Summary of Chart Types

An astrological chart is a radial diagram of the positions of celestial bodies, generally in geocentric relation to a specific place and time. Each type of chart denotes the disposition of cosmic influences uniquely & for various purposes.


Natal || The natal chart is the primary & fundamental astrological chart, calculated for each individual at their exact moment of birth. It is a permanent representation of one’s psyche & entire being; it indicates essence, personality, behavior, potential, lifestyle, upbringing, & the state of the soul in a broad yet detailed context. It is a tool for self-discovery, growth, & personal progress.

Transits || The word transit refers to the perpetual motion of a celestial body through multiple astrological measures of energy, particularly the Zodiac and the twelve houses. Transits affect everyone all the time, but uniquely per individual natal chart. They indicate general patterns, possibilities, changes, moods, and can even be used to loosely predict future events.

Return || A return takes place when a planet makes a full revolution through the Zodiac back to its natal position. The chart is calculated for the transits of the time when the return is exact. Solar & lunar returns are the most important. They indicate the perpetually evolving nature & personal growth patterns of the psyche, as well as one’s temporary disposition, life path, and problems.

Persona || There is a persona chart for each of the planets; the natal chart can be considered the sun’s persona chart (and it is the most important & most influential). Persona charts are calculated for the moment the sun passed through each other planet’s position. They indicate deeper energies & functions of the planets, further expanding the meaning of the natal chart.

Progressed || The progressed chart is a prognostic method that follows a unique day-to-year calculation; each of an individual’s present years is equal to one progressed day (e.g. the progressed chart for a 26-year-old person would essentially be the transits for 26 days after their birth). It indicates one’s growth & evolution as a person in a general sense & how they process experiences.

Harmonic || There are theoretically an infinite number of different harmonic charts, but the premise is that there is a harmonic for each aspect. The natal chart is divided by the number that creates an aspect’s angle, compressed, and then re-expanded to form a regular 360 degree chart. It reveals abstruse details about the theme/subject related to the original number’s symbolism.

Draconic || The Draconic chart is calculated by dialing a person’s natal placements back through the Zodiac until the North Node is at zero degrees in Aries. This chart is labelled the “soul chart” & is meant to represent a person’s purest or highest evolution of self, or some say it’s supposedly the natal chart they had in their previous incarnation. It is used relatively infrequently.

Midpoints || The points that lie directly between two celestial bodies (called “midpoints”) are considered to be very sensitive, receptive areas. Calculating midpoints adds another dimension or volume of archetypal/energetic meaning to the natal chart (or whatever other chart they are brought into). They must be activated by transits, synastry, or natal aspects in order to be relevant.

Uranian || Uranian astrology is a relatively new branch of the subject, less than a century old, which uses midpoints as its primary indicator of energetic or archetypal manifestation. It is considered a more complicated & more detailed yet somewhat unreliable/unfounded method of calculating charts (mainly natal charts), and it is not widely practiced as far as I can tell.

Composite || Composition is a method of relational astrology that uses the midpoints between all of the placements in two individuals’ natal charts to illustrate the nature, essence, disposition, inclinations, tendencies, potential, and general traits of their relationship. As the combination of what represents two different people, it can also indicate a lot about things they create together.

Davison || The Davison chart is another method of relational astrology that uses midpoints, but unlike the composite chart, it uses the date, time, and location that lies directly between the birth of two individuals’. It is essentially the “natal chart of the relationship.” It primarily indicates the organic basis of the relationship & its highest, most profound possible benefit for both parties.

Synastry || Synastry is the comparison of two natal charts by overlaying one upon the other. The Zodiac is the foundation of synastry; the positions of each individuals’ planets & houses are placed upon it simultaneously. This indicates every detail of their relationship, the entire exchange of energy between them, nearly every possible quality, flaw, problem, & benefit of their connection.
