React Native Calendar

Overview

High-quality, modern, fast interactive calendar built specifically with performance in mind. Supports gestures and animations.

Main Features

- done - in progress - not supported

Supported Versions

React Native ecosystem is evolving rapidly, fixing and introducing many bugs. For example react-native-calendar doesn't work for React Native 0.63.3 because this version doesn't support ScrollView contentOffset property for Android, while 0.63.4 should work.

Because of this we provide a table of supported versions.

react-native-reanimated and react-native-gesture-handler are peerDependencies and need to be installed beforehand.

Usage

import React from 'react';
import { View } from 'react-native';
import { Calendar } from '@breeffy/react-native-calendar';

export const CalendarSheet = () => {
  return (
    <Calendar
      selectionMode="singleDay"
      scrollMode="oneMonth"
      monthsBefore={12}
      monthsAfter={24}
    />
  );
};

type CalendarProps = {
  /**
   * Initial month to be shown.
   * If not provided, year and month of current local datetime will be selected.
   */

   * Amount of months, before initial year and month,

   * @defaultValue `multipleMonths`
   */
  scrollMode?: 'oneMonth' | 'multipleMonths' | 'anyOffset';

  /**

  /**
   * Callback is called when state of a day changes,
   * i.e. it's selected / unselected.
   *
   * **Note:** for `singleDay` selection mode day unselected by
   * other selected day is not notified.
   * You can understand it was unselected by checking
   * current `selectionMode`.
