The official Calendar app for Nextcloud, a web-based frontend for managing and syncing events via CalDAV. It supports event invitations, free/busy scheduling, reminders, WebCal subscriptions, and integration with other Nextcloud apps like Contacts, Talk, Tasks, and Deck.

Use cases

• manage a self-hosted calendar in the browser
• sync events across devices via CalDAV
• subscribe to external webcal calendars
• invite attendees and check free/busy availability
• set event reminders via browser and email
• view tasks with due dates in a calendar view
• share calendar links for appointment booking

When to choose

• you already run a Nextcloud instance and need calendar functionality
• you want a self-hosted, privacy-friendly alternative to Google Calendar
• you need CalDAV sync with mobile and desktop clients
• you want tight integration with Nextcloud Contacts, Talk, and Tasks

When to avoid

• you are not using Nextcloud server as the backend
• you need a standalone calendar server without Nextcloud
• you need offline-first desktop calendar features beyond the browser
