@fullcalendar/core

FullCalendar Core Types

📖 For many years, this package was the heart of FullCalendar. It played two roles:

• The Vanilla JS calendar itself — if you wrote import { Calendar } from '@fullcalendar/core', this is where it came from.
• The shared core — the essential peer dependency installed alongside every connector (React, Angular, Vue), which instantiated a Vanilla JS calendar under the hood.

That's no longer how FullCalendar works. As of v7, the connectors are self-contained and no longer need this package, and the Vanilla JS calendar has moved to its own package. Today @fullcalendar/core exists only to share a few small TypeScript type definitions across projects. You generally won't install it directly. If you're moving an existing project forward, see the Upgrading from v6 guide.

➡️ Using the Vanilla JS calendar? It moved.

The plain-JavaScript build that used to live here is now the bare fullcalendar package:

npm install fullcalendar
