What is Can Chi (Sexagenary cycle)?
Can Chi (干支) names a year, month, or day by pairing one of the 10 Heavenly Stems (Giáp, Ất, Bính…) with one of the 12 Earthly Branches (Tý, Sửu, Dần…) — 60 unique combinations that repeat in a cycle.
What is "tuổi mụ"?
"Tuổi mụ" is the traditional Vietnamese age — you are already 1 at birth, and you add another year every Lunar New Year. It differs from your exact solar age.
Why do I need the Can Chi of the birth year?
Vietnamese tradition uses Can Chi for compatibility checks (weddings, business, moving home), star analysis, and Five-Element fate. It is the foundation of nearly every feng-shui calculation.
