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-th';

LocaleConfig.locales['th'] = {
  monthNames: ['มกราคม', 'กุมภาพันธ์', 'มีนาคม', 'เมษายน', 'พฤษภาคม', 'มิถุนายน', 'กรกฎาคม', 'สิงหาคม', 'กันยายน', 'ตุลาคม', 'พฤศจิกายน', 'ธันวาคม'],
  monthNamesShort: ['ม.ค.', 'ก.พ.', 'ม.ค.', 'เม.ย.', 'พ.ค.', 'มิ.ย.', 'ก.ค.', 'ส.ค.', 'ก.ย.', 'ต.ค.', 'พ.ย', 'ธ.ค.'],
  dayNames: ['อาทิตย์', 'จันทร์', 'อังคาร', 'พุธ', 'พฤหัสบดี', 'ศุกร์', 'เสาร์'],
  dayNamesShort: ['อา.', 'จ.', 'อ.', 'พ.', 'พฤ.', 'ศ.', 'ส.']
};

LocaleConfig.defaultLocale = 'th';

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 switch 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}
  // Hide day names. Default = false
  hideDayNames={true}
/>

Date marking

!Disclaimer! Make sure that markedDates param is immutable. If you change markedDates object content but the reference to it does not change calendar update will not be triggered.

Dot 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}
  }}
/>

Multi-Dot marking

Use markingType = 'multi-dot' if you want to display more than one dot. Both the Calendar and CalendarList control support multiple dots by using 'dots' array in markedDates. The properties 'key' and 'color' are mandatory while 'selectedColor' is optional. If selectedColor is omitted then 'color' will be used for selected dates.

const vacation = {key:'vacation', color: 'red', selectedColor: 'blue'};
const massage = {key:'massage', color: 'blue', selectedColor: 'blue'};
const workout = {key:'workout', color: 'green'};

<Calendar
  markedDates={{
    '2017-10-25': {dots: [vacation, massage, workout], selected: true},
    '2017-10-26': {dots: [massage, workout], disabled: true},
  }},
  markingType={'multi-dot'}
/>

Interval marking

<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/multi-dot]. Default = 'simple'
  markingType={'interactive'}
/>

Keep in mind that different marking types are not compatible. You can use just one marking style for calendar.

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={{
    backgroundColor: '#ffffff',
    calendarBackground: '#ffffff',
    textSectionTitleColor: '#b6c1cd',
    selectedDayBackgroundColor: '#00adf5',
    selectedDayTextColor: '#ffffff',
    todayTextColor: '#00adf5',
    dayTextColor: '#2d4150',
    textDisabledColor: '#d9e1e8',
    dotColor: '#00adf5',
    selectedDotColor: '#ffffff',
    arrowColor: 'orange',
    monthTextColor: 'blue',
    textDayFontFamily: 'monospace',
    textMonthFontFamily: 'monospace',
    textDayHeaderFontFamily: 'monospace',
    textDayFontSize: 16,
    textMonthFontSize: 16,
    textDayHeaderFontSize: 16
  }}
/>

Advanced styling

If you want to have complete control over calendar styles you can do it by overriding default style.js files. For example, if you want to override calendar header style first you have to find stylesheet id for this file:

https://github.com/wix/react-native-calendars/blob/master/src/calendar/header/style.js#L4

In this case it is 'stylesheet.calendar.header'. Next you can add overriding stylesheet to your theme with this id.

https://github.com/wix/react-native-calendars/blob/master/example/src/screens/calendars.js#L56

theme={{
  arrowColor: 'white',
  'stylesheet.calendar.header': {
    week: {
      marginTop: 5,
      flexDirection: 'row',
      justifyContent: 'space-between'
    }
  }
}}

Disclaimer: issues that arise because something breaks after using stylesheet override will not be supported. Use this option at your own risk.

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={(month) => {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'}
  // 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'}
  // 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}
  // 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 how agenda knob should look like
  renderKnob={() => {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}
  // By default, agenda dates are marked if they have at least one item, but you can override this if needed
  markedDates={{
    '2012-05-16': {selected: true, marked: true},
    '2012-05-17': {marked: true},
    '2012-05-18': {disabled: true}
  }}
  // agenda theme
  theme={{
    ...calendarTheme,
    agendaDayTextColor: 'yellow',
    agendaDayNumColor: 'green',
    agendaTodayColor: 'red',
    agendaKnobColor: 'blue'
  }}
  // agenda container style
  style={{}}
/>
