Zodiac compatibility, or synastry, is the branch of astrology devoted to comparing two natal charts. It does not stop at comparing two sun signs but studies the positions and mutual aspects of two people's planets to bring out the harmonies and tensions of their relationship. This astrological comparison tool sets the key elements of each chart side by side, from a romantic, friendship, or professional angle. It belongs to a tradition of relational analysis attested since Hellenistic antiquity.
Zodiac compatibility, more rigorously called synastry, refers to the comparison of two astral charts to study the dynamic of a relationship. It examines the aspects formed between the planets of chart A and those of chart B: conjunctions, oppositions, squares, trines, and sextiles. The practice is documented as early as Greco-Roman antiquity and was codified during the Renaissance by astrologers such as Jean-Baptiste Morin de Villefranche (1583-1656). In the 20th century, the American astrologer Lois Rodden helped popularize the modern use of synastry in couple analysis.
For a precise synastry, enter the date, time, and place of birth of each of the two people. The time and place are needed to compute ascendants, houses, and the exact positions of the fast planets, all essential to any serious relational comparison. Without the time, the analysis remains possible but limited to the slower planets. Our tool crosses the charts of both people, highlights the major aspects between their respective planets, and flags areas of complementarity as well as the likely friction points, following the conventions of Western astrology.
Avoid reducing compatibility to a simple sun-sign comparison: that is the most common mistake. Examine first the contacts between Moon, Venus, and Mars, the planets of affect, desire, and attachment. Take into account each person's ascendant, which describes the mode of contact. Remember that an astrological tension is not an absolute incompatibility: it describes a dynamic to work with. Synastry is a symbolic grid, never a verdict.
Of course. The notion of "incompatible" signs is a popular simplification. In practice, a relationship is analyzed from the entirety of both charts: an Aries-Cancer pair, reputed difficult, can work very well if the Moons or Venuses are harmonious. Synastry significantly nuances generalizations.
Trines (120°) and sextiles (60°) are considered harmonious: they ease circulation between the two charts. Conjunctions (0°) reinforce a shared theme. Oppositions (180°) and squares (90°) introduce tensions, sometimes fruitful, sometimes draining depending on the planets involved.
No. Synastry applies to any relationship: friendly, family, professional, or cooperative. Astrologers use it, for example, to analyze business partnerships, creative duos, or parent-child relationships. The indicators analyzed differ depending on the type of bond studied.
The composite chart is a single chart built from the midpoints between the planets of two people. Theorized by the American astrologer Robert Hand in the 1970s, it describes the relationship itself as an entity, complementing synastry, which compares the two individual charts.
