The animal comes from the 12-year cycle and the element from the 10-year stem cycle. Births between January 21 and February 20 may belong to the previous zodiac year.

What does this generator create?
Your Chinese zodiac sign is the animal of your birth year on the lunar calendar, and your element is one of five (Wood, Fire, Earth, Metal, Water) assigned in pairs of years. Together they form your sign-and-element combination, which repeats every 60 years.
- The zodiac cycle is 12 animals; the element cycle is 5, so combinations repeat every 60 years.
- The year switches at Lunar New Year (late January to mid-February), not January 1.
- Elements alternate yin and yang years in fixed order: Wood, Fire, Earth, Metal, Water.
- Your animal is the year sign; your element modifies how that sign expresses itself.
How the 12-animal cycle works
The Chinese zodiac assigns one of twelve animals to each lunar year in a fixed order: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig. Your animal is determined by the lunar year in which you were born, which begins between January 21 and February 20 on the Gregorian calendar.
The animals repeat every twelve years, so 1984, 1996, 2008 and 2020 are all Rat years. Within a cycle each animal appears once as a yang year and once as a yin year, which is why two people born in different Rat years can still have different full signatures.
The five elements and the 60-year cycle
Each zodiac year also carries one of five elements, in this order: Wood, Fire, Earth, Metal, Water. Each element governs two consecutive years, one yang and one yin. Because 12 and 5 share no common divisor, the animal-element combination only repeats every 60 years, known as the sexagenary cycle.
The element describes the style or energy the animal brings: Wood signs are described as cooperative and growing, Fire as dynamic and expressive, Earth as steady and practical, Metal as disciplined and resolute, and Water as adaptable and reflective. Traditional interpretation reads the animal as what you are and the element as how you express it.
Why Lunar New Year changes your sign
The most common error in zodiac lookups is using the calendar year instead of the lunar year. Someone born on January 15, 1990 is a Snake, not a Horse, because the Horse year did not begin until January 27, 1990. The boundary moves each year, so a tool that only asks for the birth year is wrong at the margins unless it also checks the exact Lunar New Year date.
This calculator applies the correct boundary date for every year, which matters for roughly one in twelve people: anyone born in January or before the New Year date in February.
What the sign is used for
In Chinese culture the zodiac is used for personality archetypes, compatibility matching, and choosing auspicious years for major events like weddings or business openings. Birth-year signs factor into social customs and even marketing, with demand for baby births spiking in Dragon years.
Treat the personality descriptions as a cultural tradition and a fun lens, not a science. The system's real value for most people is as a shared cultural vocabulary: knowing your sign tells you which year you were born under, which element colors it, and where you sit in the 60-year cycle.
Assumptions and limits
The calculator uses the standard lunisolar New Year dates published for each year and the common animal and element assignments. Regional traditions vary slightly in element philosophy, and some schools assign a fixed element by birth season rather than by year. Results are for cultural and entertainment purposes.
How this calculator works
Formula
Animal = (lunar birth year - 4) mod 12, mapping 0=Rat through 11=Pig. Element = ((lunar birth year - 4) mod 10) // 2, mapping 0=Wood, 1=Fire, 2=Earth, 3=Metal, 4=Water. Years before Lunar New Year belong to the previous zodiac year.
Worked example
Someone born March 1990: (1990-4) mod 12 = 6, the Horse. (1990-4) mod 10 = 6, so element pair index 3 = Metal. Result: Metal Horse. Someone born January 20, 1990 is before that year's Lunar New Year (January 27), so they are an Earth Snake.
Assumptions to verify
- Zodiac year boundaries use standard Lunar New Year dates for each Gregorian year.
- Elements follow the fixed year-pair order (Wood, Fire, Earth, Metal, Water).
- Cultural and entertainment use; descriptions are tradition, not science.
Frequently asked questions
Why is my sign different from other websites?
Most disagreements come from the Lunar New Year boundary. If you were born in January or February, check that the tool you use applies the exact New Year date for your birth year.
What is my element if I was born in a Rat year?
It depends which Rat year: 1984 is Wood Rat, 1996 is Fire Rat, 2008 is Earth Rat, 2020 is Metal Rat. The element cycles independently of the animal.
How often does my exact sign-and-element repeat?
Every 60 years. Someone born in 1990 (Metal Horse) shares the full signature with people born in 1930 and 2050.
Is the zodiac the same as the Chinese year?
The zodiac animal is one layer of the Chinese lunisolar calendar, which also tracks months, days and hours. There is also a zodiac of hours and one of months, which is why full four-pillar astrology is more detailed than year signs alone.
Do the personality descriptions mean anything scientifically?
No. They are a cultural tradition shared across much of East Asia, best treated as a fun framework and a way of marking years, not a predictor of character or fate.
