Birth Time Calibration
Not sure of your birth hour? Compare charts of adjacent hours with checklist questions to narrow the range; if you know the four pillars, reverse-lookup the possible solar birth dates.
How it works
1. Enter birth data
Date, time, and birthplace are the only inputs for casting.
2. Deterministic engines compute
Charts and hexagrams are generated by rule-based programs and locked.
3. AI reads around your question
The reading stays anchored to your chart and your question; stop anytime.

Why no user counts or ratings?
The site has no verifiable public usage or review data yet, so the homepage shows usage scenarios instead of fabricated social proof.
Do I need to enter a real name?
No. The name is only used to address you in reports and never enters the calculation. Nicknames or blanks are fine.
What if the birth time is uncertain?
Use "Time Calibration" to compare adjacent hours with checklist questions and narrow the range before casting. If you know the four pillars, reverse-lookup the possible solar dates. Uncertain input should never be treated as fact.
What is the birth place used for?
It determines timezone (including historical DST) and longitude. BaZi day/hour pillars are corrected to true solar time (longitude + equation of time); astrology charts use coordinates for houses and the Ascendant. Without a city, Beijing time at 120° E is used.
