React Native Calendar Events

npm npm npm

A React Native module to help access and save events to iOS and Android calendars.

Getting started

This package assumes that you already have a React Native project or are familiar with React Native. If not, checkout the official documentation for more details about getting started with React Native.


versionreact-native version
pre 2.0.0+0.40.0+

For 0.59-, you should use jetify -r


$ npm install --save react-native-calendar-events
# --- or ---
$ yarn add react-native-calendar-events

Don't forget going into the ios directory to execute a pod install.

πŸ†˜ Manual linking

Because this package targets React Native 0.60.0+, you will probably don't need to link it manually. Otherwise if it's not the case, follow this additional instructions:

πŸ‘€ See manual linking instructions


Add this line to your ios/Podfile file, then run pod install.

target 'YourAwesomeProject' do
  # …
  pod 'RNCalendarEvents', :path => '../node_modules/react-native-calendar-events'


1 - Add the following lines to android/settings.gradle:

include ':react-native-calendar-events'
project(':react-native-calendar-events').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-calendar-events/android')

2 - Add the implementation line to the dependencies in android/app/build.gradle:

dependencies {
  // ...
  implementation project(':react-native-calendar-events')

3 - Add the import and link the package in

import com.calendarevents.RNCalendarEventsPackage; // <- add the RNCalendarEventsPackage import

public class MainApplication extends Application implements ReactApplication {

  // …

  protected List<ReactPackage> getPackages() {
    List<ReactPackage> packages = new PackageList(this).getPackages();
    // …
    packages.add(new RNCalendarEventsPackage());
    return packages;

  // …

iOS specific instructions

Add RNCalendarEvents, as well as EventKit.framework to project libraries if not already done.

Setting up privacy usage descriptions may also be required depending on which iOS version is supported. This involves updating the Property List, Info.plist, with the corresponding key for the EKEventStore api. Info.plist reference.

For updating the Info.plist key/value via XCode, add a Privacy - Calendars Usage Description key with a usage description as the value. Resulting change to Info.plist should look something like:

<string>This app requires access to the calendar</string>


The following API allows for interacting with both iOS and Android device calendars. See the full list of available event fields.

import RNCalendarEvents from "react-native-calendar-events";


Get calendar authorization status. You may check for the default read/write access with no argument, or read-only access on Android by passing boolean true. iOS is always read/write.

RNCalendarEvents.checkPermissions((readOnly = false));

Returns: Promise

  • fulfilled: String - denied, restricted, authorized or undetermined
  • rejected: Error


Request calendar authorization. Authorization must be granted before accessing calendar events.

RNCalendarEvents.requestPermissions((readOnly = false));

(readOnly is for Android only, see below)

Android note: this is necessary for targeted SDK of >=23. iOS note: This method will crash, if you didn't update Info.plist. Follow carefully installation instruction.

Returns: Promise

  • fulfilled: String - denied, restricted, authorized or undetermined
  • rejected: Error

Read-Only requestPermissions (Android only)

⚠️ Note that to restrict to read-only usage on Android (iOS is always read/write) you will need to alter the included Android permissions as the AndroidManifest.xml is merged during the Android build.

You do that by altering your AndroidManifest.xml to "remove" the WRITE_CALENDAR permission with an entry like so:

<manifest xmlns:android=""
  <!-- ... -->
  <uses-permission tools:node="remove" android:name="android.permission.WRITE_CALENDAR" />

Fetch all calendar events. Returns a promise with fulfilled found events.

RNCalendarEvents.fetchAllEvents(startDate, endDate, calendars);


  • startDate: String - The start date of the range of events fetched.
  • endDate: String - The end date of the range of events fetched.
  • calendars: Array - List of calendar id strings to specify calendar events. Defaults to all calendars if empty.

These are some common issues you may run into while using react-native-calendar-events library. If you encounter something that is not listed here, try searching in GitHub issues of react-native-calendar-events.

After saving an event, it disappear form the calendar

This might be related to a sync issue. You need to be sure that the event you saved is matching what your device will keep in sync.

For iOS, you might have not all event synced. You might need to update this iOS settings in Settings > Calendar > Sync > All Events. If that's not enough, it might be worth checking iOS iCloud sync documentation.
For Android, you can have a look to Google Calendar sync problems documentation.
