Synastry and Relationship Astrology
No relationship technique can replace consent, observed conduct, communication, safety assessment, or the absent person’s privacy. Scope is explicit.
Overview
A Sun–B Moon conjunction is 2°; B Saturn is audited separately before any relationship synthesis. This is the worked result for Synastry and Relationship Astrology; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Begin with two intact natal charts, preserve A-to-B direction, audit data quality, and move to a constructed relationship chart only after naming its formula.

Synastry Overview and Reading Method
Synastry compares two intact natal charts through directional interaspects and reciprocal house overlays. Scope is explicit.
Read definition - relationship comparison · Synastry House Overlays
Synastry House Overlays
A house overlay asks which house of one person receives a planet from the other; reversing chart order changes the statement. Scope is explicit.

Composite Chart
A midpoint composite constructs one relationship chart from the shortest-arc midpoints of two sets of natal positions. Scope is explicit.

Davison Relationship Chart
A Davison chart derives a date, time, and place midway between two birth records, then calculates an ephemeris chart for that derived event. Scope is explicit.

Compatibility Score Limitations
No scalar can certify love, safety, consent, marriage, or breakup; use a score only as a transparent navigation aid. Scope is explicit.

Synastry with an Unknown or Approximate Birth Time
A noon chart is a convenience scenario, not a recovered birth time; it cannot justify exact angles, houses, or a confident Moon contact. Scope is explicit.

Definition and exact scope
Fourteen guides distinguish directional synastry, overlays, midpoint and Davison constructions, planet-specific contacts, score limits, and uncertain birth time.
Calculation or decision rule
Begin with two intact natal charts, preserve A-to-B direction, audit data quality, and move to a constructed relationship chart only after naming its formula. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Worked case and illustrative near miss
chart A ☉ 14°♉; chart B ☽ 16°♉ and ♄ 15°♒; major-aspect orb table attached. A Sun–B Moon conjunction is 2°; B Saturn is audited separately before any relationship synthesis.
Illustrative near miss; does not qualify: Turning one 2° conjunction into a verdict about the whole relationship while ignoring both natal charts.
School, model, and context variants
No relationship technique can replace consent, observed conduct, communication, safety assessment, or the absent person’s privacy.
Product, safety, and verification boundary
OpenFate connects Synastry and Relationship Astrology only to the two-chart compatibility flow and natal evidence; it does not score destiny or guarantee a relationship result. Synastry and Relationship Astrology preserves contrary observations and uncertainty. It cannot replace consent, professional help, location research, or a person’s account.
