《黄帝内经·灵枢·阴阳系日月》
戌纪九月，主身体右侧下肢的足厥阴肝经；亥纪十月，主身体左侧下肢的足厥阴肝经，九、十月是秋冬交接之时，阴气由弱到盛完成转化交接，所以称为厥阴。
戌者，九月，主右足之厥阴；亥者，十月，主左足之厥阴，此两阴交尽，故曰厥阴。
The ninth month of Xu Ji governs the Foot Jueyin Liver Meridian on the right lower limb; the tenth month of Hai Ji governs the Foot Jueyin Liver Meridian on the left lower limb. September and October are the time when autumn and winter meet, and yin qi completes the transition from weak to strong, so it is called jueyin.
