Cross-platform gcal/outlook like calendar component for React Native.
It's a hard task to debug this library on three platforms. I usually develop with the Web version first, then confirm its functionality with real devices. My PC is Linux and my phone is Android, so on Android it is easy to test, but to debug on iOS, I have to bring my Macbook Pro from my garage and connect my wife's iPhone and test it. Every time I launch my Macbook Pro, it requires the Xcode update or even full system update. It takes so long time to start debug. As React Native works on iOS better than Android, I always sometimes skip testing it, so there should be a bug on iOS. If you help me debug it, I would much appreciate!
- Cross Platform: Runs on the Web, iOS, Android with the power of React
- Type-safe: Fully written in TypeScript
- Customizable: Able to provide your own theme, and pass your component to render.
- Lightweight: ~37.4KB, dependency is

npm install --save react-native-big-calendar
Or if you use Yarn:
yarn add react-native-big-calendar
Please ensure peer dependencies are installed.
npm install react react-nativeIf you use TypeScript ensure @types/react and @types/react-native is installed. react-native-big-calendar internally uses them.
npm install --save-dev @types/react @types/react-nativeIf you are using this module on the Web, please install react-native-web.
npm install react-native-webIf you are using Create React App, you are ready to go 🎉

| 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. |

type EventRenderer<T> = (

touchableOpacityProps: CalendarTouchableOpacityProps,
) => ReactElement | nullFor more information, see Storybook
interface ICalendarEventBase {
start: Date
end: Date
title: string
children?: ReactElement | null
}All day events should start and end on 0 in hour, minutes, and seconds (T00:00:00). For example:
{
title: 'all day event',
start: "2021-12-24T00:00:00.000Z",
end: "2021-12-24T00:00:00.000Z", // same date as `start`
}You can specify custom event render function which receives the calculated TouchableOpacity prop and event.
- The function
renderEventmust return aReactElement. - The component should be wrapped inside a
TouchableOpacityor any DOM element which accepts positioning and click events (onPress, ...).
export interface MyCustomEventType {
color: string
}
const renderEvent = <T extends ICalendarEventBase>(
event: T,
touchableOpacityProps: CalendarTouchableOpacityProps,
) => (
<TouchableOpacity {...touchableOpacityProps}>
<Text>{`My custom event: ${event.title} with a color: ${event.color}`}</Text>
</TouchableOpacity>
)
<Calendar renderEvent={renderEvent} />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: ICalendarEventBase[] = [
{
title: 'Custom reminder',
start: dayjs().set('hour', 16).set('minute', 0).toDate(),
end: dayjs().set('hour', 17).set('minute', 0).toDate(),
children: eventNotes,
},
]You can customize the calendar by passing the theme prop. theme should be like this interface partially:
export interface Palette {
main: string
contrastText: string
}
export interface ThemeInterface {
palette: {
primary: Palette
nowIndicator: string
gray: {
100: string
200: string
300: string
500: string
800: string
}
}
isRTL: boolean
typography: {
fontFamily?: string
xs: Typography
sm: Typography
xl: Typography
}
eventCellOverlappings: readonly Palette[]
moreLabel: TextStyle
}For example:
const darkTheme = {
palette: {
primary: {
main: '#6185d0',
contrastText: '#000',
},
gray: {
'100': '#333',
'200': '#666',
'300': '#888',
'500': '#aaa',
'800': '#ccc',
},
},
}
<Calendar
height={SCREEN_HEIGHT}
theme={darkTheme}
/>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:
