Tool Notes
The Year Pillar is based on Start of Spring, the Month Pillar on solar terms, the Day Pillar on Julian day calculation, and the Hour Pillar on the day stem.
Lunar input is first converted to Gregorian, then used for Four Pillars charting; leap months appear automatically by year.
Luck Pillars run forward for yang men/yin women and backward for yin men/yang women, with the start time converted from adjacent solar terms.
Solar term transitions, late Zi hour, and true solar time can affect results; verify if birth time is near a boundary.
