Twelve Animals, Five Elements, Sixty Years
The Chinese zodiac is one of the oldest and most beloved systems for marking the years, and this calculator unlocks it from a single piece of information: your birth year. Enter it and you will see your zodiac animal — one of the twelve creatures of the cycle, from the quick-witted Rat to the easy-going Pig — together with its fixed element, its yin or yang polarity, and the full sexagenary stem-branch pairing such as “Wood Dragon”. A short note captures the traditional character associated with your animal, the qualities that, by long custom, your birth year is said to lend.
The system is more intricate than the familiar twelve animals alone. Each year also carries one of five elements — Wood, Fire, Earth, Metal and Water — which advance over a ten-year span, two years to each element. Because the twelve animals and the elements (in their yin and yang forms) cycle together, a specific animal-and-element combination returns only once every sixty years. That sixty-year sexagenary cycle has structured the Chinese calendar for millennia, and completing one — turning sixty — remains a milestone birthday worth celebrating. The lone mythical creature among the twelve, the Dragon, is the most auspicious of all, so much so that Dragon years tend to see a noticeable rise in births.
A couple of cultural details are worth keeping in mind. The zodiac year does not begin on 1 January but at Chinese New Year, which falls somewhere between late January and mid-February on the lunar calendar; so anyone born in those early weeks may actually belong to the previous year’s animal, and should check that year’s festival date. The twelve-animal cycle is shared widely across East and Southeast Asia — China, Vietnam, Korea, Japan and more — with charming local variations, such as Vietnam’s use of the Cat where China has the Rabbit. The personality traits here are offered in the spirit they are meant: a rich, enjoyable tradition for insight and conversation rather than a scientific reading. Explore your sign, share it with family, and remember that the whole calculation runs in your browser, so your birth year never leaves your device.
Animal and element turn together, so your exact sign — Wood Dragon, Metal Rat — comes round just once every sixty years.

Frequently Asked Questions
- It is set by your birth year. The zodiac runs in a repeating cycle of twelve animals — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig — so each year corresponds to one animal, and the cycle repeats every twelve years. Enter your year and the calculator returns your animal, element and yin-yang polarity.
- Beyond the animal, each year is associated with one of five elements — Wood, Fire, Earth, Metal and Water — which cycle over ten years (two years per element). Combining the twelve animals with the five elements produces sixty unique pairings, such as Wood Dragon or Metal Rat, which is the basis of the sixty-year sexagenary cycle.
- Because the twelve animals and the ten heavenly stems (the five elements in yin and yang forms) advance together, a given animal-and-element combination recurs only once every sixty years. This sexagenary cycle has been used for counting years in China for millennia, and turning sixty — completing a full cycle — is a major birthday celebration.
- No. The Chinese zodiac year begins at Chinese New Year, which falls between late January and mid-February depending on the lunar calendar. So someone born in January or early February may belong to the previous year’s animal. This calculator uses the calendar year as a simple guide; if your birthday is near the new year, check the exact date of that year’s festival.
- The Dragon is widely regarded as the most auspicious and powerful sign, associated with success, ambition and good fortune, and Dragon years often see a rise in births. That said, every animal has its own admired strengths, and beliefs about luck vary by region and family, so no sign is truly “better” than another.
- Each year is also classified as yin or yang, alternating year by year. Yang years (even years in this scheme) are associated with active, outward energy, and yin years (odd years) with receptive, inward energy. Combined with the animal and element, it adds another layer to the traditional character of a birth year.
- Your benmingnian is the return of your own zodiac animal, which happens every twelve years — at ages 12, 24, 36 and so on. Tradition holds that your zodiac year can be unlucky, and people often wear red, given as gifts, to ward off misfortune during it. It is one of the most well-known zodiac customs.
- The twelve-animal cycle is shared across much of East and Southeast Asia, including China, Vietnam, Korea, Japan and beyond, though there are local variations — Vietnam famously uses the Cat in place of the Rabbit. The underlying year-by-animal system, however, is broadly the same wherever it is observed.
- They are a fun part of a rich cultural tradition rather than a scientific assessment. The character notes reflect long-standing associations with each animal, enjoyed for insight and entertainment. Treat your sign as a piece of heritage and conversation rather than a prediction about who you are.

Method & sources
How it computes
The sexagenary cycle (ganzhi): ten heavenly stems against twelve earthly branches, repeating every sixty years. The animal comes from the branch. The trap is the year boundary — the zodiac year starts at Chinese New Year, which falls between 21 January and 20 February, so anyone born in January or early February belongs to the PREVIOUS animal.
What this tool implements
- The year boundary is Chinese New Year, not 1 January. A birthday on 2 February 1997 is a Rat, not an Ox, and getting this wrong is the single most common error in zodiac tools.
- Chinese New Year dates are computed from the astronomical calendar defined by GB/T 33661-2017, not approximated from a rule of thumb.
- ⚠️ The BaZi hour and month pillars use the solar terms, where the year begins at lichun in early February rather than at Chinese New Year. The two systems disagree by days to weeks, and which one applies depends on what you are calculating.
- The animal is the branch alone. A full ganzhi designation carries the stem too, which is what makes the cycle sixty years rather than twelve.

What can make this go out of date
- None at runtime. New-year dates ship with the page across the supported year range rather than being approximated.
