Calculation methodology
Planetary positions
Geocentric ecliptic longitudes are calculated in the browser with Astronomy Engine. Chiron and mean Black Moon Lilith use local orbital approximations.
Time and location
The selected city supplies an IANA time-zone identifier. Historical UTC offset and daylight-saving rules are resolved for the entered local date.
Houses and aspects
Placidus, Whole Sign, and Equal House systems are available. Major aspects use explicit orbs: conjunction/opposition 8°, square/trine 7°, sextile 5°.
Compatibility
The score is a reflective weighted summary of close cross-chart aspects and is not a scientific measure of a relationship.
