Huber Chart Calculator
Your birth chart with the Astrological Psychology method of Bruno & Louise Huber: the Koch house system, the colored aspect pattern (red–blue–green motivation colors), the Age Point (Life Clock) and the Low Point.
About the Huber Chart and Astrological Psychology
The Huber method (Astrological Psychology / API) is a distinctive school developed by the Swiss astrologer couple Bruno and Louise Huber, uniting psychology with astrology. It differs from the classical birth chart on three fundamental points: it uses the Koch house system, it groups aspects into three colors (red, blue, green) to form an "aspect figure" at the centre of the chart, and it applies the Age Point (Life Clock) technique for timing.
What does the colored aspect pattern show?
In the Huber school every aspect carries a "motivation color": red (conjunction, square, opposition) stands for will and action; blue (trine, sextile) for harmony and natural talent; green (semi-sextile 30°, quincunx 150°) for sensitivity and searching. The balance of these colors in the chart reveals the person's core life motivation. Orb values follow the conservative Huber tradition and are luminary-aware (slightly wider when the Sun or Moon is involved); they are a simplified adaptation of the planet-specific orb table found in the school's books.
What are the Age Point (Life Clock) and the Low Point?
The Age Point is a timing indicator that starts at the Ascendant at birth and moves on house by house. Each house takes 6 years; the whole wheel takes 72 years. The house the Age Point occupies, and the aspects it forms to natal planets, show the developmental theme of that period of life. The Low Point (Talpunkt) is the golden-ratio point of each house: planetary energy is outgoing and strong at the house cusp, inward and quiet at the Low Point. The tool marks the Low Point of every house on the wheel with small rings.
I don't know my birth time
Koch houses and the Age Point (Life Clock) depend entirely on the birth time; an error of 1 hour shifts the Ascendant by roughly 15°. If you don't know your time, tick "I don't know my birth time": the tool then shows only the time-independent planetary positions and the colored aspect pattern, hiding houses and the Age Point (as the Moon moves ~13° per day, its position stays uncertain by ±6–7°). The lasting solution is rectification: the classical technique of determining your birth time to the minute by working backwards from life events (moves, marriage, loss, career turns, births).

What does this tool calculate?
From your birth date, time and place it calculates the planetary positions (astronomy-engine ephemeris), the Koch house cusps (Swiss Ephemeris algorithm), the colored aspect pattern, notable aspect figures, the Age Point position and its aspects to natal planets, and the Low Point of every house. Results are for education and self-reflection.

Frequently Asked Questions
Is a Huber chart different from a normal birth chart?
The planetary positions are the same; the difference lies in the interpretive frame and the visualization. The Huber method uses Koch houses, the colored aspect figure and Age Point timing.
Why the Koch house system?
Bruno Huber preferred the Koch (Birthplace) system for its sensitivity to the place of birth (latitude). Koch houses are unequal, and this inequality matters for the aspect figure to emerge correctly. This tool computes the Koch cusps with the Swiss Ephemeris algorithm and draws them at their true (unequal) widths on the wheel. Above the polar circles Koch is undefined; the tool then falls back to Porphyry and says so explicitly.
How are the aspect colors assigned?
Red = conjunction/square/opposition (will), blue = trine/sextile (harmony), green = semi-sextile 30°/quincunx 150° (sensitivity). The color balance shows the person's core motivation.
How does the Age Point move?
It starts at the Ascendant and moves counter-clockwise house by house; each house takes 6 years, the full cycle 72 years, after which a second cycle begins. Because Koch houses are unequal it moves through the zodiac at a variable speed.
What is the Low Point (Talpunkt)?
The golden-ratio point (61.8%) of each house. In the Huber school planetary energy is most outgoing at the house cusp and most inward at the Low Point; the Age Point's Low Point crossings mark periods of turning inward.
What if I don't know my birth time?
Tick "I don't know my birth time"; the tool hides houses and the Age Point and shows only the planetary positions and the aspect pattern. For reliable houses and Ascendant your birth time needs to be established by rectification.
Are the modern planets included?
The Huber method also uses the modern planets (Uranus, Neptune, Pluto); the wheel always shows all 10 planets. By default only the classical seven enter the aspect pattern; an option lets you include the three modern planets as well.
Is this tool free?
Yes, completely free. For a deeper reading you can book a one-to-one consultation.
How reliable are the results?
Planetary positions come from a professional ephemeris (astronomy-engine) and the Koch houses from the Swiss Ephemeris algorithm. The interpretive frame rests on the established concepts of the Huber school.
