Rainlendar Lite 2.5 Build 80 Beta / 2.5 Build 72 is considered as a useful calendar tool that is easy to use and doesn't use much system resources or take much space on your desktop. 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.
All the coming events are shown in a separate list where you can see the weeks 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 youll 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.
