Born in 1981: the Metal Rooster year
In BaZi the birth year contributes two of your eight characters — a stem and a branch — and they change over at Li Chun, the solar term, not at Lunar New Year and not at midnight on 1 January. For 1981 that instant is 4 February 1981, 05:55 China Standard Time — printed here to the minute because everything below depends on it.
The year pillar, computed
Derived by cycle arithmetic against the same character tables behind every chart this site casts, and asserted against known-good anchors at build time — the same discipline as the verification corpus.
| YEAR PILLAR | 辛 酉Yin Metal · Rooster |
|---|---|
| THE YEAR BEGINS | 4 February 1981, 05:55 CST — Li Chun (立春) |
| BORN BEFORE THAT INSTANT | 庚申 Metal Monkey — the previous year's pillar still applies |
| BORN AFTER IT | 辛酉 Metal Rooster |
If you were born in January or early February
Every 1981 birth before the instant above — all of January and the first days of February — carries 庚申, the Metal Monkey, no matter what a zodiac lookup table printed next to the year “1981” says. Near-boundary charts are where generic lists go wrong; here the boundary is resolved by the astronomical instant, after your local clock time has been converted through historical time zones. Cast your chart and it is settled mechanically. Popular references differ on whether the animal switches at Lunar New Year or at Li Chun — we publish which convention we use, so a disagreement can be classified instead of argued.
What this page does not claim
No personality horoscope keyed to the animal — the year branch is two characters out of eight, and the character a reading is built around is the day master, set by your birth day, not your birth year. What this page certifies is mechanical: which pillar 1981 belongs to, and exactly when it began.
