What an energy type chart is
The chart is a diagram of nine centers connected by channels, built from your date, time and place of birth. Five things are read from it: the type, its strategy, the authority (how to make decisions), the profile and the definition (how the defined centers connect to each other). The system appeared in 1987. Its author described its origin as a mystical experience, and in structure it stitches together several traditions: Western astrology for planet positions, the 64 hexagrams of the Chinese Book of Changes, Kabbalah and Vedic philosophy. Reference sources openly classify it as pseudoscientific, and we agree: it is a language for self-observation, not a diagnosis and not a forecast. Unlike a horoscope, it has no signs as personalities and no houses. The only astronomy in the chart is where the Sun, the Moon and the planets stood at two specific moments. Everything else, from the name of your type to the meaning of a channel, is the system's own rulebook.
Two moments: birth and the prenatal moment
The chart is built from two moments rather than one. The first is birth itself. Body positions at that moment give a set of activations that the system links to what a person is aware of in themselves. The second moment comes before birth: when the Sun stood exactly 88° of the ecliptic behind its birth position. We call it the prenatal moment. The Sun moves about a degree a day, but unevenly: faster in early January, slower in early July. So 88° does not equal 88 days; it takes anywhere from 86 to 92 days. The correct method finds that moment from the Sun's actual position rather than by counting calendar days. The system links this second set of activations to what a person does not notice in themselves but others can see. An example: for a birth on 15 May 1990 at 14:30 Moscow time, our calculation puts the prenatal moment at 07:06 UTC on 15 February 1990, which is 89.1 days before birth.
Gates, lines and the 26 activations
The system splits the ecliptic circle into 64 sectors called gates. Each gate spans 5.625°, and the gate numbers match the numbers of the hexagrams in the Book of Changes. The numbering is not sequential: the wheel starts with gate 41 at 302° of ecliptic longitude (2° Aquarius) and continues in a fixed order. Each gate is divided into 6 lines of 0.9375°. At each of the two moments, 13 points are taken: • the Sun and the Earth (the point opposite the Sun); • the Moon; • the north and south lunar nodes; • Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. 13 points at two moments give 26 activations. Each is written as gate and line: 23.6 means gate 23, line 6. The zodiac here is tropical, the same one a Western natal chart uses. So the accuracy of the whole diagram rests on two things: the ephemeris and your birth time.
Centers and channels
The diagram has nine centers: Head, Ajna, Throat, G (the Self center), Heart (Ego), Spleen, Solar Plexus, Sacral and Root. Every gate belongs to exactly one center. 36 channels run between the centers. A channel has a gate at each end. If both gates are activated, at either moment and in any combination, the channel is defined, and so are the two centers it connects. A center with no defined channel stays open, even if a single gate inside it is active. The system calls four centers motors: Sacral, Heart, Solar Plexus and Root. Which motors are defined, and whether any of them reaches the Throat, decides the type. Defined centers can form one connected chain or several separate islands. That is the definition: single, split, triple split or quadruple split. A Reflector has no definition at all.
The five types and how they are calculated
A type is not picked from a description; it is derived by rules: • Reflector: all nine centers are open. • Generator: the Sacral is defined, but no motor connects to the Throat. • Manifesting Generator: the Sacral is defined and some motor connects to the Throat through a chain of channels. • Manifestor: the Sacral is open, and the Heart, Solar Plexus or Root reaches the Throat. • Projector: the Sacral is open and no motor connects to the Throat. We computed 2,000 random birth moments between 1950 and 2005. The result: Generators 36.9%, Manifesting Generators 32.8%, Projectors 22.4%, Manifestors 7%, Reflectors 1.1%. So nearly seven people in ten have a defined Sacral (36.9 + 32.8 = 69.7%). Each type gets a strategy, a short rule of conduct: Generators are told to respond, Manifesting Generators to respond and then inform, Manifestors to inform before acting, Projectors to wait for the invitation, Reflectors to wait a lunar cycle before big decisions. Each also has a signal that life is going off track: frustration for Generators, anger for Manifestors, bitterness for Projectors, disappointment for Reflectors.
Authority: how the system suggests making decisions
Authority follows a hierarchy of centers. The first defined center on this list wins: • Solar Plexus: emotional authority, deciding once the emotional wave has passed; • Sacral: sacral authority, a gut yes or no in the moment; • Spleen: splenic authority, a quiet instant hunch; • Heart: ego authority, manifested if the Heart reaches the Throat, projected if it only connects to the G center; • G center linked to the Throat: self-projected, talking a decision through out loud; • only Head, Ajna and Throat defined: outer (mental) authority, discussing it with people you trust; • Reflector: lunar authority, about 29 days. Because the Solar Plexus comes first, emotional authority is the most common. In our computation it belongs to 43.8% of Generators, 57.4% of Manifesting Generators, 42.5% of Projectors and 66.2% of Manifestors, and to about 49% of people overall.
