I was born in the Year of the Ox. Most people understand this to be the Chinese Zodiac. In case you meet someone who doesn't understand, you can say: It is the Chinese Zodiac. If you want to explain further, you just say that the Sign of the Zodiac changes yearly, not monthly.

my born years? 呵呵，不知道对不对啊

Zodiac = circle of animals The phrase "zodiacal year" does not make sense. Try these: The Chinese 12-Year Cycle. The Chinese Zodiac. The 12 Signs of the Chinese Zodiac.

I guess Zodiacal Year
