Charts you can compute
Every chart below is produced by a rule engine — same input, same output, every time. That is why charting is free and always will be: it costs us almost nothing to run.
Why charting is free
Bazi, Four Pillars and element weighting are deterministic calculations. There is no model guessing at them, and no per-request cost to us beyond a few milliseconds of CPU. Since the cost is near zero, the price is too.
AI interpretation is different. Each request has a real cost, so it is metered — and we show you the count before you spend it, not after.
What each tool does

The calculation basis is always shown
Most tools in this category hide how they resolved your birth time. We show it: the IANA time zone applied, whether daylight saving was in effect, the calendar used, and whether true solar time was enabled.

Birth data is never placed in a URL. Personal result pages carry a noindex directive and are excluded from the sitemap. Shared cards are redacted by default and never contain your full birth date.
