The year formula and number 5
Reduce the digits of the full solar birth year to one digit. Male branch: reduce 11 minus that digit. Female branch: reduce 4 plus that digit. If the result is 5, use 2 for the male branch or 8 for the female branch. This full-year formula handles the 1999 / 2000 transition without a last-two-digit shortcut.
What do the four directions mean?
Sheng Qi, Tian Yi, Yan Nian and Fu Wei are traditional Eight Mansions categories, often translated as growth, health, harmony and stability. Here they are historical labels; facing a direction does not guarantee health, wealth, love or safety.
Solar-term boundaries are computed estimates. A displayed second is calculation precision, not a certified birth-record measurement. Confirm a birth time within one minute of the boundary with a specialist.
