Synastry compatibility: what two birth charts really reveal
Zodiac-sign matches are a quick shorthand. Real synastry compares the exact planetary positions in two natal charts and shows how two people support, attract, challenge and change one another.
Sun-sign compatibility is only the beginning
Sun signs describe identity and direction, but they are only one part of a complete natal chart. Synastry compares the Sun, Moon, Mercury, Venus, Mars and slower planets in both charts.
What a synastry chart compares
A synastry chart measures conjunctions, sextiles, squares, trines, oppositions and quincunxes, their orbs, house overlays and contacts to the Ascendant and Midheaven.
Love, family, friendship and work
The same planetary contact has a different emphasis in different relationships. Zodigo applies separate calculations for romantic, family, friendship and professional compatibility.
Why exact birth time matters
Exact time determines the Ascendant, Midheaven and houses. Without it, planet-to-planet aspects remain available, but house overlays and angles cannot be treated as exact.
