Human Design Bodygraph — Type & Authority
Your Human Design Type, Authority, and defined Centers, computed from real Personality (birth-moment) and Design (~88 days prior, based on the Sun's real solar-degree offset) planetary activations — genuine chart math, not a generic type quiz.
The Design activation uses the Sun's real position roughly 88 solar degrees before your birth — not a fixed 88 days, since the Sun's apparent speed varies slightly through the year — computed precisely rather than approximated, which is what actually determines your unconscious Design Sun and the rest of your Design-side activations.
Frequently Asked Questions
What is the 'Design' date in Human Design?
It's the moment roughly 88 degrees of solar arc before your birth — about three months earlier — not a fixed number of days. This tool finds that exact moment by real solar-arc root-finding, rather than an approximate '88 days before' shortcut some sources use.
What are the five Human Design Types?
Manifestor, Generator, Manifesting Generator, Projector, and Reflector — determined by which of the nine Centers are defined and how they connect, not chosen directly.
What does 'Authority' mean in Human Design?
It's the decision-making center Human Design recommends trusting first — for example Sacral, Emotional (Solar Plexus), or Splenic authority — derived from which Centers are defined and in what priority order.
Is Human Design based on astrology?
Partly — it combines real planetary positions (astrology) with the I Ching's 64 hexagrams, the Kabbalistic Tree of Life, and chakra theory, synthesized by Ra Uru Hu in 1987. It's a modern system, not an ancient one.
Do I need my exact birth time for Human Design?
Yes — both your Personality and Design activations depend on precise planetary longitudes at specific moments, and Gate/Line placement is sensitive enough that an inaccurate birth time can shift results.
