Chinese Zodiac Calculator

In Chinese culture, the zodiac (Shengxiao) is a repeating 12-year cycle of animal signs and their ascribed attributes, based on the lunar calendar. Unlike Western astrology, which focuses on constellations and months, the Chinese Zodiac is primarily focused on the year of birth.

This calculator helps you identify your lunar sign, your elemental influence, and provides insights into your personality, lucky symbols, and romantic compatibility.

What is the Chinese Zodiac?

The Chinese Zodiac is a classification scheme based on the lunar calendar that assigns an animal and its reputed attributes to each year in a repeating 12-year cycle. The 12 animals are, in order: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig.

Beyond the animals, Chinese astrology incorporates the Five Elements (Wood, Fire, Earth, Metal, and Water) and the concept of Yin and Yang. Together, these create a 60-year cycle (12 animals × 5 elements). Each element appears for two consecutive years—one year being Yang and the next being Yin.

The Formula

To calculate the Chinese Zodiac animal and element, we use the lunar year ($Y_L$). Note that if you were born in January or early February, your lunar year might be the previous Gregorian year.

Finding the Animal Index ($A$)

The animal is determined by the remainder of the lunar year minus 4, divided by 12:

$A = (Y_L - 4) \pmod{12}$

Where the index $A$ corresponds to: 0: Rat, 1: Ox, 2: Tiger, 3: Rabbit, 4: Dragon, 5: Snake, 6: Horse, 7: Goat, 8: Monkey, 9: Rooster, 10: Dog, 11: Pig.

Finding the Element

The element is determined by the last digit of the lunar year:

• 0 or 1: Metal
• 2 or 3: Water
• 4 or 5: Wood
• 6 or 7: Fire
• 8 or 9: Earth

Worked Examples

Example 1: Born May 15, 1990

• Gregorian Year: 1990
• Lunar Adjustment: May is well after February, so $Y_L = 1990$.
• Animal Calculation: $(1990 - 4) \pmod{12} = 1986 \pmod{12} = 6$. Index 6 is the Horse.
• Element: Year ends in 0, which is Metal.
• Result: Metal Horse.

Example 2: Born January 10, 1985

• Gregorian Year: 1985
• Lunar Adjustment: January 10 is before the 1985 Lunar New Year (Feb 20), so $Y_L = 1984$.
• Animal Calculation: $(1984 - 4) \pmod{12} = 1980 \pmod{12} = 0$. Index 0 is the Rat.
• Element: Year ends in 4, which is Wood.
• Result: Wood Rat.

FAQ

Why does my sign change if I was born in January?

The Chinese Zodiac follows the Lunar Calendar. Chinese New Year usually falls between January 21 and February 20. If you were born before the Lunar New Year, you belong to the zodiac sign of the previous year.

What are the Five Elements?

The elements are Wood, Fire, Earth, Metal, and Water. They represent different types of energy that modify the basic characteristics of the animal sign.

Is Chinese Zodiac the same as Western Astrology?

No. Western astrology is based on the month of birth and the position of the sun relative to constellations. Chinese astrology is based on the year of birth and the lunar cycle.

How accurate is the compatibility?

Compatibility is based on traditional folklore and the "Four Pillars of Destiny." It is intended for entertainment and cultural insight rather than scientific prediction.

What is a Ben Ming Nian?

Your "Zodiac Year of Birth" (Ben Ming Nian) occurs every 12 years. Traditionally, it is thought to be a year of challenges where one should be cautious.
