Pick two signs and we’ll tell you how their energies tend to fit. With an honest warning: sun signs are the cover — the whole book is each person’s full chart.
The serious comparison uses both complete charts: date, time and place for each of you.
Sun-sign compatibility rests on the elements: fire and air feed each other, earth and water nourish each other, and cross mixes ask for more translation. It’s a fine first glance — but two people are far more than their Suns: the Moon, Venus, Mars and the rising sign weigh as much or more in how you love and live together. That’s why our serious couple reading compares both full charts, degree by degree.
Comparing only Sun signs is fun but very partial. Real compatibility between two people shows in the synastry, which compares both full charts, not just the Sun.
By element there's usually good chemistry within the same element, and between fire and air or earth and water. But it's a general guide: it depends on the rest of the chart.
Sign compatibility looks at one piece, the Sun. Synastry crosses both full charts (Moon, Venus, Mars, rising signs, houses and aspects) and explains what unites you, where you clash and how to care for each other.
Yes, sign compatibility is free and needs no sign-up. The serious reading of both full charts (Express compatibility and the Couple pack) is paid.
