 ZDNet
rates it 5 stars! "Looking for a well-done astronomical
clock program? Check out the Fourth Day..."
 The
Fourth Day™ is an astronomical
clock and almanac for your system tray (Windows 95 or later).
An accurate 3D simulation of the Earth as lit by the sun is
presented. Enter your latitude and longitude, or select from
over 23,000 database entries, and The Fourth Day™
will calculate the time of your sunrise and set, the start and
end of civil twilight, and your local noon (when the sun is
highest in the sky). Multiple user options allow for
customization of the earth display, and you can set your PC's
clock over the Internet using the master time server at
the US Naval Observatory. Astronomy buffs will appreciate the
real-time display of Julian Day, both local and Greenwich
sidereal time, and correct display of moon phases.
