小滿 Lesser Fullness: summer solar term, May 20-22 小滿 · Xiǎo Mǎn

Classical attributes

• Solar position: longitude 60°
• Date range: May 20-22
• Season: summer (early summer)
• Type: 氣 — Mid-term — within month
• Month branch: 巳 (Snake)

Climatic register

Grain is plump but not yet ripe — 'lesser fullness' rather than completion. The fire-element energy strengthens but has not reached its peak; preparation for the full heat of midsummer.

Hidden stems of the 巳 month branch

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

• 丙 (Yang Fire, primary)
• 庚 (Yang Metal, transitional)
• 戊 (Yang Earth, residual)

BaZi relevance

小滿 is the mid-term within the 巳 month pillar. The classical 'lesser fullness' period reads as the consolidation phase of early summer — where the fire-element register that opened at 立夏 stabilises before the deeper heat of 芒種 and 夏至.

QMDJ (Qi Men Dun Jia) relevance

Same as 穀雨 — yang dun 5 (centre / self-position) opening, transitioning into 2 (illness) and 8 (accumulation). In the QMDJ system, 小滿 falls within the 陽遁 (yang dun, forward-rotating expansion) half-year. The three thirds of this solar term map to 陽遁5局 (upper), 陽遁2局 (middle), and 陽遁8局 (lower) respectively. QMDJ consultations made during 小滿 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 小滿, see the 18 Dun Periods reference for the relevant dun-period pages, or book a QMDJ forecasting consultation.

Observed register for 小滿 births

小滿 carries the register of partial achievement — almost-full but consciously not-quite-yet, leaving room for further growth. Born around 小滿 often carries a register of pacing, knowing when to consolidate rather than push.

Why generic Lesser Fullness interpretation fails

The solar term is one structural layer of a BaZi chart, not the whole chart. The actual reading for someone born around 小滿 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 小滿 (May 20-22). For BaZi practice, this mid-term sits within the 巳 month pillar without changing it.
• Read the 小滿 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 小滿 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.
