  );
}
```

Check the [sample directory](https://github.com/wojtekmaj/react-calendar/tree/main/sample) in this repository for a full working example. For more examples and more advanced use cases, check [Recipes](https://github.com/wojtekmaj/react-calendar/wiki/Recipes) in [react-calendar Wiki](https://github.com/wojtekmaj/react-calendar/wiki).

### Custom styling

If you want to use default react-calendar styling to build upon it, you can import react-calendar's styles by using:

```ts
import 'react-calendar/dist/Calendar.css';
```

## User guide

### Calendar

Displays a complete, interactive calendar.
