Open Source TypeScript Calendar Software

React-Calendar is a customizable React component for selecting dates and navigating calendar periods. Users can choose individual days, months, years, or decades through progressively broader views. Range selection allows applications to capture both the beginning and end of a period. Multiple calendar systems are supported, including Gregorian, ISO 8601, Hebrew, and Islamic configurations. Localization relies on browser internationalization capabilities and works with virtually any language. Developers can control displayed periods, views, selectable ranges, values, and styling through component props. The package requires no Moment.js dependency and is designed to remain lightweight and easy to integrate into modern React applications.

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).

React-Date-Picker is a React component that combines editable date fields with a popup calendar interface. Users can enter dates manually or choose them visually through its integrated React-Calendar component. It supports selecting days, months, years, and broader periods depending on the configured detail level. Localization uses standard language tags and browser locale information without requiring Moment.js. Developers can define minimum and maximum dates, formatting rules, calendar behavior, placeholders, and custom icons. Accessibility options include dedicated labels for calendar controls, date fields, native input, and clearing actions. The component can be styled with its default CSS or customized to match an application's interface.

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.

Reqcore is an Applicant Tracking System built for companies receiving more applicants than they can effectively review. Instead of forcing recruiters to manually screen hundreds of résumés, Reqcore evaluates every applicant against role-specific hiring criteria and turns large applicant pools into a clear, prioritized shortlist. Each evaluation includes an explanation of why the candidate matches, helping hiring teams identify strong applicants without losing them in the noise. Reqcore is best suited to companies whose main recruitment challenge is reviewing applicants—not attracting more of them. It combines applicant tracking, candidate evaluation, pipeline management, and team collaboration in one modern hiring platform. Key Benefits: * Built for Applicant Overload: Manage roles receiving hundreds or thousands of applications without overwhelming recruiters. * Criteria-Based Evaluation: Evaluate every applicant against the qualifications and requirements that matter for
