Installation

Using NPM:
`
$ npm install --save react-native-calendars
`

Using Yarn:
`
$ yarn add 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:

`javascript
{
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 formatted date-strings, JavaScript date objects, calendar objects and UTC timestamps.

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

`javascript
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.'],
today: "Aujourd'hui"
};
LocaleConfig.defaultLocale = 'fr';
`

#### Basic parameters

`javascript
// Initially visible month. Default = now
initialDate={'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'}

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 => }
// 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

hideDayNames={true}
// Show week numbers to the left. Default = false
showWeekNumbers={true}

}}
// Enable the option to swipe between months. Default = false
enableSwipeMonths={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

`javascript
// Collection of dates that have to be marked. Default = {}
markedDates={{
'2012-05-16': {selected: true, marked: true, selectedColor: 'blue'},
'2012-05-17': {marked: true},
'2012-05-18': {marked: true, dotColor: 'red', activeOpacity: 0},
'2012-05-19': {disabled: true, disableTouchEvent: true}
}}
/>
`

You can customize a dot color for each day independently.

Multi-Dot marking

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

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

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

Period marking

`javascript
markingType={'period'}
markedDates={{
'2012-05-20': {textColor: 'green'},
'2012-05-22': {startingDay: true, color: 'green'},
'2012-05-23': {selected: true, endingDay: true, color: 'green', textColor: 'gray'},
'2012-05-04': {disabled: true, startingDay: true, color: 'green', endingDay: true}
}}
/>
`

Multi-period marking

CAUTION: This marking is only fully supported by the component because it expands its height. Usage with might lead to overflow issues.

`javascript
markingType="multi-period"
markedDates={{
'2017-12-14': {
periods: [
{startingDay: false, endingDay: true, color: '#5f9ea0'},
{startingDay: false, endingDay: true, color: '#ffa500'},
{startingDay: true, endingDay: false, color: '#f0e68c'}
]
},
'2017-12-15': {
periods: [
{startingDay: true, endingDay: false, color: '#ffa500'},
{color: 'transparent'},
{startingDay: false, endingDay: false, color: '#f0e68c'}
]
}
}}
/>
`

Custom marking allows you to customize each marker with custom styles.

`javascript
markingType={'custom'}
markedDates={{
'2018-03-28': {
customStyles: {
container: {
backgroundColor: 'green'
},
text: {
color: 'black',
fontWeight: 'bold'
}
}
},
'2018-03-29': {
customStyles: {
container: {
backgroundColor: 'white',
elevation: 2
},
text: {
color: 'blue'
}
}
}
}}
/>
`

NEW! While we still don't support multi marking type, we add the possibility to combine between period and simple.

`javascript
markingType={'period'}
markedDates={{
'2012-05-15': {marked: true, dotColor: '#50cebb'},
'2012-05-16': {marked: true, dotColor: '#50cebb'},
'2012-05-21': {startingDay: true, color: '#50cebb', textColor: 'white'},
'2012-05-22': {color: '#70d7c7', textColor: 'white'},
'2012-05-23': {color: '#70d7c7', textColor: 'white', marked: true, dotColor: 'white'},
'2012-05-24': {color: '#70d7c7', textColor: 'white'},
'2012-05-25': {endingDay: true, color: '#50cebb', textColor: 'white'}
}}
/>
`

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

#### Displaying data loading indicator

The loading indicator next to the month name will be displayed if has displayLoadingIndicator prop and the markedDates 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

`javascript
// 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',
textSectionTitleDisabledColor: '#d9e1e8',
selectedDayBackgroundColor: '#00adf5',
selectedDayTextColor: '#ffffff',
todayTextColor: '#00adf5',
dayTextColor: '#2d4150',
textDisabledColor: '#d9e1e8',
dotColor: '#00adf5',
selectedDotColor: '#ffffff',
arrowColor: 'orange',
disabledArrowColor: '#d9e1e8',
monthTextColor: 'blue',
indicatorColor: 'blue',
textDayFontFamily: 'monospace',
textMonthFontFamily: 'monospace',
textDayHeaderFontFamily: 'monospace',
textDayFontWeight: '300',
textMonthFontWeight: 'bold',
textDayHeaderFontWeight: '300',
textDayFontSize: 16,
textMonthFontSize: 16,
textDayHeaderFontSize: 16
}}
/>
`

