ActiveEarth is a world time clock with a gorgeous day/night merge of NASA's Visible Earth satellite images in flat maps or a globe, with a row of user-definable clocks along the bottom. These clocks are beautiful, scalable, ticking, analog clocks that come in several styles with many custom settings. Each clock is set to a city of your choice. The program has accurate time zone data for more than 500, major world cities and you can add your own.

ActiveEarth is an indespensable time utility. A graphical time difference between two cities quickly answers the question, "Is this a good time to call my friend on the other side of the planet?" Along with the real time view of the day and night portions of the earth, ActiveEarth calculates astronomical data for each city; sunrise, sunset, moon rise and set, moon phase, etc. All of these things are beautifully, graphically displayed. You can set the program to display data for a specific time. ActiveEarth can even keep your PC's clock synchronized to an atomic time server.

You can track important future events with countdown clocks! ActiveEarth allows you to countdown to future astronomical events and to specify your own custom events. The program can play an alarm sound to help you remember a birthday or anniversary.

Finally, ActiveEarth comes with a screen saver that ties into the main program. Your favorite clocks or countdown events can be displayed with your favorite map view while your PC is idle.
