An astrolabe was a real instrument — a brass disc with a rotating map of the sky, used for more than a thousand years by astronomers in Greece, in the Arab world and in medieval Europe. Nothing was prophesied with it. They sighted the Sun or a star, read off the angle, and the instrument told them the time, where they stood and when the Sun would rise. It was a tool for finding your position, not for foretelling your fate.
This place does the same with the moment you were born. It takes the date, time and place, computes where the planets stood at that instant, and shows you what sixteen traditions read from it — Human Design, astrology, Vedic astrology, the I Ching, chakras, numerology and more. Nothing is foretold, and no sentence here was written by an artificial intelligence: behind each one stands a number you can check for yourself.

Frequently Asked Questions
Yes — entirely and permanently, with no registration and nothing locked away. It exists to help.
No. The calculation runs without a database; the only memory of a result is the unique URL in your browser. The exception: a voluntarily entered e-mail (for results or the daily digest) is stored with the birth data it needs.
Planetary positions come from the astronomy-engine library (~0.003° accuracy); the Human Design engine exactly reproduces Ra Uru Hu’s published chart and the design chart uses the exact 88° of solar arc. The full methodology is published in Sources & Methodology.
We use 12:00 and the result flags time-sensitive values (ascendant, profile) where the exact minute matters. Your Human Design type is usually stable even with an approximate time.
A synthesis of the I Ching, astrology, Kabbalah and the chakra system: your birth date, time and place produce a bodygraph — a map of your energy with a type, strategy and inner decision-making authority.
Yes — Relationship Match works for partners, children, parents and colleagues, including a two-page narrative synastry. Children can get their own full chart too.
The address in your browser carries the whole input, partner and children included — just copy it. You can also save profiles locally in your browser and download the result as a PDF.
The ascendant changes roughly every two hours and near a cusp the exact birth minute decides; tropical vs. sidereal zodiacs differ too. Our card warns you when you sit on a sign boundary.
