Almanac gives you the capability to determine the times of rising, setting, and meridian transit for the sun, the moon, and the planets. It also enables you to calculate the beginning and ending of astronomical, nautical, and civil twilight. The results of the calculations are formatted and written into a text editor. You can perform all common editing functions and save the data as a text file.
The formulae used in Almanac assume an ideal horizon where the intersection of the sky with the apparent plane of the earth's surface at the observer is the horizon. For rise/set calculations, the observer has zero elevation so that the horizon is exactly 90 degrees from the local vertical. Refraction of light passing through the earth's atmosphere tends to make objects appear higher in the sky than they actually are. This effect increases as an object's altitude decreases. Almanac assumes average atmospheric conditions in compensating for refraction. Lunar parallax changes the perceived altitude of the moon because the observer is not at the center of the earth. Parallax makes that the moon appears lower in the sky. Almanac compensates for this effect. Parallax for the Sun and planets is small enought to be ignored for this application.

Planet's Orbits (for Windows 98/ME/2000/XP) is an accurate digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (accurate for dates between 2000 B.C. and 6000 AD) for the calculation of planetary (except Pluto) and lunar positions. The calculation of the positions of the satellites of Jupiter, Saturn, and Uranus is done by the various analytic theories given in the Explanatory Supplement to the Astronomial Almanac (1992).The positions of the other objects (asteroids, comets) are calculated by it's osculating orbital elements. Therefore the positions of these objects are accurate only for a small period of time.The version 1.7. shows the positions and trajectories of various spacecrafts.The most noteworthy functions are date specification (past, future), 2D/3D orbital animation and custom zoom, orbits of 10000+ asteroids and comets from different databases, simple database handling and updates, printing, statistic, and information windows.

Winday is a fast, small calendar program developed for use in Windows
95/98/ME/NT/2000. In a single screen, this program gives the current
(system) date and time, and some information of interest for that day,
such as that encountered in an almanac. The information given (besides
time and date) includes: anniversaries, moon phase, sunrise and sunset;
if applicable for that day, religious observances, astronomical events
and special messages are indicated. A thought for the day is also
given. The user can also move to other dates, and see, for example,
future occurrences.
