About AstroAxis
A free set of astrology and numerology calculators, built and kept running by one independent developer.
What AstroAxis is
AstroAxis is a set of free astrology and numerology calculators. For astrology there is the natal chart, synastry for a couple, business synastry for work partners and a page with today's sky. For numerology, your numbers profile, the Pythagorean square and the Destiny Matrix. Around them sit reference pages: planets in signs, sign pairs, the 22 arcana, Life Path numbers. All of it works without an account, in six languages.
Where the numbers come from
Planet positions and house cusps are computed on our server with Swiss Ephemeris, the astronomical library developed by Astrodienst. The birth time you enter is converted to universal time using the time zone rules your town had that year, daylight saving included if it was in force. The town's coordinates fill in by themselves when you pick it from the list. There are ten house systems to choose from; Placidus is the default. Numerology needs no server at all: the numbers are counted in your browser from the date and name you type.
About the AI readings
The AI doesn't calculate anything here. It receives the chart or the numbers already worked out — signs, degrees, houses, aspects — and writes a reading from them in the language the site is open in, so it can't make up where a planet stood. If you'd rather use your own assistant, every calculator lets you copy the same data as a ready prompt for ChatGPT, Gemini or any other chat. Each reading costs us money, so one visitor can only ask for a limited number of them within a few minutes.
Who is behind it
AstroAxis is built and maintained by an independent developer. There are no ads on the site and no paid version you'll be nudged towards. If something on a page looks wrong, the link in the footer of every page opens an email with that page's address already filled in.
