公历（阳历）以地球绕太阳公转为基础，农历（阴阳历）同时参考月亮绕地球的周期和太阳运行，通过闰月调整。农历是中国传统节日、占卜择日和命理学的基础。The solar (Gregorian) calendar is based on Earth orbiting the Sun. The Chinese lunar calendar combines both lunar months and solar terms, using leap months for adjustment. It is the basis for Chinese festivals, divination, and destiny analysis.

二十四节气是根据太阳在黄道上的位置划分的时间节点，每个节气约15天，反映季节变化和农事规律。它们在易经占卜和八字命理中用于确定月柱的起始。The 24 Solar Terms divide the year based on the Sun's position along the ecliptic, each lasting about 15 days. They reflect seasonal changes and are used in I Ching divination and Ba Zi to determine the start of monthly pillars.
