A straight answer about the sky.
Zodiacs.org is a free astrology reference built on one idea: the astronomy can be exact even when the interpretation is a tradition. Every chart here is computed from the real positions of the planets, explained in plain language, and kept on your own device.
Why it exists
Most astrology sites are either beautiful and vague or accurate and unreadable. The calculators that get the math right tend to look like tax software; the ones that feel good tend to hand-wave the numbers. We wanted a third option — a place where you can get your full birth chart in about twenty seconds, see the exact degrees behind every claim, and read what they mean in ordinary words.
The reading comes first. Exact degrees, dated sky facts, and sources stay close by for anyone who wants to check them, without turning every page into a technical report.
Accuracy without the homework
When a date, degree, or birth time matters, it is calculated against the actual sky and checked before it appears. If you want the ephemeris, house systems, historical time-zone handling, and accuracy limits, the full methodology is public.
Your data stays yours
The engine runs in your browser, so the birth date, time, and place you enter are never sent to us. Charts you save live on your device unless you choose to sync them with a free account. There are no ads and no cross-site tracking. The full detail is on the privacy page.
Two registers under one roof
Most of the site is the astrology reference — guides, calculators, horoscopes, and the birthday pages. Alongside it lives the Registry, the collector's wing: a museum-toned catalogue of the twelve as a set of canonical records, kept in its own voice. The two share one design but keep their own registers; the astrology surfaces stay free of any market language, by design.
Astrofolio is a related but separate consumer experience; Zodiacs.org remains the astrology reference and the official Registry and SDK source.
Charts you save start on this device and sync only if you choose a Zodiacs.org account. Astrofolio separately explores personal Zodiac shelves, profiles, and share cards. It is never required to use the free tools.
The Registry’s operator and economic-interest attestations, the twelve dated origin receipts, and the establishment provenance are published on the disclosure page. Read the Registry disclosure.
How Zodiacs.org is maintained
Zodiacs.org is an independent project maintained by automated systems, without a traditional human editorial staff. Articles use the Zodiacs.org organizational byline; there is no invented editor, biography, or set of credentials behind it. The calculators remain free because the core math runs on your device.
Open the publication detailsAutomation, checks, and public records
AI agents can propose writing, design, and code, but free-form model prose cannot publish itself. Daily editions begin with structured sky facts and versioned local templates. A separate astronomy audit recalculates the sky, while policy checks reject unsupported facts, unsafe certainty, and incomplete editions before publication.
The current daily edition exposes its facts, generation mode, policy version, hashes, and verification result in a public publication record. The rulebook is machine-readable, the daily method is documented, and the correction log records material changes.
