How to read this calendar
- Find the estimated conception date in the Gregorian date ranges. The columns follow lunar months, so they do not start on the first day of each Gregorian month. The first and last periods are limited to the selected calendar year.
- Use the mother’s nominal lunar age at conception: conception lunar year minus birth lunar year, plus one. Under this convention, age increases at Lunar New Year rather than on a birthday. The date-based calculator can work it out for you.
- Read the cell where that age row meets the conception-period column. The letter gives the result of the game; it does not give a probability.

Dates and method
This is the same 26-row chart used by our calculator, for nominal ages 18–43. Its historical origin is undocumented. A repeated lunar month uses the same result column as the regular month.
The Hong Kong Observatory publishes Gregorian–lunar conversion tables. They provide a reference for dates, not evidence for the gender chart.
