    CalendarKit

    CalendarKit

    Calendar for Apple platforms in Swift

    CalendarKit is a Swift calendar UI library for iOS and Mac Catalyst. It looks similar to the Apple Calendar app out-of-the-box, while allowing customization when needed. CalendarKit is composed of multiple modules which can be used together or independently. CalendarKit requires EventDataSource to return an array of objects conforming to EventDescriptor protocol, specifying all the information needed to display a particular event. You're free to use a default Event class as a model or create your own class conforming to the EventDescriptor protocol. CalendarKit supports localization and uses iOS default locale to display month and day names. First day of the week is also selected according to the iOS locale. By default, CalendarKit looks similar to the Apple Calendar app and fully supports Dark Mode. If needed, CalendarKit's look can be easily customized.

    React Native Calendars

    React Native Calendars

    Customizable React-Native calendar components

    This module includes various customizable React-Native calendar components. The package is both Android and iOS compatible. This project is compatible with Expo/CRNA (without ejecting), and the examples have been published on Expo. The solution is implemented in JavaScript so no native module linking is required. All parameters for components are optional. By default the month of current local date will be displayed. Parameters that require date types accept YYYY-MM-DD formatted date-strings, JavaScript date objects, calendar objects and UTC timestamps. Calendars can be localized by adding custom locales to LocaleConfig object. Keep in mind that different marking types are not compatible. You can use just one marking style for a calendar. If you need custom functionality not supported by current day component implementations you can pass your own custom day component to the calendar.
