Notes
The year pillar is defined by Lichun (Start of Spring) and the month pillar by solar terms, consistent with traditional almanacs; the Chinese zodiac follows the year pillar (changes at Lichun). Auspicious/inauspicious activities and spirit information are based on traditional almanac algorithms and are for cultural reference only, not for decision-making.
