Localization and Date Formatting

includes three 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 or date-fns 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 => (


Globalize.js v0.1.1

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

const localizer = globalizeLocalizer(globalize)

const MyCalendar = props => (


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 => (


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.
