## What it is
FullCalendar is a full-sized, drag-and-drop event calendar library for JavaScript with connectors for React, Vue, Angular, Preact, and web components. It offers month, week, day, list, and multi-month views via a plugin architecture, with premium scheduler features available under a commercial license.

## Use cases
- add an event calendar to a React app
- display a monthly schedule with drag-and-drop events
- build a booking calendar in Vue
- render a week/time-grid view of appointments
- show a list of upcoming events in Angular
- embed a calendar widget in a web app

## When to choose
- you need a mature, feature-rich JavaScript calendar with framework connectors
- you want drag-and-drop event editing and multiple calendar views out of the box
- you need internationalization, timezone support, and accessibility features

## When to avoid
- you need timeline or resource-scheduling views without paying for a commercial license
- you need server-side or backend scheduling logic, which is out of scope
- you want a tiny bundle and only need a simple date picker rather than a full calendar
