Xiaodao

Xiaodao gives Claude accurate Chinese metaphysics charts to work from. Xiaodao calculates; Claude interprets.

What it does

• Bazi (Four Pillars): the four pillars with hidden stems and ten gods, lunar date, month command, luck start and direction, all twelve ten-year luck cycles with their years, and the annual, monthly, daily and hourly pillars for any focus date.
• Qimen Dunjia: hour charts by the chai bu method with the rotating plate, nine palaces laid out.
• True solar time: converts a historical local clock time at a birth place to true solar time, removing daylight saving and applying longitude and the equation of time.
• Birth place search: places with coordinates and historical time zone rules, in Chinese and English.

Why it matters Charts go wrong when time zones, daylight saving or solar-term boundaries are handled loosely. Xiaodao uses each place's historical time zone rules (China's daylight saving years 1986-1991 included), true solar time for the day and hour pillars, and the actual solar-term instant for the year and month. When a birth time falls on a boundary or a repeated clock hour, it asks you to choose instead of guessing. Supported dates run from 1801 to 2099.
