雨水 Rain Water: spring solar term, February 18-20 雨水 · Yǔ Shuǐ

Classical attributes

• Solar position: longitude 330°
• Date range: February 18-20
• Season: spring (early spring)
• Type: 氣 — Mid-term — within month
• Month branch: 寅 (Tiger)

Climatic register

Snow gives way to rain; ice melts; the soil receives moisture for spring planting. The energy is gathering rather than asserting — preparation for the ploughing of spring.

Hidden stems of the 寅 month branch

The 寅 earthly branch holds these heavenly stems internally — read in BaZi as the “hidden essence” of the month pillar:

• 甲 (Yang Wood, primary)
• 丙 (Yang Fire, transitional)
• 戊 (Yang Earth, residual)

BaZi relevance

雨水 is the mid-term within the 寅 month pillar. It does NOT mark a month-pillar transition (those happen at the sectional terms). For BaZi practice, 雨水 is read as the strengthening / consolidation phase of the Yin month — the pioneering energy of 立春 settles into productive preparatory work.

QMDJ (Qi Men Dun Jia) relevance

The visibility-amplification register of yang dun 9 opens this term, transitioning into the authority register (6) and the eastward-movement register (3). In the QMDJ system, 雨水 falls within the 陽遁 (yang dun, forward-rotating expansion) half-year. The three thirds of this solar term map to 陽遁9局 (upper), 陽遁6局 (middle), and 陽遁3局 (lower) respectively. QMDJ consultations made during 雨水 carry the dun-period register stacked on top of the solar-term's seasonal energy.

For chart-aware QMDJ reading of a specific consultation made during 雨水, see the 18 Dun Periods reference for the relevant dun-period pages, or book a QMDJ forecasting consultation.

Observed register for 雨水 births

雨水 marks the gathering of resources before action — the receptive phase that follows the assertive opening of 立春. Born around 雨水 carries a quieter, more strategic register than 立春 — preparation, planning, taking in resources before deploying them.

Why generic Rain Water interpretation fails

The solar term is one structural layer of a BaZi chart, not the whole chart. The actual reading for someone born around 雨水 depends on the day pillar (the Day Master), the year and hour pillars, the chart's elemental balance, and the upcoming luck pillars. Generic per-solar-term descriptions can name the foundational seasonal register, but they cannot tell you what your specific chart says. Master Sean Chan’s BaZi consultation reads the full chart against your specific question.

• Identify whether your birth or your question's timing falls within 雨水 (February 18-20). For BaZi practice, this mid-term sits within the 寅 month pillar without changing it.
• Read the 雨水 register against your full chart. The solar term contributes a foundational layer; the rest of the chart determines actionable guidance.
• Plot your chart via the free BaZi Calculator to see how 雨水 interacts with your day, year, and hour pillars.
• Book chart-aware reading via BaZi consultation for high-stakes questions. Generic per-term reference is no substitute for the consultation.
