Productivity - Desktop Calendars (8)

UK's Kalender is a personal calendar that sits in the system tray and reminds you of upcoming events or deadlines. Events can be displayed in weekly, fortnightly, monthly or yearly view. They can also be organized into different categories with their own settings. Documents or programs can be attached to an event so that they are automatically launched when the event fires. The program also allows sharing via network (multi-user).

Rainlendar is a skinnable, easy-to-use calendar that resides on your desktop and shows the days of the current month. You can add events and tasks with customizable icons and formats to the calendar and be reminded when they occur. Rainlendar uses the standard iCalendar format to store its events and tasks so you can easily transfer them between applications.

Cross-platform (Windows, Linux, OS X).

Note: Rainlendar Lite is the freeware version of Rainlendar Pro (Payware). The lite version is missing network shared calendars, Outlook support and other features.
