react-calendar

What is react-calendar?

react-calendar is a flexible and customizable calendar component for React applications. It allows developers to easily integrate a calendar into their projects, providing functionalities such as date selection, navigation between months and years, and customization of calendar appearance.

What are react-calendar's main functionalities?

Basic Calendar

This is the most basic usage of the react-calendar package, rendering a simple calendar component.

<Calendar />

Date Selection

Allows users to select a date. The selected date is managed via state in the parent component.

<Calendar onChange={setDate} value={date} />

Range Selection

Enables users to select a range of dates. The selected range is managed via state in the parent component.

<Calendar selectRange={true} onChange={setDateRange} value={dateRange} />

Custom Tile Content

Allows customization of the content of each tile in the calendar. In this example, a 'Special' label is added to Sundays.

<Calendar tileContent={({ date, view }) => view === 'month' && date.getDay() === 0 ? <p>Special</p> : null} />

Navigation Between Views

Allows setting the default view of the calendar to 'year', 'month', 'decade', or 'century'.

<Calendar defaultView='year' />

react-datepicker is a popular date picker component for React. It offers a wide range of features including date and time selection, range selection, and localization support. Compared to react-calendar, react-datepicker provides more advanced date and time picking functionalities but may require more configuration for basic calendar views.

react-big-calendar

react-big-calendar is a powerful calendar component for React that supports events, drag-and-drop, and customizable views. It is more feature-rich compared to react-calendar, making it suitable for applications that require complex scheduling and event management.

fullcalendar-react

fullcalendar-react is a React wrapper for FullCalendar, a highly customizable and feature-rich calendar library. It supports a wide range of views, event management, and customization options. It is more comprehensive than react-calendar, making it ideal for applications that need extensive calendar functionalities.

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
• v2.x

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:

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 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:

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