base on Android open source calendar # Etar Calendar Etar (from Arabic: `إِيتَار`) is an open source material designed calendar made for everyone! [<img src="metadata/en_fdroid.png" height="60" alt="Get it on F-Droid">](https://f-droid.org/packages/ws.xsoh.etar/)[<img src="metadata/en_google_play.png" height="60" alt="Get it on Google Play">](https://play.google.com/store/apps/details?id=ws.xsoh.etar)  ## Why? Well, I wanted a simple, material designed and state of the art open source calendar that anyone can make better. ## Special thanks The application is an enhanced version of AOSP Calendar. Without the help of [Free Software for Android](https://github.com/Free-Software-for-Android/Standalone-Calendar) team, this app would be just a dream. So thanks to them! ## Features - 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. ### Technical explanation 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. You can even configure in Etar which ones are to be shown and when adding an event to which calendar it should be added. ### Important permissions Etar requires - READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE ->import and export ics calendar files - READ_CONTACTS(optional) Is queried the first time an appointment is created and can be rejected. But then search and location suggestions no longer work. ->allows search and location suggestions when adding guests to an event - READ_CALENDAR & WRITE_CALENDAR ->read and create calendar events ### Known issues with the ICS import feature Etar can import ICS files, for instance, received in invitation emails. The import feature is unstable and has a list of known bugs. Refer to https://github.com/Etar-Group/Etar-Calendar/pull/653 as a reference to those bugs. Use it with caution, especially, if your calendar provider automatically sends out invitation emails. ## Contribute ### Translations Interested in helping to translate Etar?
