About Natal Points
A small set of free astrology calculators that get the astronomy right and explain how they reach each answer.
What you will find here

How the pages are made
The numbers come from a calculation engine, never from memory or from a writer's guess. It is built on Astronomy Engine, an open-source library, and tested against data from NASA's Jet Propulsion Laboratory. The method page shows those tests.
The written explanations are drafted with the help of an AI assistant, then read, checked and edited by our editor before they are published. The editorial policy sets out the rules we hold them to.
Where we stand on astrology
Astrology is a tradition of interpretation that people use for reflection. The positions of the planets are facts, and we work to get those exactly right. What a position means is a matter of tradition, and we say so when we describe it. Nothing here is advice about your health, money or legal affairs.
