Frequently asked
Accuracy, privacy, and where the astronomy ends and interpretation begins — answered plainly.
How accurate are AstralMath calculations?+
Positions come from Swiss Ephemeris, the same high-precision ephemeris used in professional and research astronomy software, accurate to the arc-second across a date range from 13,000 BCE to 17,000 CE. We compile it to WebAssembly and run it unchanged — the astronomy is not approximated.
Is astrology real? What does the math actually say?+
We separate two things. The astronomy — where the planets were at your birth — is rigorous, measurable, and exact. The interpretation layered on top is a symbolic tradition, not a physical prediction. AstralMath is honest about that line: we give you exact astronomy and clearly-labelled interpretation, so you can judge for yourself instead of being sold certainty.
Do I need an account or to hand over my birth data?+
No. Every calculation runs in your browser via WebAssembly. Your birth date, time, and place never leave your device and are never sent to a server. There is no sign-up.
What makes this different from other astrology sites?+
Most sites hide a lookup table or a paid API behind a pretty chart. AstralMath is astronomy-first and open-source: the calculation engine is public, verifiable, and embeddable. We show the math instead of asking you to trust a percentage.
Which traditions do you support?+
Astronomy is universal; the systems built on it are cultural. AstralMath computes Vedic (sidereal) and Western (tropical) today, with Chinese BaZi in progress and Mayan and Arabic/Perso-Islamic systems planned — each by its own authentic rules, not a Westernized approximation.
Is AstralMath open source? Can I build on it?+
Yes. The core engine is open-source under a permissive license so you can read it, verify it, or embed it. An MCP (Model Context Protocol) server is planned so AI assistants can call the engine directly — making AstralMath the calculation layer behind AI-native astrology.
Still deciding? Just run it.
The fastest way to judge the accuracy is to compute your own chart and read the numbers.
