Terence Tao’s BaZi chart 陶哲轩
Mathematician · Fields Medal, 2006 · born 17 July 1975, Adelaide, South Australia, Australia · date source: Wikipedia
Western zodiac sign: Cancer.
No birth time has been published. The date fixes three of the four pillars; the fourth is one of twelve. Below, everything the date settles is computed, and everything that turns on the hour is cast all twelve ways — without picking one on anyone’s behalf.
In short
Terence Tao’s day master is Yang Wood: the Great Tree.
Upright and caring: wants to do some good in the world. The day master comes from the day of birth alone; about one person in ten shares it.

What the labels mean
Each pillar is two characters: a stem on top (an element, yin or yang) and a branch below (one of the twelve zodiac animals). The day stem is the day master — the person. The label above each other stem is its ten god (Shi Shen, 十神): what that element is to the day master.
Each animal also hides stems of its own, strongest first: the Rabbit hides Yin Wood (乙, Rob Wealth); the Goat hides Yin Earth (己, Direct Wealth), Yin Fire (丁, Hurting Officer), Yin Wood (乙, Rob Wealth); the Rat hides Yin Water (癸, Direct Resource).
- Rob Wealth (Jie Cai, 劫财)
- Same element, opposite polarity. A peer who takes rather than shares — the tradition reads it as what draws on your resources through people close to you.
- Direct Resource (Zheng Yin, 正印)
- What produces you, opposite polarity. Straightforward support: what teaches, shelters and backs you.
- Direct Wealth (Zheng Cai, 正财)
- What you control, opposite polarity. Wealth held steadily — earned, kept, accounted for.
- Hurting Officer (Shang Guan, 伤官)
- What you produce, opposite polarity. Output with an edge on it. The name means it injures the Direct Officer (正官), which is why the tradition reads it as talent that does not sit well with authority.
Day master
What the classic Di Tian Sui (滴天髓) says of this stem, word for word
Yang Wood (甲) reaches to heaven: to shed its husk it wants Fire; in spring it will not tolerate Metal, in autumn it will not tolerate Earth. With Fire blazing it rides the dragon; with Water flooding it straddles the tiger. Ground moist and heaven mild, it stands planted a thousand years.
甲木参天，脱胎要火，春不容金，秋不容土，火炽乘龙，水宕骑虎，地润天和，植立千古。
Born in a Goat month (Wei, 未), when Earth rules the season. In that season Yang Wood is imprisoned (Qiu, 囚): held down by what the season produces. (One of five seasonal states, Wang Xiang Xiu Qiu Si, 旺相休囚死, after the San Ming Tong Hui, 三命通會, book 2.)
Day pillar: Wood Rat (Jia Zi, 甲子)
The classic San Ming Tong Hui (三命通会) gives each of the sixty day pillars an image, its sound element (Na Yin, 纳音). For this one it is Gold in the Sea (海中金), and it says:
A treasure; likes places where Metal and Wood are strong.
The original Chinese
为宝物，喜金木旺地
This is what the book says of every Jia Zi day, not of Terence Tao. The Jia Zi day pillar › (what the classic says at each birth hour, what the branch holds, and others born on one)
Elements in the six known characters
None of the six is Fire, Metal. The hour pillar’s two characters may supply it or may not — that depends on the hour. Hidden stems are not counted here.
All twelve hours, cast one by one
In all twelve hours the Yang Wood day master reads strong. Whatever the hour, the support-and-restrain method favours Fire, Earth, Metal — the date alone settles it.

Each row is exactly what the full calculator would say for a birth in that hour. Strength comes from three tests: in season (De Ling, 得令) — born in the season of the day master’s own element; rooted (De Di, 得地) — the same element hidden in a branch; backed (De Shi, 得势) — as much support around it as drain. Two of three reads strong. The favoured elements come from support and restrain (Fu Yi, 扶抑): a strong day master wants draining, a weak one wants support. There are three other methods for the useful element — climate (Tiao Hou, 调候), bridging (Tong Guan, 通關) and disease and cure (Bing Yao, 病藥) — each from its own text; see the useful god page. Hours are solar time at the birthplace, so a clock time needs correcting first; and a birth after 23:00 falls in the late Rat hour, where the two schools disagree about whether the day has turned.
Terence Tao’s bone weight (Cheng Gu, 称骨)
Lunar date: day 9 of the 6th month, Wood Rabbit year (乙卯年六月初九). Its weights: year 0.8 liang, month 1.6 liang, day 0.8 liang — 3.2 liang before the hour. Over the twelve hours that makes 3.8 liang to 4.8 liang.
Bone weighing is a folk almanac sum over the calendar positions of the year, month, day and hour — not the elements, and not the chart above. How heavy is heavy? The tables and the spread ›
And yours?
You have your own birth time, so your chart needs no table of twelve — all four pillars, corrected to true solar time with the timezone actually in force where and when you were born.
About this page
This page computes; it does not interpret. The birth date is public and its source is linked; the birth time is not, so the hour pillar and everything that depends on it are set out all twelve ways.
Nothing here claims that anyone is who they are because of a chart, and nothing here forecasts years, health or lifespan for anyone living.
Your own 2027, month by month
