I just saw this from GNOME Recent Changes, and I couldn’t find much more details about it. It seems that Jim Nelson from Yorba is working on a new calendar application for GNOME 3. Judging from the previous projects of Yorba (Geary, Shotwell) we should expect something good coming!

Above is the Gnome-Calendar App. It looks great, but it also seems a little bit forgotten..

Gnome-Calendar

This is California Calendar. It requires GTK 3.12 (for popovers) and currently isn’t a really working application. It uses EDS (Evolution Data Server) and it is written in Vala.

Planned Features

Modern, clean interface

Quick setup (if any is required at all)

Uses EDS for calendar access, potentially other specialized backends (i.e. GData)

Desktop notification of events

Copyrights go to Yorba Foundation, but California so far is a personal job of Jim, at least according to Git-logs. First commit made this January, so it is a pretty new application and under heavy development.

Both applications above are built today from upstream against GNOME 3.12
