react-native-calendar-picker

This is a Calendar Picker Component for React Native

To use the calendar you just need to:

npm install --save react-native-calendar-picker

Note: react-native-calendar-picker v5 is a complete re-write of the calendar. This calendar is now written using ES6 syntax. I kept most of the same functionalities and added support for date ranges.

If you need the old code I saved it on a branch v4

Prerequisites

CalendarPicker requires Moment JS. Date props may be anything parseable by Moment: Javascript Date, Moment date, or ISO8601 datetime string.

npm install --save moment

Example

import React, { Component } from 'react';
import {
  StyleSheet,
  Text,
  View
} from 'react-native';
import CalendarPicker from 'react-native-calendar-picker';

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      selectedStartDate: null,
    };
    this.onDateChange = this.onDateChange.bind(this);
  }

  onDateChange(date) {
    this.setState({
      selectedStartDate: date,
    });
  }
  render() {
    const { selectedStartDate } = this.state;
    const startDate = selectedStartDate ? selectedStartDate.toString() : '';
    return (
      <View style={styles.container}>
        <CalendarPicker
          onDateChange={this.onDateChange}
        />

        <View>
          <Text>SELECTED DATE:{ startDate }</Text>
        </View>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#FFFFFF',
    marginTop: 100,
  },
});

Styles

Some styles will overwrite some won't. For instance:

If you provide textStyle with fontFamily and color, out of ranges dates will not apply your color, just fontFamily.

Order of precedence:

defaultColor => textStyle => selectedDayColor
defaultTodayBackgroundColor => todayBackgroundColor
defaultBackgroundColor => selectedDayColor
defaultTextStyles => textStyle => selectedDayTextColor

import React, { Component } from 'react';
import {

  Text,

} from 'react-native';
import CalendarPicker from 'react-native-calendar-picker';

export default class App extends Component {

    } else {

        selectedStartDate: date,
        selectedEndDate: null,
      });
    }
  }

  render() {

    const minDate = new Date(); // Today
    const maxDate = new Date(2017, 6, 3);

  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#FFFFFF',
    marginTop: 100,
  },
});

Custom styling individual dates

let today = moment();
let day = today.clone().startOf('month');
let customDatesStyles = [];
while(day.add(1, 'day').isSame(today, 'month')) {
  customDatesStyles.push({
    date: day.clone(),
    // Random colors
    style: {backgroundColor: '#'+('#00000'+(Math.random()*(1<<24)|0).toString(16)).slice(-6)},
    textStyle: {color: 'black'}, // sets the font color
    containerStyle: [], // extra styling for day container
  });
}

render() {
  return (
    <CalendarPicker
      todayTextStyle={{fontWeight: 'bold'}}
      todayBackgroundColor={'transparent'}
      customDatesStyles={customDatesStyles}
      minDate={today}
    />
  );
}
