Each year is associated with one of 12 animals in a rotating cycle: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. Note that the Chinese New Year falls between late January and mid-February, so those born in January-February should verify which zodiac year applies.\n\n### What is the difference between a zodiac sign and a Bazi chart?\n\nYour Chinese zodiac sign is based solely on the birth year and gives a broad personality overview. A full Bazi chart uses all four time units (year, month, day, hour) and provides a much more detailed and personalized destiny analysis. The zodiac sign corresponds to just one of the four pillars in a complete Bazi chart.\n\n### What does it mean to offend Tai Sui (犯太岁)?\n\nTai Sui (太岁) is the Grand Duke Jupiter, a significant annual deity in Chinese astrology. You 'offend' Tai Sui when your zodiac sign clashes with or punishes the current year's zodiac sign. This is believed to bring instability and challenges in that year. Remedies include visiting a Tai Sui temple, wearing specific amulets, or performing appeasing rituals.\n\n### Are Chinese zodiac compatibility predictions reliable?\n\nChinese zodiac compatibility provides a general framework but should not be taken as absolute. True compatibility analysis in Chinese metaphysics requires comparing full Bazi charts to assess Five Element interactions, Day Master compatibility, and shared Luck Pillar timing. Zodiac-only compatibility is a simplified guide.\n\n## Explore More Chinese Metaphysics Tools\n\n- [Bazi Calculator](/bazi/calculator) — Free Four Pillars destiny chart\n- [I Ching Divination](/iching/online) — Online hexagram reading\n- [Fortune Readings](/fortune) — Career, love, wealth, health\n- [Chinese Zodiac Tool](/tools/zodiac) — Zodiac analysis", "faqs": [ { "question": "How is the Chinese zodiac sign determined?", "answer": "The Chinese zodiac sign is determined by the year of birth in the Chinese Lunar Calendar.
