Ji Earth Day Master (己, Yin Earth)
Quick answer: Ji (己) is the sixth of the ten Heavenly Stems: Yin Earth. You have a Ji Earth Day Master if the stem of your day pillar is Ji. The Di Tian Sui pictures Ji as "low and moist", a centred store that holds, and the commentary calls it earth of fields and gardens (田園之土). That image is a way to remember the stem's nature, not a verdict on anyone's personality.

The classical image: what the Di Tian Sui says
The Di Tian Sui (滴天髓) is traditionally attributed to Jing Tu of the Song dynasty, although its authorship is uncertain. It describes each stem in a short verse. This is its verse on Ji:
己土卑濕，中正蓄藏。不愁木盛，不畏水狂。火少火晦，金多金光。若要物旺，宜助宜幫。
"Ji earth is low and moist, centred and upright, a store that holds. It does not worry about abundant wood or fear raging water. With little fire, the fire is dimmed; with much metal, the metal shines. For things to flourish, it needs help and support."
— Di Tian Sui, "天干論", Chanwei text (ctext.org). Wikisource variants include 不畏水旺, 金多金明, 若要物昌. Translation: PillarChart editorial team.
Line by line:
- "Low and moist… a store" (卑濕，蓄藏). Ji is the cultivated, receptive form of Earth. The Wikisource note calls it "earth of fields and gardens" (田園之土), in contrast with Wu's hills and ridges.
- "Does not worry about abundant wood… raging water." Wood controls earth; water is wealth for earth. The verse claims Ji can tolerate more of both than a dry reading might expect — still a stem image, not a promise about any person.
- "Little fire dims fire; much metal makes metal shine." Fire produces earth; earth produces metal. Sparse fire fails to brighten; plentiful metal shows earth's output.
- "Needs help and support." The closing line stresses assistance for things to flourish — climate and structure, not a personality trait of "needy".
Yin, yang and the Earth element
Ji and Wu are the two forms of Earth. Wu is yang (high, firm); Ji is yin (low, moist, field soil).
| Wu | Ji | |
|---|---|---|
| Polarity | Yang Earth | Yin Earth |
| Classical image | Earth of hills and ridges (山岡之土) | Earth of fields and gardens (田園之土) |
| Di Tian Sui opening | 戊土固重 "solid and heavy" | 己土卑濕 "low and moist" |
| Main qi of the branch | 戌 Xu / 辰 Chen | 丑 Chou, 未 Wei |
| Also hidden in | 巳 Si, 寅 Yin | 午 Wu |
| Combines with | 癸 Gui | 甲 Jia |
Read the partner page: Yang Earth (Wu).
Season and climate: why your birth month matters
The month branch tells you the season Ji was born into, and so how much support it starts with. In the seasonal scheme of the Sanming Tonghui, Earth is:
| Season (month branches) | Earth's state | What it means for Ji |
|---|---|---|
| Spring (寅 Yin, 卯 Mao) | Dead 死 | Out of season; wood is Prosperous |
| Summer (巳 Si, 午 Wu) | Strong 相 | Nourished by fire |
| Sixth month (未 Wei) | Prosperous 旺 | Earth's own season in this text |
| Autumn (申 Shen, 酉 You) | Resting 休 | Spending itself on metal |
| Winter (亥 Hai, 子 Zi) | Trapped 囚 | Held back |
The table follows the Sanming Tonghui text, which places Earth's season in the sixth month. The other Earth months (辰, 戌, 丑) are treated in more than one way across schools. See Five Elements.
Climate adjustment in the Qiongtong Baojian
The Qiongtong Baojian (窮通寶鑑) reads every Day Master month by month, asking first whether the chart needs warming, cooling or moistening. Its section on Ji in a key season opens:
正月己土，田园犹冻，盖因腊气未除，余寒未退，故丙为尊。得丙照暖，万物自生。
"Ji earth in the first month: the fields are still frozen, residual cold not yet gone, so Bing is primary. With Bing's warmth, things can grow." — Qiongtong Baojian, 正月己土 (Wikisource). Translation: PillarChart editorial team. Climate / adjustment lines only; the book also contains fixed fortune pronouncements, which we do not reproduce.
For other parts of the year, the book's climate recommendations for Ji include the following (paraphrased):
- Summer: Crops are in the field. The book most likes timely rain — Gui first, Bing next. Without Gui it calls the field drought; without Bing, "orphan yin" (「无癸曰旱田，无丙曰孤阴」).
- Autumn: Things are storing; cold rises. The book wants Bing to warm and Gui to moisten — Gui also drains metal, Bing also controls metal (「须丙火温之，癸水润之…癸先丙后」).
- Winter: Wet mud is frozen. The book takes Bing as primary to thaw, with Jia consulted; it largely sets Wu and Gui aside except when early-winter Ren is strong (「非丙暖不生，取丙为尊」).
These describe what one classical method looks for, given the season. They are not predictions, and other methods may weigh the same chart differently. Where schools disagree on a rule, see How we calculate your chart.
