Place becomes time
Local city search resolves an IANA time zone, historical offset, and the longitude needed for optional True Solar Time.
Read the structure. Keep the mystery honest.
MingWeave turns your birth time and place into a clear BaZi chart, then shows the time rules and boundaries behind every pillar.

A chart should show its working.
Two calculators can disagree because they chose different time, day-boundary, or solar-term rules. MingWeave keeps those choices attached to the result instead of hiding them behind a verdict.
Boundaries stay visible
Li Chun, monthly Jie, midnight, Zi hour, and daylight-saving edges produce explanations rather than silent guesses.
Your details stay local
During P0, birth details are calculated in your browser and are not saved to a MingWeave account or database.
Complex rules, ordered for a first reading.
Start with your Four Pillars and Day Master. Then move through Five Elements, Hidden Stems, Ten Gods, interactions, and Luck Pillars at your own pace. Technical evidence remains one disclosure away.
