Birth time unknown?
Keep the uncertainty visible.
Zi Wei Dou Shu uses a birth-time window for palace layout. If the time is uncertain, compare possibilities instead of pretending precision.
Birth time matters because traditional Zi Wei Dou Shu calculation uses it to anchor palace placement. A family memory such as “early morning” can still be useful, but it is not the same as an exact time on a record.
Start with the best evidence
Check a birth certificate, hospital record, family document, or a parent’s memory. Write down how certain the source is. If the answer could straddle two two-hour windows, keep both as candidates.
Compare, do not force a verdict
Generate the nearest plausible windows and compare the charts. Look for what stays stable before treating a difference as meaningful. A responsible reader says “this changes with the time assumption,” rather than using vague memory as false certainty.
Use the free chart lightly
When time is uncertain, let the chart be an exploratory tool: learn the palace language, note questions that resonate, and return to real evidence. Do not use a guessed window for high-stakes decisions.
