Yorba team has introduced its calendar app ‘California’ two months ago. Now the first release California 0.1.0 (UNSTABLE) is available.

California is a new calendar application for GNOME 3. It’s currently under heavy development. It features:

Modern, clean interface
Quick setup (if any is required at all)
Uses EDS for calendar access, potentially other specialized backends
Quickly add events with natural-language parser
Desktop notification of events

If you’re using Google Calendar or web calendar (.ics), you can import them to California from its menu.

Install California:

NOTE: California is unstable and in active development at the moment. Use it at your own risk!

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run the commands below one by one to install it from Yorba’s daily build PPA:

sudo add-apt-repository ppa:yorba/daily-builds

sudo apt-get update

sudo apt-get install california

Because the PPA also contains development versions of Geary and Shotwell, you may remove the PPA after:

sudo add-apt-repository -r ppa:yorba/daily-builds

sudo apt-get update

Or, download the California calendar directly from the PPA page.

Looking for a calendar app? Besides Google Calendar, there’s a good choice for Ubuntu Linux users, called rainlendar, which a highly customizable desktop calendar that keeps your events and tasks and reminds your with alarms.

Rainlendar supports events and tasks which both are kept in separate lists.

You’ll get notified in advanced before the event is due so that you don’t forget your important events. It is also possible to snooze the alarm if you want to get reminded about it later.
