 EfeCalc is a program to calculate ephemeris for the Sun, Moon, Planets and Stars. You can also calculate Solar and Lunar Eclipses and Time and Calendar Phenomena. This program has an extensive on-line help file, it generates graphics for some phenomena, it can be automatically updated and you can export the results to many different file formats. All of this free of charge!
Features include:
- Basic Sky Simulation: You can also see the bodies in the sky up to 5 different views: Equatorial,...
- Cities database: Over than 600 world cities;
- Stars Database: Almost 500 stars with parallax and proper motion;
- Extensive on-line Help File: These pages are intended to explain almost all that is needed to do the calculations. So besides get to know how to work with the program you can also learn all the theory behind!
- Export Results to different formats: HTML (web page), TXT (textfile) and CSV (excel spreadsheet).
Possible Calculations:
 Sun - Apparent Movement: Rise, Culmination and Set;- Coordinates: Ecliptics, Equatorials and Horizontals;- Solar Physics Parameters;- Diameter and Distance to the Earth;- Equation of Time (with auto-generated graphic for the month or the year).
 Moon - Apparent Movement: Rise, Culmination and Set;- Coordinates: Ecliptics, Equatorials and Horizontals;- Moon Phases, Perigee and Apogee;- Diameter, Distance to the Earth, Parallax, Iluminated Fraction and Age.
Eclipses - Lunar Eclipses;- Local Solar Eclipses;- Central Line for Solar Eclipses (with an auto-generated map showing the eclipse path over the Earth).
 Stars - FK5 Coordinates;- Mean Coordinates;- Apparent Coordinates;- Parallax, Distance to the Earth and Proper Motion.
 Planets - Apparent Movement: Rise, Culmination and Set;- Coordinates: Ecliptics, Equatorials and Horizontals;- Distance to the Earth and to the Sun, Apparent Diameter, Parallax, Iluminated Fraction and Magnitude.
 Time and Calendars - Julian Day;- Sideral Time and Dynamical Time;- Start of the Seasons;- Christian and Jewish Easter and Chinese New Year;- Entrance of the Sun into the Zodiac.
