Usage

If you want to see more examples and experiment, run the examples locally.

git clone git@github.com:quidone/react-native-calendars.git
cd react-native-calendars
yarn install
cd example && yarn install && yarn ios

Base case

import React, {useState} from 'react';
import {MonthCalendar} from '@quidone/react-native-calendars';

const App = () => {
  const [selected, setSelected] = useState(null);

  return (
    <MonthCalendar
      selectedDay={selected}
      onDayChanged={({day}) => {
        setSelected(day);
      }}
    />
  );
};

export default App;

Multiple selection

If you needed a more complex date selection behavior, you can do the following:

const App = () => {
  const [days, setDays] = useState([]);

  return (
    <MonthCalendar
      selectedDay={null} // Important! This will disable the internal date selection state
      markedDays={days.map(day => [day, {selected: true}])}
      onDayPress={({day}) => {
        setDays(prev => {
          if (prev.includes(day)) {
            return prev.filter(p => p !== day);
          } else {
            return [...prev, day];
          }
        });
      }}
    />
  );
};

Localization

dayjs works under the hood of calendars and all localization settings are taken from it.

For example, let's set the French localization:

import React, {useState} from 'react';
import {MonthCalendar} from '@quidone/react-native-calendars';
import 'dayjs/locale/fr' // import the French localization

const App = () => {
  return (<MonthCalendar locale={'fr'}/>);
};

export default App;

You also can set your own settings:

<MonthCalendar
  locale={{
    weekStart: 0,
    months: [/* list of month names */],
    weekdaysMin: [/* list of weekdays */],
    ...
  }}
/>

Customization

Theme

Theme settings allows you to easily change display of calendars: element sizes, paddings and even animations

<MonthCalendar
  theme={{
    calendarPaddingHorizontal: 16,
    monthTitleColor: '#000000',
    monthTitleFontSize: 17,
    weekDayTitleColor: '#707070',
    weekDayTitleFontSize: 12,
    pagePaddingTop: 4,
    pagePaddingBottom: 4,
    pageBetweenRows: 2,
    dayContainerSize: 40,
    dayFontSize: 17,
    dayBgColor: {value: 'transparent', type: 'timing', option: {duration: 50}},
    daySelectedBgColor: {value: '#2C98F0', type: 'timing', option: {duration: 50}},
    dayColor: {value: '#000000', type: 'timing', option: {duration: 50}},
    daySelectedColor: {value: '#ffffff', type: 'timing', option: {duration: 50}},
    daySecondaryOpacity: 0.4,
    dayDisabledOpacity: 0.4,
    dayDotSize: 5,
  }}
/>

Styles

Sometimes the theme configuration may not be enough. When you can use the styles:

<MonthCalendar
  containerStyle={{/* ... */}}
  monthRowStyle={{/* ... */}}
  monthTitleStyle={{/* ... */}}
  weekDayRowStyle={{/* ... */}}
  weekDayContainerStyle={{/* ... */}}
  weekDayTitleStyle={{/* ... */}}
  pageContainerStyle={{/* ... */}}
  dayRowStyle={{/* ... */}}
  dayContainerStyle={{/* ... */}}
  dayTextStyle={{/* ... */}}
  dayDotRowStyle={{/* ... */}}
  dayDotStyle={{/* ... */}}
/>

Some style properties may accept selectors that allow you to fine-tune styles

<MonthCalendar
  dayContainerStyle={({
    day,
    isSelected,
    isToday,
    isDisabled,
    isSecondary,
  }) => {
    return {/* ... */}
  }}
/>

It is also possible to render your own components.

Marked days

You can set a set of dates to be selected, disabled, or marked with dots

Let's look as a simple example:

<MonthCalendar
  markedDays={[
    ['2023-01-01', {selected: true}], // one day
    ['2023-01-01', '2023-01-14', {dots: [{color: 'red'}]}], // range from '2023-01-01' to '2023-01-14'
  ]}
/>

The date '2023-01-01' will contain the selected flag and a red dot. The following records add or override data. If the dates with dots intersect, then the dots will be merged into a new list. You can set a key for dots that will allow you to distinguish and override these dots.

Selector

There is support for a selector that is called when new dates appear

<MonthCalendar
  markedDays={({start, end}) => {
    return [[start, end, {dots: [{color: 'orange'}]}]]
  }}
/>

You can also pass a list and a selector together.

<MonthCalendar
  markedDays={{
    list: [/* records */],
    selector: (info) => [/* records */]
  }}
/>
