Etar Calendar is an open-source, Material Design calendar application for Android, built as an enhanced fork of the AOSP Calendar. It supports month, week, day, and agenda views, offline calendars, and works with any calendar provider synced to the device.

Use cases

• manage calendar events on android without google apps
• use an offline calendar stored only on my phone
• view month week day and agenda views in a material design calendar
• import and export calendars via ics files
• sync my calendar to a self-hosted caldav server
• use a privacy-friendly open source calendar app from f-droid
• add an agenda widget to my android home screen

When to choose

• you want a free, open-source, privacy-respecting Android calendar
• you need offline calendars or sync via third-party CalDAV clients like DAVx5
• you want a Material Design calendar with dark/light themes and multilingual UI
• you want to contribute to or customize your calendar app

When to avoid

• you need built-in CalDAV or Google Calendar sync without a separate sync app
• you rely heavily on stable ICS import, which has known bugs
• you need a calendar for iOS, desktop, or web platforms
