FullCalendar is a framework-agnostic UI library and JavaScript calendar component designed for building interactive event scheduling interfaces. It provides tools for managing time-based data, including an integrated iCal feed parser for importing external calendar files and recurring schedules into a unified web view.
The library features a system for event scheduling and management, enabling users to reschedule entries via drag-and-drop, adjust event durations by resizing, and highlight specific time ranges for selection. It supports multiple date views, such as month, week, day, and list formats, and includes a plugin-based extension model to add specific views or interaction capabilities.
The project covers broad functional areas including event lifecycle management, calendar content localization for different timezones and languages, and accessibility support for keyboard and screen-reader navigation. Visual appearance and component content can be modified through CSS and injection hooks for UI customization.
Integration with various frontend environments is provided through dedicated connectivity layers and framework-specific wrapper layers.
