There are a lot of astrology programs out there. Most are written for Windows only. The exceptions are Astrolog (Macintosh and UNIX versions), Io Series by Matrix Software(Mac), and TimePassages (Mac). Some programs are better than others, but it shouldn't be difficult for you to find one that does what you need, is user-friendly, and fits your budget.

In many cases, these software companies produce other programs in addition to their Western astrology offerings. These include Tarot, biorhythms, and Tibetan astrology.

Jyotish (also called Vedic or Hindu astrology) is growing in popularity. I've listed the sites for the two leading Jyotish programs below.

I've commented on the software I've used; I welcome your comments on the ones I'm unfamiliar with. If you have suggestions for software information or websites to be added to this page, please e-mail me.

• Astrolog
  This was the first Windows astrology program I used back in the 1990s, mainly because it was FREE, but also because it was good. Astrolog is still freeware, and is currently available in Windows, DOS, Macintosh, and UNIX versions. The source code is also available for you astro-geeks out there. ;-) The program has been around since 1991 (the current version is 5.40), and has won numerous awards; the original developer, Walter Pullen, continues to maintain and develop it. It's amazing what this little program (606K in the Windows version) can do!

  One of the two leading Jyotish (Hindu astrology) computer programs. Available for Windows and Macintosh.

• Solar Fire
  This Australian astrology program for Windows is one of the most popular in the world. When I decided to buy a professional-level program, I bought Solar Fire because it did everything I wanted, yet was extremely easy to use. It's available in the US from Astrolabe and Sagittarius Books/Astrology-Books.com, among others.
