    FullCalendar

    FullCalendar

    Full-sized drag & drop event calendar

    FullCalendar generates real React virtual DOM nodes so you can leverage Fiber, React's highly optimized rendering engine. With over 300 settings, and more being added every release, FullCalendar can do just about anything. Reduce your project's bundle size by using FullCalendar's modular plugins. With over 10 years of open source and over 100 contributors, FullCalendar will always have a free and open source core. 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).

    bootstrap-datepicker

    bootstrap-datepicker

    A datepicker for twitter bootstrap

    Bootstrap-datepicker provides a flexible datepicker widget in the Bootstrap style. Versions are incremented according to semver. As with bootstrap’s own plugins, datepicker provides a data-api that can be used to instantiate datepickers without the need for custom javascript. You can disable datepicker’s data-api in the same way as you would disable other bootstrap plugins. Most options can be provided via data-attributes. An option can be converted to a data-attribute by taking its name, replacing each uppercase letter with its lowercase equivalent preceded by a dash, and prepending “data-date-” to the result. Methods are called on a datepicker by calling the datepicker function with a string first argument, followed by any arguments the method takes.

    pickadate

    pickadate

    jQuery date and time input picker

    There’s a tonne of options to customize the date and time pickers, such as month/year selectors, time intervals, etc. There’s also a rich API to extend the functionality of the picker. Some examples are displayed on Codepen. When using the “classic” theme, it is important to have a wrapper div with position, relative around the source input to ensure the picker is sized according to the input element it is bound to. Supports all modern browsers – and IE8+. Specifically, v3 has been tested with Chrome MWA, Firefox MWA, Opera MWA, Safari Mi, Internet Explorer W, Blackberry 6.0+ and Android 3.2+ browsers. Make sure to also include the legacy.js file along for the oldie browsers. pickadate.js is an open source project, shared under an MIT license. All themes are generated using LESS and compiled from the lib/themes-source folder into the lib/themes folder. The translations live in the lib/translations folder. There are currently 43 language translations included.

    react-big-calendar

    react-big-calendar

    gcal/outlook like calendar component

    An events calendar component built for React and made for modern browsers (read: IE10+) and uses flexbox over the classic tables-ception approach. Styles can be found at: react-big-calendar/lib/css/react-big-calendar.css, and should be included on the page with the calendar component. Also make sure that your calendar's container element has a height, or the calendar won't be visible. Date internationalization and localization is hard and react-big-calendar doesn't even attempt to solve that problem. Instead you can use one of the many excellent solutions already out there, via adapters called "localizers". Big Calendar comes with two localizers for use with Globalize.js or Moment.js. Choose the localizer that best suits your needs, or write your own. Whatever you do, you'll need to set it up before you can use the calendar (you only need to set it up once).

    Material Calendar View

    Material Calendar View

    A Material design back port of Android's CalendarView

    A Material design backport of Android's CalendarView. The goal is to have a Material look and feel, rather than 100% parity with the platform's implementation. Material CalendarView 2.0 comes in with a major change into the core of it's API, we transitioned from using java.util.Calendar to java.time.LocalDate. Also that should not impact the public api (we are still using CalendarDay), both Calendar and LocalDate function a little bit differently. One example of that: Months are now indexed from 1 (January) to 12 (December). You can access from the LocalDate from CalendarDay using getDate().
