Localization and Date Formatting

includes two options for handling the date formatting and culture localization, depending on your preference of DateTime libraries. You can use either the Moment.js or Globalize.js localizers.

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


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

const localizer = momentLocalizer(moment)

const MyCalendar = props => (

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

const MyCalendar = props => (


date-fns 2.0

import { Calendar, dateFnsLocalizer } from 'react-big-calendar'
import format from 'date-fns/format'

import startOfWeek from 'date-fns/startOfWeek'
import getDay from 'date-fns/getDay'
const locales = {
  'en-US': require('date-fns/locale/en-US'),
const localizer = dateFnsLocalizer({

const MyCalendar = props => (


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

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.
