Compatibility by two birth charts — synastry
Full synastry: Moon, Venus, Mars, aspects and houses of both partners. Free compatibility score online — full PDF reading after payment.
Sun-sign compatibility is only the opening line. The real picture comes from two complete natal charts: the Moon (emotions), Venus (love), Mars (drive), the ascendants, and the aspects that run between both people’s charts. That cross-reading is what astrologers call synastry.
Here is a compatibility calculator that takes two birth dates: a free score right away, and a detailed PDF reading after payment. It runs on the same engine that builds your individual natal charts.
