The "Astronomical Almanac" calculates the exact position of the celestial bodies of the solar system, their rise, set and detailed characteristics.
The Astronomical Almanac application calculates the exact position of objects in the solar system, their sunrise and sunset for a given time and place. The time of the onset of the lunar phases and lunar days is also calculated.
To improve the accuracy of determining the location of the observer, geographical maps are used.
Calculations are made in the date range from 3000 BC. until 3000 A.D.
The program uses the Steve Moshier algorithms.
Designed for astronomical observations.
The following parameters are calculated for celestial objects:
- UT, TDT, Julian Day
- Sideral time, Delta T
- Radius vector
- Geocentric distance
- Elongation from the Sun
- Right ascension
- J2000, Right Climb
- J2000 Declination
- B1950, right ascension
- B1950 Declination
- Right ascension
- Equatorial diameter
- Visible value
- time of light
- Visible time

Ratings and Reviews
neglects the UI guidelines
Good idea for a program. Too bad it is so sloppily design. It doesn't respect the platform. For example, the "About" part is not in the menu as it should be. There is no Edit menu, meaning you can't copy the displayed text. No file menu either: you are not expected to want to export anything. I will not even mention the "Menu" string in the window, which is what? a menu? with a single item? Why not a button then? In short, the user experience is a disaster.
