import Calendar, CalendarList, Agenda from 'react-native-calendars';

All parameters for components are optional. By default the month of current local date will be displayed.

Event handler callbacks are called with calendar objects like this:

day: 1,     // day of month (1-31)
month: 1, // month of year (1-12)
year: 2017, // year
timestamp, // UTC timestamp representing 00:00 AM of this date
dateString: '2016-05-13' // date formatted as 'YYYY-MM-DD' string

Parameters that require date types accept YYYY-MM-DD formated datestrings, JavaScript date objects, calendar objects and UTC timestamps.

Calendars can be localized by adding custom locales to LocaleConfig object:

import LocaleConfig from 'react-native-calendars';

LocaleConfig.locales['fr'] =
monthNames: ['Janvier','Février','Mars','Avril','Mai','Juin','Juillet','Août','Septembre','Octobre','Novembre','Décembre'],
monthNamesShort: ['Janv.','Févr.','Mars','Avril','Mai','Juin','Juil.','Août','Sept.','Oct.','Nov.','Déc.'],
dayNames: ['Dimanche','Lundi','Mardi','Mercredi','Jeudi','Vendredi','Samedi'],
dayNamesShort: ['Dim.','Lun.','Mar.','Mer.','Jeu.','Ven.','Sam.']

LocaleConfig.defaultLocale = 'fr';


Basic parameters

// Initially visible month. Default = Date()
// Minimum date that can be selected, dates before minDate will be grayed out. Default = undefined
// Maximum date that can be selected, dates after maxDate will be grayed out. Default = undefined
// Handler which gets executed on day press. Default = undefined
onDayPress=(day) => console.log('selected day', day)
// Month format in calendar title. Formatting values:
monthFormat='yyyy MM'
// Handler which gets executed when visible month changes in calendar. Default = undefined
onMonthChange=(month) => console.log('month changed', month)
// Hide month navigation arrows. Default = false
// Replace default arrows with custom ones (direction can be 'left' or 'right')
renderArrow=(direction) => (<Arrow />)
// Do not show days of other months in month page. Default = false
// If hideArrows=false and hideExtraDays=false do not swich month when tapping on greyed out
// day from another month that is visible in calendar page. Default = false
// If firstDay=1 week starts from Monday. Note that dayNames and dayNamesShort should still start from Sunday.

Date marking

// Collection of dates that have to be marked. Default =
'2012-05-16': selected: true, marked: true,
'2012-05-17': marked: true,
'2012-05-18': disabled: true

// Collection of dates that have to be colored in a special way. Default =
'2012-05-20': [textColor: 'green'],
'2012-05-22': [startingDay: true, color: 'green'],
'2012-05-23': [endingDay: true, color: 'green', textColor: 'gray'],
'2012-05-04': [startingDay: true, color: 'green', endingDay: true, color: 'green']

// Date marking style [simple/interactive]. Default = 'simple'

Displaying data loading indicator

The loading indicator next to month name will be displayed if <Calendar /> has displayLoadingIndicator property and markedDays collection does not have a value for every day of the month in question. When you load data for days, just set [] or special marking value to all days in markedDates collection.

Customizing look & feel

// Specify style for calendar container element. Default =
borderWidth: 1,
borderColor: 'gray',
height: 350

// Specify theme properties to override specific styles for calendar parts. Default =
calendarBackground: '#ffffff',
textSectionTitleColor: '#b6c1cd',
selectedDayBackgroundColor: '#00adf5',
selectedDayTextColor: '#ffffff',
todayTextColor: '#00adf5',
dayTextColor: '#2d4150',

dotColor: '#00adf5',

<CalendarList /> is scrollable semi-infinite calendar composed of <Calendar /> components. Currently it is possible to scroll 4 years back and 4 years to the future. All paramters that are available for <Calendar /> are also available for this component. There are also some additional params that can be used:

// Callback which gets executed when visible months change in scroll view. Default = undefined
onVisibleMonthsChange=(months) => console.log('now these months are visible', months);
// Max amount of months allowed to scroll to the past. Default = 50
// Max amount of months allowed to scroll to the future. Default = 50
// Enable or disable scrolling of calendar list


An advanced agenda component that can display interactive listings for calendar day items.

// the list of items that have to be displayed in agenda. If you want to render item as empty date
// the value of date key kas to be an empty array []. If there exists no value for date key it is
// considered that the date in question is not yet loaded
'2012-05-22': [text: 'item 1 - any js object'],
'2012-05-23': [text: 'item 2 - any js object'],
'2012-05-24': [],
'2012-05-25': [text: 'item 3 - any js object',text: 'any js object'],

// callback that gets called when items for a certain month should be loaded (month became visible)
loadItemsForMonth=(mongh) => console.log('trigger items loading')
// callback that gets called on day press
onDayPress=(day)=>console.log('day pressed')
// callback that gets called when day changes while scrolling agenda list
onDayChange=(day)=>console.log('day changed')
// initially selected day
// specify how each item should be rendered in agenda
renderItem=(item, firstItemInDay) => return (<View />);
// specify how each date should be rendered. day can be undefined if the item is not first in that day.
renderDay=(day, item) => return (<View />);
// specify how empty date content with no items should be rendered
renderEmptyDate=() => return (<View />);
// specify your item comparison function for increased performance
rowHasChanged=(r1, r2) => return r1.text !== r2.text
// Hide knob button. Default = false
// agenda theme
theme =
agendaDayTextColor = 'yellow',
agendaDayNumColor = 'green',
agendaTodayColor = 'red'
