When evaluating Tiger (寅) and Snake (巳) in authentic Four-Pillar synastry (合婚), classical practitioners inspect which natal palace hosts the 寅–巳 vector (Six Harm Calibration (六害) · 寅巳相害兼三刑). 寅 governs the 1st Lunar Month (Start of Spring · 立春) command (03:00 – 04:59 (Dawn Threshold), East-Northeast (60°), Six-Harmony ally Pig 亥), whereas 巳 anchors the 4th Lunar Month (Start of Summer · 立夏) command (09:00 – 10:59, South-Southeast (150°), Six-Harmony ally Monkey 申).
Across the 12-branch ecliptic wheel, 寅 (#3) and 巳 (#6) sit 3 steps apart, creating a 65% baseline resonance between Yang Wood (Yin Tiger (寅虎) — The Vernal Sovereign & Furnace of Fire) and Yin Fire (Si Snake (巳蛇) — The Alchemical Strategist & Birthplace of Metal).
