Frequently asked questions

How is compatibility calculated?

From the two sun signs and their classical elements — signs of the same element harmonize, while complementary elements (fire+air, earth+water) balance each other. It is for fun and self-reflection, not a verdict on any real relationship.

Does the order of signs matter?

No. Compatibility is symmetric here, so “Aries & Leo” and “Leo & Aries” give the same result. We cache each pair once, which keeps the tool fast and free.

Can two “incompatible” signs work?

Absolutely. Every pairing has real strengths and real growth areas. A lower score just points to areas worth communicating about — not a reason two people can’t thrive together.

What is Zodiac Compatibility (Synastry)?

Zodiac compatibility — technically synastry in astrology — compares two birth charts to understand relationship dynamics. Far beyond "are Leos and Scorpios compatible?", real synastry examines how each person's planets interact: your Venus to their Mars, their Moon to your Saturn, creating a unique relational fingerprint.

The three most revealing placements are the Sun (core identity match), Moon (emotional compatibility), and Rising sign (first-impression chemistry). Synastry is best treated as a conversation starter and a framework for understanding differences, not a pass/fail test for a relationship.
