Enter your birthday above to find your exact animal, Five Element (五行), Heavenly Stem & Earthly Branch (干支), Yin/Yang energy, lucky colors, numbers, direction, flower, and guardian Buddha (本命佛). Covers 1900–2099 with exact Spring Festival dates.
Yin & Yang: The Two Energies Behind Your Sign
In short: Yin and Yang are the two complementary cosmic forces in Chinese philosophy. Yang signs (Rat, Tiger, Dragon, Horse, Monkey, Dog) are active and outward-driven; Yin signs (Ox, Rabbit, Snake, Goat, Rooster, Pig) are receptive and introspective. Each person contains both energies, but one dominates based on birth year.
Every Chinese zodiac sign carries either Yin (阴) or Yang (阳) energy. This duality — rooted in Daoist philosophy — shapes how your animal sign expresses itself in personality, decision-making, and relationships.
Yang (阳) Signs — Active Energy
Rat, Tiger, Dragon, Horse, Monkey, Dog
Bold, outward-focused, assertive, driven. Yang signs tend to charge ahead, take initiative, and express energy outward. Associated with the sun, fire, and the masculine principle.
Yin (阴) Signs — Receptive Energy
Ox, Rabbit, Snake, Goat, Rooster, Pig
Calm, introspective, nurturing, intuitive. Yin signs are reflective, patient, and process internally. Associated with the moon, water, and the feminine principle.
Everyone contains both Yin and Yang energy — no one is purely one or the other. Your zodiac classification simply indicates which tendency is more dominant in your nature. Understanding your dominant energy helps you recognize your natural rhythm and find balance.
The 60-Year Sexagenary Cycle (六十甲子)
In short: The Chinese sexagenary cycle combines 10 Heavenly Stems with 12 Earthly Branches, producing 60 unique year-labels. Each year gets one stem and one branch, cycling every 60 years. 2026 is Bing-Wu (丙午) — Yang Fire Horse — last seen in 1966, next in 2086.
Your zodiac sign is more than just an animal. Each year in the Chinese system is labeled with a unique combination of one Heavenly Stem (天干) and one Earthly Branch (地支). Since there are 10 stems and 12 branches, the full cycle takes 60 years to complete — meaning no two years in a 60-year span share the same stem-branch combination.
The 10 Heavenly Stems (天干)
| Stem | Chinese | Element | Polarity | Personality |
|---|---|---|---|---|
| Jia | 甲 | Yang Wood | Yang | Sturdy oak, principled, stubborn |
| Yi | 乙 | Yin Wood | Yin | Flexible vine, adaptable, creative |
| Bing | 丙 | Yang Fire | Yang | Blazing sun, charismatic, bold |
| Ding | 丁 | Yin Fire | Yin | Candle flame, meticulous, warm |
| Wu | 戊 | Yang Earth | Yang | Mountain, reliable, grounded |
| Ji | 己 | Yin Earth | Yin | Fertile soil, nurturing, receptive |
| Geng | 庚 | Yang Metal | Yang | Axe blade, decisive, disciplined |
| Xin | 辛 | Yin Metal | Yin | Jewelry, refined, precise |
| Ren | 壬 | Yang Water | Yang | Great ocean, powerful, restless |
| Gui | 癸 | Yin Water | Yin | Morning dew, gentle, wise |
Lunar New Year vs. Lichun: Two Zodiac Systems
In short: The zodiac year starts on Chinese New Year (Jan 21–Feb 20) in the mainstream system, or on Lichun/Start of Spring (Feb 3–5) in the BaZi system. For births in late January to early February, these two systems may assign different animal signs. This calculator uses the mainstream Lunar New Year system.
There is a common debate in Chinese astrology: when exactly does the zodiac year begin? Two systems exist, and for most of the year they produce the same result — but for people born in late January to early February, they can disagree.
System 1: Lunar New Year (春节)
Used by: Mainstream Chinese culture, folk tradition, daily life
The zodiac changes on Chinese New Year’s Day (1st day of the 1st lunar month). Falls between January 21 – February 20. This is what most Chinese people use to determine their animal sign, and what our calculator uses by default.
System 2: Lichun (立春 — Start of Spring)
Used by: BaZi (Four Pillars) astrology, traditional fortune-telling
The zodiac changes on Lichun, the first solar term, which falls on February 3, 4, or 5 each year. This system is used in professional BaZi chart casting. For a full BaZi reading, Lichun is the correct boundary.
⚠ Example of disagreement: Someone born on February 8, 2024:
• Lunar New Year system: Dragon (CNY was Feb 10 — they’re before it, so Rabbit)
• Lichun system: Dragon (Lichun was Feb 4 — they’re after it, so Dragon)
Two systems, two different animals! Our calculator uses the Lunar New Year system (mainstream). For BaZi-specific readings, use our BaZi Calculator which follows Lichun.

How It Works
About This Calculator
This Chinese Zodiac Analyzer is an interactive tool that determines your zodiac animal sign from your birth date. It uses exact Chinese New Year (Spring Festival) dates from 1900 to 2099 — sourced from the Purple Mountain Observatory and the Hong Kong Observatory — to handle the lunar calendar boundary accurately.
What it returns: Zodiac animal (12 animals), Five Element (Wood/Fire/Earth/Metal/Water), Heavenly Stem & Earthly Branch (干支), Yin/Yang polarity, lucky colors, lucky numbers, lucky direction, lucky flower, and guardian Buddha (本命佛).
What it does NOT do: This tool is not a full BaZi (Four Pillars) chart — it analyzes the birth year pillar only. For month, day, and hour pillar analysis, use the BaZi Calculator. For relationship compatibility between two signs, use our Compatibility Calculator.
Methodology & Data Accuracy
This calculator converts Gregorian (solar) dates to the Chinese lunar calendar using precise Spring Festival (Chinese New Year) dates for each year from 1900 to 2099. The data is sourced from Purple Mountain Observatory (Zijinshan, Nanjing) and the Hong Kong Observatory — the two authoritative bodies for Chinese astronomical calendar computation.
Time zone: All calculations use UTC+8 (China Standard Time), which is the official time zone for Chinese lunar calendar determination. Users in other time zones should enter their date of birth as recorded on their birth certificate (the Gregorian date).
Leap months: The Chinese lunar calendar includes intercalary (leap) months approximately every 2–3 years to stay aligned with the solar cycle. However, since the zodiac animal changes only at Spring Festival (the 1st day of the 1st lunar month), leap months do not affect zodiac sign determination — only the exact date of Spring Festival matters.
Review cycle: The Spring Festival date table is reviewed annually against the latest Purple Mountain Observatory publications. The last full data review was completed in August 2026, covering years 1900–2099. Any corrections to official CNY dates are applied within 30 days of publication.
