The 1991 chinese zodiac sign is the Metal Goat, 辛未 (Xīn Wèi): Yin Metal over the Goat branch, refined metal set on gentle ground. Its Na Yin (纳音 nàyīn) element is 路旁土 Roadside Earth. This year pillar is one of the four columns in a Ba Zi (八字 bāzì) chart, and the piece most people know first about themselves.
Born in January or early February 1991? You may be a Metal Horse
The Goat year turns at Li Chun (立春 lìchūn), the start of solar spring, not on 1 January and not at Chinese New Year. In 1991 that instant fell on 4 February 1991 at 16:08 China Standard Time, the clock Singapore keeps too. Born before that late-afternoon moment and your real year pillar is the Metal Horse (庚午). If your birthday sits near the boundary, confirm it with the calculator rather than trusting the calendar year alone.
The Metal Goat personality, briefly
Yin Metal on the Goat is refined and gentle, artistically inclined, tactful under pressure with a quiet resilience that outlasts its softness. Grace with a spine. The full temperament and its favourable elements are on the Metal Goat year page.
Goat years in the long cycle
Set 1991 in its lineage and the stems rotate on schedule: the 1931 Metal Goat — the identical 辛未 pillar, sixty years before you — then the 1943 Water Goat, the 1967 Fire Goat, the 1979 Earth Goat and the 2003 Water Goat. Beneath the changing stems the Wei branch keeps its three hidden stems: Jǐ 己 (Yin Earth), Dīng 丁 (Yin Fire) and Yǐ 乙 (Yin Wood). For 1991 the interior is double-edged — the branch’s hidden Earth produces the Yin Metal stem while its hidden Fire works on it, support and tempering from the same root. That combination of softness and forge is much of the Metal Goat’s character, and the five variants are compared on the year of the Goat hub.
The hidden Na Yin: Roadside Earth
The 辛未 pillar shows Yin Metal, and its Na Yin (纳音 nàyīn) sound-element is 路旁土 Roadside Earth, the wayside ground it shares with the Metal Horse, since paired pillars sound the same. Refined metal resting on well-trodden earth suits a sign that is graceful on the surface and steadier underneath than it lets on. Na Yin is the traditional secondary layer, useful in older compatibility methods but never a replacement for the working reading of your stems and branches. In sequence, 辛未 is the eighth of the sixty sexagenary pairings, recurring in 1991, 2051 and on the same sixty-year cadence.
The Metal Goat in 2026
A 1991 Goat turns 35 in 2026. The Goat branch forms a six-combination with the Horse (午未合), so meeting the 2026 Fire Horse brings binding, cooperative influences rather than friction — a year that tends to pull alliances, partnerships and commitments toward you. How that combination behaves is explained in the six combinations guide.
For a Metal Goat, a combining year favours alliances and joint ventures over solo effort. The refined, tactful side of your sign works well in that climate, drawing people in. The risk is agreeing to more than you can gracefully carry, since binding energy makes commitment feel easy. Choose your ties with the same care you bring to everything else, and 2026’s cooperative current will work for you rather than around you. A combining year rewards the partnerships you enter on purpose and quietly punishes the ones you drift into.
Settling the 1991 cut-off
Born mid-afternoon on 4 February 1991 — Horse or Goat?
The gate is 16:08. A 15:30 birth that day carries the Metal Horse pillar 庚午; a 16:30 birth carries the Metal Goat 辛未. Note that both candidates are Metal years — the stem barely moves, but the branch, and with it the animal and the whole pillar, changes completely at that minute.
How long did the Metal Goat year last?
From 16:08 on 4 February 1991 to the next Li Chun on 4 February 1992 at 21:48 China Standard Time. That places every January 1992 birth, and most of 4 February 1992, inside your Goat year rather than the Monkey that followed.
No one recorded my birth time. Is my animal still certain?
Unless you were born on 4 February 1991 itself, yes. January 1991 births are Horses; births from 5 February 1991 are Goats; only the boundary day needs a clock. The absent time matters mainly for the hour pillar, the fourth column a full reading is built on.
My papers say 1991 but I arrived on 3 February. Which pillar is mine?
The Metal Horse. Your birth fell a day before the 16:08 boundary, so the 1990 year pillar 庚午 governs your chart even though every document says 1991. This is the routine correction for late-January and early-February births across all years: the civil year names the paperwork, and Li Chun names the pillar. The two agree for most of the year and part company for exactly these few weeks.
Beyond the animal
The animal is a starting point, not an answer to a real question. For compatibility, timing or a decision you are weighing, a reading works from your entire chart in a single hour and leaves you with something written down, not a performance.
A year-branch combination is encouraging, but it is one character out of eight. Whether that cooperative pull is welcome depends on your Day Master and what your chart favours. The five elements primer shows how to weigh it, and the what is my Chinese zodiac guide resolves any other year’s animal.
