2031: Year of the Metal Pig
2031 is the Year of the Metal Pig (金豬, 辛亥) in the Chinese zodiac. This is a Yin Metal year, governed by the Heavenly Stem Xin 辛 and the Earthly Branch Hai (亥).
In the sexagenary cycle (六十甲子), 2031 occupies position #48 of 60. The cycle has been used continuously since the Shang Dynasty (c. 1600 BCE) to count years, and it takes 60 years to complete one full revolution.
In the traditional Chinese calendar, the zodiac year in BaZi (Four Pillars of Destiny) tradition starts at Lichun (立春), the "Start of Spring" solar term, which typically falls on February 3rd, 4th, or 5th. People born before Lichun in 2031 belong to the previous zodiac year.

Metal Element (金) in 2031
The Metal element from the Heavenly Stem combines with the Pig's fixed element of Water (水) to create the unique energy signature of 2031. In Wu Xing (Five Elements) theory, these two elements interact through the generating (相生) and overcoming (相剋) cycles.
The yearly Metal element generates the Pig's innate Water element in the productive cycle (相生). This creates a harmonious flow of energy — the Heavenly Stem supports and nourishes the animal's natural strengths.
The Metal Pig carries Yin polarity. In Chinese cosmology, Yin energy represents receptive, inward, and reflective force — diplomacy, intuition, and careful cultivation.

2031 Pig Compatibility
Zodiac compatibility in Chinese astrology is determined by the Earthly Branch (animal sign), not the Heavenly Stem (element). The Pig's key compatibility relationships:
- San He (三合) — Zodiac Trio: The Pig forms a harmonious triad with the Rabbit and the Goat, creating natural cooperation and shared goals.
- Liu He (六合) — Secret Friend: The Pig's "secret friend" is the Tiger, a pairing that creates deep, intuitive understanding.
- Six Clash (六衝): The Snake sits directly opposite the Pig on the zodiac wheel. This creates tension but also complementary growth potential.

2031 in BaZi (Four Pillars)
In BaZi (八字) astrology, 2031 contributes the Year Pillar of 辛亥 (Xinhai) to your Four Pillars chart. This pillar pairs the Heavenly Stem 辛 (Xin) with the Earthly Branch 亥 (Hai).
The Year Pillar represents your relationship with society, your ancestral influence, and your public persona. It is the outermost of the four pillars and shapes how others perceive you and how you relate to the broader world.

The Sexagenary Cycle Position
2031 is position #48 in the sexagenary cycle (六十甲子, liùshí jiǎzǐ). The cycle combines 10 Heavenly Stems with 12 Earthly Branches to produce 60 unique stem-branch pairs. Since 10 and 12 share a common factor of 2, only 60 (not 120) combinations occur.
The same 辛亥 pillar last appeared in 1971 and will next appear in 2091. The same Pig animal (but with a different element) last appeared in 2019 and will next appear in 2043.
