Rainlendar is a feature rich calendar application that is easy to use and doesn't take much space on your desktop. The application is platform independent so you can run it both on Windows and on Linux. The appearance can be customized with skins and you can even mix different skins together.
 
It is possible to use Rainlendar with other calendar applications too. Rainlendar uses the standard iCalendar format to store its events and tasks so you can easily transfer them between applications. You can also subscribe to online calendars and see your Outlook appointments directly in Rainlendar*.
 
Rainlendar is an unicode application and support localization so you can use it on your own language.
