Question 1

What is a Zodiac Synastry Calculator?

Accepted Answer

A Zodiac Synastry Calculator compares two individual birth charts (natal charts) to analyze how the planets in one person's chart interact with the planets in the other's. It reveals emotional connection (Moon), attraction (Venus & Mars), and communication dynamics (Mercury).

Question 2

How does synastry differ from sun sign compatibility?

Accepted Answer

Sun sign compatibility only looks at your basic zodiac sign, which accounts for less than 10% of relationship dynamics. Synastry evaluates all major celestial placements—including Sun, Moon, Mercury, Venus, Mars, and rising signs—providing a comprehensive 360-degree compatibility report.

Question 3

Do I need exact birth times for a synastry reading?

Accepted Answer

While exact birth times provide the highest accuracy (especially for Moon sign and Rising sign / Ascendant), you can still calculate meaningful planetary aspects (Sun, Venus, Mars, Mercury) with just birth dates.
