Output

Example use cases
Birth chart for astrology reading
“Generate the full BaZi Four Pillars chart for someone born on July 22, 1985 at 08:15 AM in China (UTC+8) — I need the stems, branches, zodiac animals, five-element counts, and day master for a Chinese astrology reading.”
Auspicious date analysis
“What are the heavenly stem and earthly branch pillars for January 8, 2025? I want to check the five-element energies of that day to see if it's auspicious, using midnight as the day start.”

Endpoint
GEThttps://chinese-culture.x402tookit.com/bazi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable BaZi / Four Pillars data including stems, branches, animals, five-element counts, and day master for a specific Gregorian date and optional time. It is more suitable than a general Chinese calendar lookup when the use case is Chinese metaphysics, astrology, feng shui, or destiny analysis rather than simple lunar date conversion. It covers dates from 1930 to 2100 and supports configurable UTC offsets and day-start conventions (midnight or 23:00) for different BaZi schools.
Side effects
- Date out of supported range (1930–2100) returns an error
- Malformed date format (not YYYY-MM-DD) causes a validation error
- Invalid time format (not HH:MM) causes a validation error
- UTC offset outside -12 to 14 returns a validation error
- Hour pillar omitted if time parameter is not supplied (expected behavior, not a failure)
- Network or payment errors may return 402 or 5xx responses
