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:
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.
My locale isn't supported! What can I do?
If your locale isn't supported, you can use 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:
1import { useState } from 'react'; 2import Calendar from 'react-calendar'; 3 4type ValuePiece = Date | null; 5 6type Value = ValuePiece | [ValuePiece, ValuePiece]; 7 8function MyApp() { 9 const [value, onChange] = useState<Value>(new Date()); 10 11 return ( 12 <div> 13 <Calendar onChange={onChange} value={value} /> 14 </div> 15 ); 16}
Check the sample directory in this repository for a full working example. For more examples and more advanced use cases, check Recipes in 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:
1import 'react-calendar/dist/Calendar.css';