#### Customize days titles with disabled styling

`javascript
theme={{
textSectionTitleDisabledColor: '#d9e1e8'
}}
markedDates={{
...this.getDisabledDates('2012-05-01', '2012-05-30', [0, 6])
}}
disabledDaysIndexes={[0, 6]}
/>
`

#### Advanced styling

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

https://github.com/wix/react-native-calendars/blob/master/src/calendar/header/style.ts#L60

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.tsx#L142

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

#### Individual day header styling

Using the above advanced styling, it is possible to set styles independently for each day's header. If we wanted to make the header for Sunday red, and Saturday blue, we could write something like the following:

`javascript
theme={{
'stylesheet.calendar.header': {
dayTextAtIndex0: {
color: 'red'
},
dayTextAtIndex6: {
color: 'blue'
}
}
}}
`

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

#### Overriding day component

If you need custom functionality not supported by current day component implementations you can pass your own custom day component to the calendar.

`javascript
style={[styles.calendar, {height: 300}]}
dayComponent={({date, state}) => {
return (

{date.day}

);
}}
/>
`

The dayComponent prop has to receive a RN component or a function that receive props. The dayComponent will receive such props:

- state - disabled if the day should be disabled (this is decided by base calendar component).
- marking - markedDates value for this day.
- date - the date object representing this day.

Tip: Don't forget to implement shouldComponentUpdate() for your custom day component to make the calendar perform better

If you implement an awesome day component please make a PR so that other people could use it :)

$3

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

`javascript
// 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}
// Enable or disable vertical scroll indicator. Default = false
showScrollIndicator={true}
...calendarParams
/>
`

#### Horizontal CalendarList

You can also make the CalendarList scroll horizontally. To do that you need to pass specific props to the CalendarList:

`javascript
// Enable horizontal scrolling, default = false
horizontal={true}
// Enable paging on horizontal, default = false
pagingEnabled={true}
// Set custom calendarWidth.
calendarWidth={320}
...calendarListParams
...calendarParams
/>
`

$3

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

`javascript
// 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 has 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': [{name: 'item 1 - any js object'}],
'2012-05-23': [{name: 'item 2 - any js object', height: 80}],
'2012-05-24': [],
'2012-05-25': [{name: 'item 3 - any js object'}, {name: '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 fires when the calendar is opened or closed
onCalendarToggled={calendarOpened => {
console.log(calendarOpened);
}}
// 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 ;
}}
// Specify how each date should be rendered. day can be undefined if the item is not first in that day
renderDay={(day, item) => {
return ;
}}
// Specify how empty date content with no items should be rendered
renderEmptyDate={() => {
return ;
}}
// Specify how agenda knob should look like
renderKnob={() => {
return ;
}}
// Override inner list with a custom implemented component
renderList={listProps => {
return ;
}}
// Specify what should be rendered instead of ActivityIndicator
renderEmptyData={() => {
return ;
}}
// Specify your item comparison function for increased performance
rowHasChanged={(r1, r2) => {
return r1.text !== r2.text;
}}
// Hide knob button. Default = false
hideKnob={true}
// When true and hideKnob prop is false, the knob will always be visible and the user will be able to drag the knob up and close the calendar. Default = false
showClosingKnob={false}
// 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}
}}
// If disabledByDefault={true} dates flagged as not disabled will be enabled. Default = false
disabledByDefault={true}
// If provided, a standard RefreshControl will be added for "Pull to Refresh" functionality. Make sure to also set the refreshing prop correctly
onRefresh={() => console.log('refreshing...')}
// Set this true while waiting for new data from a refresh
refreshing={false}
// Add a custom RefreshControl component, used to provide pull-to-refresh functionality for the ScrollView
refreshControl={null}
// Agenda theme
theme={{
...calendarTheme,
agendaDayTextColor: 'yellow',
agendaDayNumColor: 'green',
agendaTodayColor: 'red',
agendaKnobColor: 'blue'
}}
// Agenda container style
style={{}}
/>
