A mao month bazi birth places you in the Rabbit month (卯 Mǎo), the second month of the Ba Zi (八字 bāzì) year and the heart of spring. In Ba Zi the month pillar (月柱 yuèzhù) is the season pillar, and it is the single strongest influence on whether your Day Master (日主 rìzhǔ) reads strong or weak. Where the Tiger month was spring just waking, the Rabbit month is spring fully open.
The Rabbit month begins at the solar term Jing Zhe (惊蛰 Jīngzhé), around 6 March, not at the start of any calendar month. Ba Zi months turn on solar terms (节气 jiéqì), so a birth in the first days of March may still belong to the Tiger month. When your birth sits near the boundary, verify the exact turning point with the free chart calculator rather than assuming the month from the date alone.
Your mao month bazi pillar by year stem
The month stem is fixed by your year stem through the Five Tigers rule (五虎遁 wǔhǔ dùn). Find your year stem and read across to the Rabbit-month pillar.
| Year stem | Rabbit month pillar |
|---|---|
| 甲 Jiǎ | 丁卯 Dīng Mǎo |
| 乙 Yǐ | 己卯 Jǐ Mǎo |
| 丙 Bǐng | 辛卯 Xīn Mǎo |
| 丁 Dīng | 癸卯 Guǐ Mǎo |
| 戊 Wù | 乙卯 Yǐ Mǎo |
| 己 Jǐ | 丁卯 Dīng Mǎo |
| 庚 Gēng | 己卯 Jǐ Mǎo |
| 辛 Xīn | 辛卯 Xīn Mǎo |
| 壬 Rén | 癸卯 Guǐ Mǎo |
| 癸 Guǐ | 乙卯 Yǐ Mǎo |
Notice the pairs: year stems 甲/己, 乙/庚, 丙/辛, 丁/壬 and 戊/癸 share columns under the Five Tigers rule, which is why ten year stems produce only five distinct Rabbit pillars. The full grid for every month sits in the master month stem table.
What the Rabbit month does to a chart
Mao is the peak of spring, and its Wood is the purest in the whole cycle. Unlike the Tiger, the Rabbit branch carries no hidden Fire and no hidden Earth: it is a single concentrated charge of Yi Wood, warmer and denser than the month before. That purity makes its effect sharp. A Wood Day Master born here is strongly rooted and can easily tip into being too strong. A Fire Day Master draws steady resource from the Wood and grows well. Earth is heavily controlled and reads weak, often needing help elsewhere. Metal is deep out of season and struggles. Water pours its strength into the Wood and thins out.
One thing we watch for in a Rabbit month is that pure Wood can crowd a chart: when Wood is this dense it may need a little Metal to prune it or Fire to draw it out, or it grows lush without producing anything. If your Day Master is Yi or Jia Wood, pair this with Yi Wood born in spring for the fuller seasonal reading. For any other stem, treat the month as the baseline temperature only; the final judgement of strong versus weak Day Master still depends on all four pillars working together.
Every element’s state in the Rabbit month
Practitioners grade the season’s effect through the five states (旺相休囚死 wàng xiàng xiū qiú sǐ). The Rabbit sits at the centre of spring: Spring = Wood season, branches 寅卯辰, Feb 4 – May 4 (from Li Chun 立春 to before Li Xia 立夏). In this month the five elements read as follows.
| Element | State | What it means here |
|---|---|---|
| Wood | 旺 wàng — Prosperous | The season is your own element: maximum native strength; the chart usually needs outlets, not more support |
| Fire | 相 xiàng — Supported | The season feeds your element: strong by backing; comfortable, resourced, sometimes over-sheltered |
| Water | 休 xiū — Resting | Your element feeds the season: energy flows out; mild drain, the retired-general state |
| Metal | 囚 qiú — Confined | Your element controls the season: fighting uphill against the times; effortful, gritty |
| Earth | 死 sǐ — Dormant | The season controls your element: weakest baseline; support and timing matter more than effort |
Because Mao is the season’s peak rather than its opening, these states run at full intensity here: the Prosperous is at its most prosperous and the Dormant at its most dormant. The other pillars then confirm or contradict that baseline.
What sits inside the branch
The Rabbit branch is the simplest of all: it hides only Yi Wood, with no secondary stems to soften or complicate it. The verbatim listing is short: Mǎo 卯 (Rabbit): Yǐ 乙 (Yin Wood), and that single stem is also the main qi (本气 běnqì). That is why Mao behaves so single-mindedly. See the Mao branch hidden stems for how that single charge is read in practice.
Locating your Rabbit-month pillar
Open your chart and read the month column. The branch should be 卯 for any birth between Jing Zhe (~6 March) and Qing Ming (清明 Qīngmíng, ~5 April), the term that opens the Dragon month. Then confirm the stem against the table above using your year stem — and remember the year stem is the Ba Zi year’s stem, which changed at Li Chun in early February, not at New Year. A birth in a 丙 year, for example, must show 辛卯, and you can verify the whole column in the Bing-year month stem table. If your calculator shows anything else, the year stem or the boundary has been misjudged.
The month palace
As the palace of career climate and of parents, a Rabbit-month pillar often points to a refined, growth-minded early environment: things that mature steadily rather than force their way. Read it as the season your working life was set in, not a fixed outcome. Compared with the neighbouring Tiger month, the Rabbit is warmer and less restless; the following Dragon month then hands spring over to damp earth and closes the season.
Common questions about the Rabbit month
Does a Rabbit month automatically make a Wood Day Master strong?
It gives Wood the strongest possible seasonal baseline, but not an automatic verdict. A Yi Wood Day Master surrounded by Metal and Fire in the other pillars can still be judged weak overall. The month is the largest single vote, not the whole election.
Why does the Rabbit clash with the Rooster?
In the fixed Six Clashes (六冲 liùchōng) list, 卯↔酉 stand opposite each other. If your chart carries a 酉 elsewhere, it clashes into the month palace, which practitioners read as disruption around career climate or the parental home, judged case by case.
I was born on 4 March. Which month am I?
Almost certainly still the Tiger month, since Jing Zhe usually falls around 6 March, but the exact hour of the term moves year to year. Plot the birth in the calculator and let the true solar-term time decide.