The profile: 12 combinations, six of them rare
A profile is two numbers: the line of the Sun at birth and the line of the Sun at the prenatal moment. Profile 6/2, for example, means the Sun stood on line 6 of its gate at birth and on line 2 at the prenatal moment. The lines have names: 1 Investigator, 2 Hermit, 3 Martyr (learning by trial and error), 4 Opportunist (connections and a circle of acquaintances), 5 Heretic (other people's expectations and projections), 6 Role Model. There are only 12 combinations, and they are far from equally common. In our computation six profiles are frequent: 6/2 (15.4%), 3/5 (15%), 2/4 (14.1%), 5/1 (14%), 1/3 (13.7%), 4/6 (13.5%). The other six are rare, from 2.1% to 3%: 5/2, 2/5, 3/6, 4/1, 6/3, 1/4. The reason is pure geometry. The arc of 88° equals 93.87 lines, so the two Sun lines are tied by an almost fixed offset. If the birth Sun sits anywhere in the first 86.6% of its line, the prenatal line lands two steps further around the circle of six: 6 gives 2, 3 gives 5, 4 gives 6. Only when the birth Sun is in the last 13.4% of its line does the offset become three steps, which produces the rare profiles. Theory gives 13.4% for all rare profiles combined; our sample of 2,000 dates gives 14.7%, within random sampling error.
One chart from start to finish
Take a birth on 15 May 1990 at 14:30 Moscow time (10:30 UTC). The Sun at birth is in gate 23, line 6; at the prenatal moment (15 February 1990) it is in gate 30, line 2. That gives profile 6/2. Four channels are defined: 13-33, 23-43, 24-61 and 30-41. They join the Head, Ajna, Throat and G center into one area, and the Solar Plexus and Root into another. Two separate areas make a split definition. The Sacral is open. Two motors are defined, the Solar Plexus and the Root, but neither reaches the Throat. By the rules this is a Projector. The Solar Plexus is defined, so the authority is emotional. The result: Projector, emotional authority, profile 6/2, split definition. The type chart calculator gives the same answer for this birth and lists all 26 activations with their degrees.
Why the exact birth time matters
The Moon moves fastest, about 13° a day. It crosses a gate in roughly 10 hours and a line in about 1 hour 40 minutes. The Sun is slower: a line takes it almost a day (about 23 hours), a gate almost 6 days. The Moon decides gates, and through them channels, centers and the type. The Sun decides the profile, and here the geometry above kicks in: if the birth Sun is in the last 13% of its line, the prenatal line shifts by one. In our example, moving the birth from 14:30 to 15:30 turns profile 6/2 into 6/3. That is why the calculator shows what changes if the time moves by 15 and 60 minutes in either direction. If you only know your time as "some time after lunch", check those shifts before trusting the profile. The time zone matters too: we convert local time to UTC with historical rules, including daylight saving time and zone changes. If your time is uncertain, this article on birth time explains how reliable different sources are.
Type chart versus natal chart: where science ends
Both charts come from the same ephemeris, then go separate ways. A natal chart has signs, houses, the Ascendant and aspects between planets. A type chart has no houses and no Ascendant, does not use signs as personalities, and puts gates and channels at the center. The honest line runs like this: • planet positions are calculated precisely with Swiss Ephemeris, the same engine as our natal chart; on 12 reference dates from 1879 to 2020 our calculation matched an independent one in 312 of 312 activations; • the meaning of gates, types and profiles is the system's interpretation, and neither astronomy nor psychology backs it; • a type is not a diagnosis or a verdict. It works best as a mirror: read the description and ask whether it sounds like you. If the description does not match your experience, trust the experience, not the diagram.
Frequently asked questions
Can it be calculated without a birth time? Only roughly, and the type and profile often stay unknown: the Moon crosses more than two gates in a day. Our calculator asks for the time and place. Which type is the rarest? The Reflector: 1.1% in our computation, about one person in ninety. Can my type change over time? No. It comes from two fixed moments, before and at birth. Only the accuracy changes if you pin down your birth time. Why do different sites give different results? Usually because of the time zone or an imprecise birth time. Less often because of how the prenatal moment is found: the correct method uses 88° of the Sun, not a count of 88 days.
