Born in January or early February 2010? Two rules, two answers
| Rule | Animal changes on | Used by |
|---|---|---|
| Lunar New Year | 14 February 2010 | Most Chinese zodiac charts, calendars and apps |
| Lichun / Ipchun (Start of Spring) | 4 February 2010 at 07:47 Korea time | Chinese BaZi and Korean Saju (Four Pillars) |
So if you were born between 4 February and 14 February 2010, your BaZi/Saju year pillar is already the Metal Tiger, while a zodiac chart still calls you a Earth Ox. Before both dates you are a Earth Ox 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 2010 year pillar: 庚寅
Gyeong (庚) is Yang Metal. Decisive, blunt, and strong under pressure. More about Gyeong Metal.
In (寅) is the Tiger: the opening of spring, Yang Wood. It carries initiative and the urge to begin.
Inside the pillar, the stem's Metal controls the branch's Wood, so the stem presses on the branch. 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.
2010 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 Tiger
By the classic branch rules, the Tiger (寅) forms a harmony (三合 or 六合) with the Horse, Dog, Pig, and clashes (沖) with the Monkey. 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 2010 after Ipchun shares the Metal Tiger. What makes a chart personal is the day pillar, and above all its first character — the Day Master. There are ten:
The same 庚寅 pillar returns every 60 years: 1950 and 2070.

Frequently asked questions
- What zodiac animal is 2010?
- The Metal Tiger (Yang), year pillar 庚寅. People born from 4 February 2010 at 07:47 Korea time onward in 2010 are Metal Tigers.
- I was born in January 2010. What is my animal?
- The Earth Ox of 2009. In Saju the year changes at Ipchun (4 February 2010 at 07:47 Korea time), so January births and early-February births before that moment belong to the previous year.
- What is the 2010 year pillar in Saju?
- 庚寅, romanized Gyeong-in: Gyeong (Yang Metal) over In (Tiger).
- 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.
