立冬 Beginning of Winter: winter solar term, November 7-8 立冬 · Lì Dōng

Classical attributes

• Solar position: longitude 225°
• Date range: November 7-8
• Season: winter (early winter)
• Type: 節 — Sectional term — month transition
• Month branch: 亥 (Pig)

Climatic register

First freezes; water dominates; the metal-element of autumn relinquishes ground to winter's water phase. Energy turns deeply inward; storage and rest dominate.

Hidden stems of the 亥 month branch

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

• 壬 (Yang Water, primary)
• 甲 (Yang Wood, transitional)

BaZi relevance

立冬 marks the transition into the 亥 (Hai, Pig) month pillar. The 亥 month is the early-water phase — yang water taking hold, with the wood that follows in spring already beginning to germinate beneath the surface.

QMDJ (Qi Men Dun Jia) relevance

Same as 寒露 — yin dun 6 opening, transitioning through 9 and 3. 立冬 marks the BaZi transition into the 亥 month pillar; QMDJ-wise, the yin-dun-6 register supports leadership consolidation as winter begins. In the QMDJ system, 立冬 falls within the 陰遁 (yin dun, backward-rotating consolidation) half-year. The three thirds of this solar term map to 陰遁6局 (upper), 陰遁9局 (middle), and 陰遁3局 (lower) respectively. QMDJ consultations made during 立冬 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 立冬, see the 18 Dun Periods reference for the relevant dun-period pages, or book a QMDJ forecasting consultation.

Observed register for 立冬 births

立冬 marks the decisive turn to inward focus, conservation, and quiet planning. Born around 立冬 carries a register of patient depth, the kind of reflective work that winter's stillness supports.

Why generic Beginning of Winter interpretation fails

The solar term is one structural layer of a BaZi chart, not the whole chart. The actual reading for someone born around 立冬 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 立冬 (November 7-8). For BaZi practice, this sectional term marks the month-pillar transition — births before vs. after the exact Beginning of Winter timestamp have different month pillars.
• Read the 立冬 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 立冬 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.
