react-big-calendar

An events calendar component built for React and designed for modern browsers (read: not IE) and uses flexbox over the classic tables-caption approach.

DEMO and Docs

Inspired by Full Calendar.

yarn add react-big-calendar or npm install --save react-big-calendar

Include react-big-calendar/lib/css/react-big-calendar.css for styles, and make sure your calendar's container element has a height, or the calendar won't be visible. To provide your own custom styling, see the Custom Styling topic.

Localization and Date Formatting

react-big-calendar includes four options for handling the date formatting and culture localization, depending on your preference of DateTime libraries. You can use either the Moment.js, Globalize.js, date-fns, Day.js localizers.

Regardless of your choice, you must choose a localizer to use this library:

Moment.js

import { Calendar, momentLocalizer } from 'react-big-calendar'
import moment from 'moment'

const localizer = momentLocalizer(moment)

const MyCalendar = (props) => (
  <div>
    <Calendar
      localizer={localizer}
      events={myEventsList}
      startAccessor="start"
      endAccessor="end"
      style={{ height: 500 }}
    />
  </div>
)

Globalize.js v0.1.1

import { Calendar, globalizeLocalizer } from 'react-big-calendar'
import globalize from 'globalize'

const localizer = globalizeLocalizer(globalize)

const MyCalendar = (props) => (
  <div>
    <Calendar
      localizer={localizer}
      events={myEventsList}
      startAccessor="start"
      endAccessor="end"
      style={{ height: 500 }}
    />
  </div>
)

date-fns v2

import { Calendar, dateFnsLocalizer } from 'react-big-calendar'
import format from 'date-fns/format'
import parse from 'date-fns/parse'
import startOfWeek from 'date-fns/startOfWeek'
import getDay from 'date-fns/getDay'
import enUS from 'date-fns/locale/en-US'

const locales = {
  'en-US': enUS,
}

const localizer = dateFnsLocalizer({
  format,
  parse,
  startOfWeek,
  getDay,
  locales,
})

const MyCalendar = (props) => (
  <div>
    <Calendar
      localizer={localizer}
      events={myEventsList}
      startAccessor="start"
      endAccessor="end"
      style={{ height: 500 }}
    />
  </div>
)

Day.js

Note that the dayjsLocalizer extends Day.js with the following plugins:

• IsBetween
• IsSameOrAfter
• IsSameOrBefore
• LocaleData
• LocalizedFormat
• MinMax
• UTC

import { Calendar, dayjsLocalizer } from 'react-big-calendar'
import dayjs from 'dayjs'

const localizer = dayjsLocalizer(dayjs)

const MyCalendar = (props) => (
  <div>
    <Calendar
      localizer={localizer}
      events={myEventsList}
      startAccessor="start"
      endAccessor="end"
      style={{ height: 500 }}
    />
  </div>
)

Custom Styling

Out of the box, you can include the compiled CSS files and be up and running. But, sometimes, you may want to style Big Calendar to match your application styling. For this reason, SASS files are included with Big Calendar.

  @import 'react-big-calendar/lib/sass/styles';
  @import 'react-big-calendar/lib/addons/dragAndDrop/styles'; // if using DnD

SASS implementation provides a variables file containing color and sizing variables that you can update to fit your application. Note: Changing and/or overriding styles can cause rendering issues with your Big Calendar. Carefully test each change accordingly.
