    iCalendar Generator

    iCalendar Generator

    Generate calendars in the iCalendar format

    ...The format of such calendars is defined in RFC 5545, which is not a pleasant reading experience. This package implements RFC 5545 and some extensions from RFC 7986 to provide you an easy-to-use API for creating calendars. It's not our intention to implement these RFC's entirely but to provide a straightforward API that's easy to use.

    FullCalendar

    FullCalendar

    Full-sized drag & drop event calendar

    ...Level-up by purchasing premium plugins and support. FullCalendar seamlessly integrates with the React JavaScript framework. It provides a component that exactly matches the functionality of FullCalendar’s standard API. This is more than a mere “connector”. It tells the core FullCalendar package to begin rendering with React virtual DOM nodes as opposed to the Preact nodes it normally uses, transforming FullCalendar into a “real” React component. You can learn a bit more from this blog post (more info to come).

    Joda-Time

    Joda-Time

    Replacement for the Java date and time classes 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. ...

    Marl

    Marl

    A hybrid thread / fiber task scheduler written in C++ 11

    marl is a lightweight C++ job system that schedules tasks on a pool of worker threads and runs them using cooperative fibers for high throughput. By decoupling “tasks” from OS threads, it minimizes context switches and lets workloads with fine-grained synchronization scale efficiently. The API is intentionally small—post tasks, wait on fences, and express dependencies—so you can retrofit it into existing engines without adopting a heavyweight framework. Under the hood, fibers allow tasks to yield while waiting, keeping cores busy without blocking threads. The runtime is portable across platforms and integrates cleanly with real-time systems that must minimize latency jitter. ...
