Chinese Gender Chart Calculator (Qing Palace Method)
Traditional Chinese Gender Predictor. Converts Gregorian dates to Lunar Age and Lunar Conception Month using a precise 1950-2040 calendar algorithm.
About
The Qing Palace Gender Chart is a statistical chart allegedly discovered in a royal tomb near Beijing. It relies on two specific variables: the Lunar Age of the mother at the time of conception, and the Lunar Month of conception. Unlike Western age, Lunar Age starts at 1 at birth and increments on the Chinese Lunar New Year.
Most online tools fail because they input Gregorian dates directly into the chart. This tool calculates the exact Lunar Age by comparing the mother's birth date to the Lunar New Year of her birth and conception years. It then maps the coordinates to the 336-cell matrix to reveal the traditional prediction.
Formulas
The lookup function G(a, m) is defined by the intersection of Lunar Age a and Lunar Month m.
