Etar (from Arabic: إِيتَار) is an open source material designed calendar made for everyone!

The application is an enhanced version of AOSP Calendar. It provides:

- Month view.

- Week, day and agenda view.

- Uses Android calendar storage to show all synchronized calendars.

- Material Design.

- Dark and light theme.

- Support offline calendar.

- Agenda widget.

- Support sharing calendars via ICS and the ability to import/export from SD card.

- Multilingual UI.

## How to use Etar

Store your calendar on the phone only: Create an offline calendar.

Sync your calendar to a server: A cloud-synched calendar could be a google calendar, but you can also use any other public Caldav-server or even host your own (which would be the only way to keep full control over your data and still have ONE calendar usable from different devices.) To sync such a calendar to some server you need yet another app, e. g. DAVx5. That’s necessary because a Caldav client isn't included in Etar.

On Android there are "Calendar providers". These can be calendars that are synchronized with a cloud service or local calendars. Basically any app could provide a calendar. Those "provided" calendars can be used by Etar.

## Notes

Etar can import ICS files, for instance, received in invitation emails. The import feature is unstable and has a list of known bugs. Use it with caution, especially, if your calendar provider automatically sends out invitation emails.
