A relationship match lays two charts over each other and looks at what arises between them. Some channels only complete as a pair — that is what you can do together and neither of you can alone. Some centres you have open are filled by the other person: that is why one person leaves you calmer and another keyed up. No grade or compatibility percentage comes out of it, only a description of what happens between you. It works for children, parents and colleagues too.
Start with your own profile — once calculated, the partner match (synastry of two people) and the ancestral section where you add a partner and children unlock below the result.
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.
