Tony Tan’s BaZi chart 陈庆炎
President of Singapore, 2011–2017 · born 7 February 1940, Singapore · date source: Wikipedia
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
Tony Tan’s day master is Yang Metal: the Sword.
Brave and firm, and stands by what is right. 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 Dragon hides Yang Earth (戊, Indirect Resource), Yin Wood (乙, Direct Wealth), Yin Water (癸, Hurting Officer); the Tiger hides Yang Wood (甲, Indirect Wealth), Yang Fire (丙, Seven Killings), Yang Earth (戊, Indirect Resource); the Dragon hides Yang Earth (戊, Indirect Resource), Yin Wood (乙, Direct Wealth), Yin Water (癸, Hurting Officer).
- Friend (Bi Jian, 比肩)
- Same element, same polarity as you. A peer: someone standing where you stand, competing for the same thing and equally able to share the load.
- Indirect Resource (Pian Yin, 偏印)
- What produces you, same polarity. Support of an indirect kind — the tradition treats it as nourishment that can also crowd out the Eating God (食神).
- 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.
- Indirect Wealth (Pian Cai, 偏财)
- What you control, same polarity. Wealth that comes sideways rather than by salary — the uneven kind.
- Seven Killings (Qi Sha, 七杀)
- What controls you, same polarity. Pressure with nothing softening it: demand, risk, and whatever you answer to whether you chose it or not.
Day master
What the classic Di Tian Sui (滴天髓) says of this stem, word for word
Yang Metal (庚) carries the killing force (Sha, 煞) and is hard and strong above all. Getting Water it is clear; getting Fire it is keen. Earth moist and it is produced; Earth dry and it is brittle. It can beat elder brother Yang Wood (甲) and loses to younger sister Yin Wood (乙).
庚金带煞，刚健为最，得水而清，得火而锐，土润则生，土干则脆，能赢甲兄，输于乙妹。
Born in a Tiger month (Yin, 寅), when Wood rules the season. In that season Yang Metal 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.)
Elements in the six known characters
None of the six is Fire, Water. 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 Metal day master reads strong. Whatever the hour, the support-and-restrain method favours Water, Wood, Fire — 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.
Tony Tan’s bone weight (Cheng Gu, 称骨)
Lunar date: day 30 of the 12th month, Earth Rabbit year (己卯年腊月三十). Its weights: year 1.9 liang, month 0.5 liang, day 0.6 liang — 3.0 liang before the hour. Over the twelve hours that makes 3.6 liang to 4.6 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.
