FAQ
What is the difference between nominal age and actual age?
Actual age counts completed solar years from your birthday. Nominal age (xusui) counts 1 at birth and adds 1 every Chinese New Year.
How is the Chinese zodiac determined?
The Chinese zodiac follows lunar years, bounded by Chinese New Year. For example, babies born after CNY 2026 belong to the Horse.
How is the Western zodiac determined?
It depends on your solar birth date, e.g. Aries is Mar 21 - Apr 19.