Is your Ji Earth weak or strong?
Three questions decide it, in this order: season (the month branch), roots (Ji among the hidden stems, especially in 丑 Chou, 未 Wei or 午 Wu), and support from other stems (more Earth, or Fire as resource). Our calculator scores this with a published point method. Here are two Ji charts it produced:
A strong Ji: Chicago, 3 July 1988, 10:00 (open)
- Day Master:
- Yin Earth (Ji 己) · Read more about Ji Earth
- Strength:
- 92% · strong (9.2 of 10 points)
Born with month branch Wu 午, when Earth is in a supportive season on our reading, with roots / companions visible in the pillars (戊辰 戊午 己未 己巳). Score: 92%, strong (9.2 of 10 points).
A weak Ji: Chicago, 22 March 1981, 10:00 (open)
- Day Master:
- Yin Earth (Ji 己) · Read more about Ji Earth
- Strength:
- 27% · weak (2.7 of 10 points)
Born with month branch Mao 卯, when Earth is out of its best season on our reading, with limited support among the stems and hidden stems (辛酉 辛卯 己亥 己巳). Score: 27%, weak (2.7 of 10 points).
For what weak and strong mean in general, see Weak Day Master and Strong Day Master. The hidden stems page explains the roots table behind those scores.
Favourable elements. Which element a Ji chart is said to "need" depends on its season, its strength and the reader's method, so there is no single answer for all Ji Day Masters. Our calculator doesn't output a favourable element.
How Ji interacts with the other nine stems
The Yuanhai Ziping names the Ten Gods using Jia as its example, then the same generating / controlling logic is shifted to any Day Master. So for a Ji Day Master:
| Stem | Element | Relation to Ji | Ten God | Notes |
|---|---|---|---|---|
| 甲 Jia | Yang Wood | Controls Ji | Direct Officer (正官) | Combines with Ji (己甲合) |
| 乙 Yi | Yin Wood | Controls Ji | Seven Killings (七殺, also 偏官) | |
| 丙 Bing | Yang Fire | Produces Ji | Direct Resource (印綬, i.e. 正印) | |
| 丁 Ding | Yin Fire | Produces Ji | Indirect Resource (偏印; also 倒食, 梟神) | |
| 戊 Wu | Yang Earth | Same element, opposite polarity | Rob Wealth (劫財) | |
| 己 Ji | Yin Earth | Same element, same polarity | Friend (比肩) | |
| 庚 Geng | Yang Metal | Ji produces it | Hurting Officer (傷官) | |
| 辛 Xin | Yin Metal | Ji produces it | Eating God (食神) | |
| 壬 Ren | Yang Water | Ji controls it | Direct Wealth (正財) | |
| 癸 Gui | Yin Water | Ji controls it | Indirect Wealth (偏財) |
Ji and Jia combine. Jia–Ji is one of the five standard stem combinations. Our calculator doesn't model combinations.
Ji and wood. Wood controls earth. The Di Tian Sui verse is unusually calm about abundant wood for Ji; still read the whole chart.
Ten Gods are labels relative to the Day Master, not personality verdicts. For the naming logic in general, see How we calculate your chart.
Common misconceptions about Ji Earth
- "Ji is my zodiac year element." Day Master ≠ year stem.
- "Ji people are all nurturing / farm-like." The field image describes the stem, not the person.
- "Wood always destroys Ji." The verse itself says Ji does not worry about abundant wood. Schools still weigh wood carefully; there is no single automatic outcome.
- "Ji is just soft mud." The classical text pairs moistness with centred storage and the field-garden image — cultivated earth, not shapeless sludge.
How modern readers describe Ji Earth
Modern guides often associate Ji with receptivity, cultivation and caretaking, extending the field-soil image. Some also mention over-accommodation. These are interpretations built on the classical image, not statements from the classical texts. You may recognise yourself in them or not. Neither result says anything about what will happen to you.
Frequently asked questions
Is Ji Earth yin or yang?
Yin. Ji is Yin Earth, and its yang partner is Wu.
What element is good for a Ji Earth Day Master?
It depends on the season and the chart's strength. There is no single answer. The Qiongtong Baojian recommendations above are one classical climate method; a strength-based reading would favour resource and companions for a weak Ji, and output, wealth and power for a strong one. Our calculator doesn't output a favourable element.
Which stem combines with Ji?
Jia (甲, Yang Wood). Ji–Jia is one of the five classical stem combinations.
Is a Ji Earth Day Master the same as being born in a Earth year?
No. A Earth year means the year stem is one of the two Earth stems. A Ji Day Master means the day stem is Ji. You can have either without the other.
How do I find out if my Day Master is Ji?
Use the Day Master calculator. You only need your birth date (and whether you were born between 23:00 and midnight). The full chart also shows whether your Ji is weak or strong.
Why do some sites call Ji "soil" or "garden earth"?
They follow the commentary's 田園之土. That is a classical image for the stem, not a personality label.
