How dual zodiac works on AstroDual

Western sun signs come from the tropical zodiac and your birth month and day. They sketch a personality style: fire, earth, air, or water; cardinal, fixed, or mutable.

Chinese zodiac animals follow the lunar year of your birth (we use Lunar New Year boundaries, not January 1). They add cultural archetypes and a five-element flavor.

AstroDual shows both side by side so you get a richer snapshot without needing birth time or place. Everything stays on your device.

Compatibility blends Western pair chemistry with Chinese animal dynamics into one harmony score (55% Western / 45% Chinese), plus optional numerology on deeper reports.
