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 Ox hides Yin Earth (己, Eating God), Yin Water (癸, Seven Killings), Yin Metal (辛, Indirect Wealth); the Tiger hides Yang Wood (甲, Direct Resource), Yang Fire (丙, Rob Wealth), Yang Earth (戊, Hurting Officer); the Rooster hides Yin Metal (辛, Indirect Wealth).
- 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.
- Eating God (Shi Shen, 食神)
- What you produce, same polarity. Output that comes easily: making, feeding, expressing, without strain.
- 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.
- Indirect Wealth (Pian Cai, 偏财)
- What you control, same polarity. Wealth that comes sideways rather than by salary — the uneven kind.
- Direct Officer (Zheng Guan, 正官)
- What controls you, opposite polarity. Authority in its orderly form: office, rule, the structure you fit into.
- Direct Resource (Zheng Yin, 正印)
- What produces you, opposite polarity. Straightforward support: what teaches, shelters and backs you.
- 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.
- 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
Yin Fire (丁) is soft within, its inner nature bright and blending. Embracing Yin Wood (乙) it is filial, binding Yang Water (壬) it is loyal. Strong, it is not fierce; declining, it is not spent. If it has a true mother, it can take autumn or winter.
丁火柔中，内性昭融，抱乙而孝，合壬而忠，旺而不烈，衰而不穷，如有嫡母，可秋可冬。
Born in a Tiger month (Yin, 寅), when Wood rules the season. In that season Yin Fire is rising (Xiang, 相): the season produces it. (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: Fire Rooster (Ding You, 丁酉)
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 Fire below the Mountain (山下火), and it says:
The echo of spirits: fire that has no form; likes the Dragon, Dog, Ox and Goat.
The original Chinese
鬼神之灵响，火无形者，喜辰戌丑未

Elements in the six known characters
All five elements appear among the six known characters. Hidden stems are not counted here.
All twelve hours, cast one by one
Of the twelve hours, 2 read strong and 10 weak (strong: the Snake, Horse hours). Strength, and the useful element that follows from it, depend on the hour — the date alone cannot settle them.

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.
Aaron Chia’s bone weight (Cheng Gu, 称骨)
Lunar date: day 18 of the 1st month, Fire Ox year (丁丑年正月十八). Its weights: year 0.8 liang, month 0.6 liang, day 1.8 liang — 3.2 liang before the hour. Over the twelve hours that makes 3.8 liang to 4.8 liang.
This date falls on a cell where one of the four published tables differs, which would move every total by 1.0 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
The full report reads 2027 month by month from your own birth date, time and place.
