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.

All the coming events are shown in a separate list where you can see the week's events at one glance. You can decide how many days in advance you want to see in the list. Different events can have a different appearance in the list so you can easily spot the important events from the others. The icons in the calendar are also available in the event list and other windows to make it easier to separate the events.
