UniCalendar

A unified calendar view for Obsidian that aggregates events from Google Calendar, CalDAV servers, and ICS feeds into a single month view — with Chinese lunar calendar, solar terms, and public holiday annotations.

Features

  • Unified month view — see all your calendar sources in one place, color-coded by source
  • Google Calendar sync — OAuth 2.0 PKCE flow, no server required; supports multiple calendars per account
  • CalDAV sync — connect to Nextcloud, iCloud, Fastmail, or any CalDAV-compatible server
  • ICS feed sync — subscribe to any public or private .ics URL
  • Chinese lunar calendar — lunar dates, traditional festivals (春节, 端午, 中秋…), and 24 solar terms displayed in each cell
  • Public holiday overlay — statutory holidays and adjusted workdays (补班) sourced from holiday-cn
  • Event deduplication — events shared across sources are shown once, with configurable source priority
  • Auto-sync — configurable sync interval (default 30 minutes); manual sync available via command palette
  • Mobile compatible — works on iOS and Android (isDesktopOnly: false)

Privacy

UniCalendar operates entirely locally. Calendar credentials are stored in your vault's plugin data file (<Vault>/.obsidian/plugins/uni-calendar/data.json). No data is sent to any third-party service other than the calendar providers you explicitly configure. Holiday data is fetched from the jsdelivr CDN on first load and cached locally.
