Day Planner and Calizo: Simple calendaring tools
If advanced calendar applications like Evolution and Sunbird are overkill for your needs, try Day Planner, a simple yet efficient calendaring utility. If you want to view your calendar as a timeline, check out Calizo instead.
Day Planner is not riddled with pointless tools and never-to-be-used features, which makes it a great choice for users striving toward distraction-free computing. Installation is easy. Day Planner's Web site contains packages for Debian/Ubuntu and Mandriva, as well as a generic installer for other Linux distributions. There is, of course, a source code archive for those who prefer to compile software on their machines.
Day Planner's interface is refreshingly simple, and you can start adding events right away. To do this, press the "+" button at the bottom of the window to open the Add an Event dialog window with the Date field set to the current date. Day Planner supports three types of events: Normal, All day, and Birthday.
