    Joda-Time

    Joda-Time

    Replacement for the Java date and time classes prior to Java SE 8

    The standard date and time classes prior to Java SE 8 are poor. By tackling this problem head-on, Joda-Time became the de facto standard date and time library for Java prior to Java SE 8. Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project. The design allows for multiple calendar systems, while still providing a simple API. The “default” calendar is the ISO8601 standard which is used by many other standards. The Gregorian, Julian, Buddhist, Coptic, Ethiopic and Islamic calendar systems are also included. Supporting classes include time zone, duration, format and parsing. Joda-Time provides a quality replacement for the Java date and time classes. Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310).

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.
