What is birth chart compatibility?

Birth chart compatibility compares two natal charts to understand relationship dynamics, emotional fit, attraction, communication, and long-term potential.

Is birth chart compatibility the same as synastry?

Usually yes. Birth chart compatibility is the broader phrase most people search for, while synastry is the technical astrology term for chart comparison.

What placements matter most for love compatibility?

Moon, Venus, Mars, Mercury, rising sign, house overlays, and the aspects between personal planets usually matter most.

Can incompatible charts still have a good relationship?

Yes. Difficult aspects do not automatically mean failure. They usually point to growth areas, pressure points, or habits that need more awareness.

Do I need both birth times for a compatibility reading?

If possible, yes. Exact birth times make the chart comparison much more accurate, especially for houses and rising signs. --- Relationship astrology is more useful when it is specific.
