Installation

$ npm install --save react-native-calendars

The solution is implemented in JavaScript so no native module linking is required.

Usage

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';

Calendar

Basic parameters

<Calendar 
  // Initially visible month. Default = Date()
  current={'2012-03-01'}
  // Minimum date that can be selected, dates before minDate will be grayed out. Default = undefined
  minDate={'2012-05-10'}
  // Maximum date that can be selected, dates after maxDate will be grayed out. Default = undefined
  maxDate={'2012-05-30'}
  // Handler which gets executed on day press. Default = undefined
  onDayPress={(day) => {console.log('selected day', day)}}
  // Month format in calendar title. Formatting values: http://arshaw.com/xdate/#Formatting
  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
  hideArrows={true}
  // 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
  hideExtraDays={true}
  // 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
  disableMonthChange={true}
  // If firstDay=1 week starts from Monday. Note that dayNames and dayNamesShort should still start from Sunday.
  firstDay={1}
/>

Date marking

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

<Calendar 
  // Collection of dates that have to be colored in a special way. Default = {}
   markedDates={
    {'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'
  markingType={'interactive'}
/>

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

<Calendar 
  // Specify style for calendar container element. Default = {}
  style={{
    borderWidth: 1,
    borderColor: 'gray',
    height: 350
  }}
  // Specify theme properties to override specific styles for calendar parts. Default = {}
  theme={{
    calendarBackground: '#ffffff',
    textSectionTitleColor: '#b6c1cd',
    selectedDayBackgroundColor: '#00adf5',
    selectedDayTextColor: '#ffffff',
    todayTextColor: '#00adf5',
    dayTextColor: '#2d4150',
    textDisabledColor: '#d9e1e8',
    dotColor: '#00adf5',
    selectedDotColor: '#ffffff',
    arrowColor: 'orange',
    monthTextColor: 'blue'
  }}
/>

CalendarList

<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:

<CalendarList
  // 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
  pastScrollRange={50}
  // Max amount of months allowed to scroll to the future. Default = 50
  futureScrollRange={50}
  // Enable or disable scrolling of calendar list
  scrollEnabled={true}
  ...calendarParams
/>

Agenda

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

<Agenda
  // 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
  items={
    {'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
  selected={'2012-05-16'}
  // 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
  hideKnob={true}
  // agenda theme
  theme = {{
    ...calendarTheme,
    agendaDayTextColor = 'yellow',
    agendaDayNumColor = 'green',
    agendaTodayColor = 'red'
  }}
  // agenda container style
  style = {{}}
/>
