Rainlendar Lite 2.15.4 (64-bit)Description by the Software Developer:
"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.
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.
You can also have a separate list for your long term tasks. The task list can be arranged several ways so that you can keep it better organized. You can also set a due date for the tasks to make sure you'll remember to do them on time.
You'll also get an alarm when an event or task is due so that you don't miss it. The alarm can be defined to be set off any duration before the actual event so you have time to prepare for it."
