Born in January or early February 1991? Two rules, two answers
| Rule | Animal changes on | Used by |
|---|---|---|
| Lunar New Year | 15 February 1991 | Most Chinese zodiac charts, calendars and apps |
| Lichun / Ipchun (Start of Spring) | 4 February 1991 at 17:08 Korea time | Chinese BaZi and Korean Saju (Four Pillars) |
So if you were born between 4 February and 15 February 1991, your BaZi/Saju year pillar is already the Metal Goat, while a zodiac chart still calls you a Metal Horse. Before both dates you are a Metal Horse by either rule. Neither rule is "wrong" — they answer different questions: the Lunar New Year rule is a calendar custom, the Lichun rule is the one an actual birth chart is built on.
The 1991 year pillar: 辛未
Sin (辛) is Yin Metal. Refined, exacting, and quietly proud. More about Sin Metal.
Mi (未) is the Goat: late summer, Yin Earth that stores heat and wood. It carries care and stubborn gentleness.
Inside the pillar, the branch's Earth feeds the stem's Metal, so the branch supports the stem. That is the year's own texture — but the year pillar only sets the background of a chart. It describes the generation and the family setting you were born into more than you personally.
1991 month by month: when each Saju month begins
Saju months do not start on the 1st. Each begins at a solar term, and the exact moment shifts every year. A birthday near one of these times can change the month pillar — and with it the whole reading of the chart.

Compatible and clashing animals for the Goat
By the classic branch rules, the Goat (未) forms a harmony (三合 or 六合) with the Rabbit, Horse, Pig, and clashes (沖) with the Ox. Year-branch compatibility is the broadest layer of matching; a real compatibility reading compares day pillars.
Your animal is not your Day Master
Everyone born in 1991 after Ipchun shares the Metal Goat. What makes a chart personal is the day pillar, and above all its first character — the Day Master. There are ten:
The same 辛未 pillar returns every 60 years: 1931 and 2051.

Frequently asked questions
- What zodiac animal is 1991?
- The Metal Goat (Yin), year pillar 辛未. People born from 4 February 1991 at 17:08 Korea time onward in 1991 are Metal Goats.
- I was born in January 1991. What is my animal?
- The Metal Horse of 1990. In Saju the year changes at Ipchun (4 February 1991 at 17:08 Korea time), so January births and early-February births before that moment belong to the previous year.
- What is the 1991 year pillar in Saju?
- 辛未, romanized Sin-mi: Sin (Yin Metal) over Mi (Goat).
- Is the Korean zodiac the same as the Chinese zodiac?
- The animals and the sixty-year cycle are the same. Korean Saju, like Chinese Bazi, changes the year at Ipchun (around 4 February), not at Lunar New Year.
- How do I know my Day Master in K-Saju?
- Your Day Master (Ilgan) is the Heavenly Stem of your birth day pillar among the 10 stems (Gap/Eul Wood, Byeong/Jeong Fire, Mu/Gi Earth, Gyeong/Sin Metal, Im/Gye Water). Enter your birth year, month, and day in the HeartLoop calculator on this page to compute your exact Day Master and Five Elements ratio in 3 seconds.
- What is my 2027 fortune based on my birth date?
- 2027 is the Year of the Red Fire Goat (Ding-Mi, 丁未). Rather than relying on birth-year zodiac alone, HeartLoop cross-references 2027 Fire-Earth energy against your personal Day Master and solar-term month pillar to pinpoint your peak months for career, wealth, and love.
