Etar Calendar

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

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 ofFree Software for Android team,this app would be just a dream. So thanks to them!

Features

• Month view.
• Week, day & agenda view.
• Uses Android calendar sync. Works with Google Calendar, Exchange, etc.
• Material designed.
• Support offline calendar.
• Agenda widget.
• 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 useany other public Caldav-server or even host your own (which would be theonly way to keep full control over your data and still have ONE calendarusable from different devices.) To sync such a calendar to some server youneed yet another app, e. g. DAVx5. That’s necessary because a Caldav clientisn't included in Etar.

The following link provides a tutorial how to use Nextcloud + DAVx5 + Etar.

Technical explanation

On Android there are "Calendar providers". These can be calendars that aresynchronized with a cloud service or local calendars. Basically any appcould 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 addingan 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
