<Calendar /> Props are:

name	required	type	description
events	yes	ICalendarEvent<T>[]	The events which will be rendered on the calendar. You can extend the type ICalendarEvent by providing a value to generic type T (see ./stories/events.tsx for an example). with optional children to display custom components inside the event, and optional event renderer function to take complete control over the rendered event (advanced feature). Events that occur during the same time range will be layered, offset, and given a unique color.
height	yes	number	Calendar height.
hideNowIndicator	no	boolean	Hides the indicator for the current time. By default the now indicator is shown.
onPressEvent	no	(event: ICalendarEvent<T>) => void	Event handler which will be fired when the user clicks an event.
onChangeDate	no	([start: Date, end: Date]) => void	Event handler which will be fired when the current date range changed.
onPressCell	no	(date: Date) => void	Event handler which will be fired when the current date cell is clicked. The minute set to 0.
onPressDateHeader	no	(date: Date) => void	Event handler which will be fired when the user clicks a date from the header.
mode	no	'month' | 'week' | '3days' | 'day' | 'custom'
style	no	import('react-native').ViewStyle
eventCellStyle	no	ViewStyle | (event: ICalendarEvent<T>) => ViewStyle	The style of Event cell. Accepts either style object (static) or function (dynamic).
scrollOffsetMinutes	no	number	Scroll to specific minutes in a day. e.g.) set 480 to scroll to 8am when the calendar rendered.
date	no	Date	Initial date. Defualts to Date
swipeEnabled	no	boolean
showTime	no	boolean
ampm	no	boolean	Use 12 hours time format instead of 24 hours.
weekStartsOn	no	0 | 1 | 2 | 3 | 4 | 5 | 6	Which day the week starts on. Sunday is 0.
weekEndsOn	no	0 | 1 | 2 | 3 | 4 | 5 | 6	Which day the week ends on. Sunday is 0.
locale	no	string	Custom locale. See I18n section
overlapOffset	no	number	Adjusts the indentation of events that occur during the same time period. Defaults to 20 on web and 8 on mobile.
isRTL	no	boolean	Switches the direction of the layout for use with RTL languages. Defaults to false.
renderEvent	no	EventRenderer	Custom event renderer. See below type definition.
renderHeader	no	HeaderRenderer	Custom header renderer.

EventRenderer

type EventRenderer<T> = (
  event: ICalendarEvent<T>,
  touchableOpacityProps: CalendarTouchableOpacityProps,
) => ReactElement | null

For more information, see Storybook

ICalendarEvent

interface ICalendarEventBase<T> {
  start: Date
  end: Date
  title: string
  children?: ReactElement | null
}

export type ICalendarEvent<T = any> = ICalendarEventBase<T> & T

Using a custom event render function

You can specify custom event render function which receives the calculated TouchableOpacity prop and event.

• The function renderEvent must return a ReactElement.
• The component should be wrapped inside a TouchableOpacity or any DOM element which accepts positioning and click events (onPress, ...).

export interface MyCustomEventType {
  color: string
}

const renderEvent = (
  event: ICalendarEvent<MyCustomEventType>,
  touchableOpacityProps: CalendarTouchableOpacityProps,
) => (
  <TouchableOpacity {...touchableOpacityProps}>
    <Text>{`My custom event: ${event.title} with a color: ${event.color}`}</Text>
  </TouchableOpacity>
)

<Calendar renderEvent={renderEvent} />

Displaying event's notes

Your events can contain a prop children An example can be found here.

const eventNotes = useMemo(
  () => (
    <View style={{ marginTop: 3 }}>
      <Text style={{ fontSize: 10, color: 'white' }}> Phone number: 555-123-4567 </Text>
      <Text style={{ fontSize: 10, color: 'white' }}> Arrive 15 minutes early </Text>
    </View>
  ),
  [],
)

export const myEvents: ICalendarEvent[] = [
  {
    title: 'Custom reminder',
    start: dayjs().set('hour', 16).set('minute', 0).toDate(),
    end: dayjs().set('hour', 17).set('minute', 0).toDate(),
    children: eventNotes,
  },
]

I18n

Please specity your locale via locale prop and import day.js locale file:

import 'dayjs/locale/ja'

<Calendar
  locale="ja"
  {/* ... */}
/>

You can find your dayjs locale here:
