Eortologio is an application for storing repeatable events like holidays, name days, world days etc. Some of the world days are already added, but because this application can be downloaded by anyone from any country with different culture I didn't add anything else.
This application is distributed as "freeware", without any time restrictions and does not contain spyware.
Also upon installation, the application does not add any registry entries and installs files only to the directory of your choice. A program group is created in Start Menu, a shortcut to your desktop and a shortcut to Startup folder for the application to lunch when windows start. If you do not want this to happen you can delete this shortcut from Startup Folder at anytime.
