FAQ
Common Questions
Does this page prove one exact birth minute is correct?
No. It tests whether the chart is stable enough across a narrow window to justify stronger exact-chart claims, which is a safer first step than pretending to know the answer immediately.
Why compare earlier and later windows instead of one chart only?
Because the real issue is fragility. Houses, angles, and the Rising sign can shift fast, so a stability check is more honest than treating one recorded minute as unquestionable.
When is this most useful?
Use it before publishing, trusting, or heavily interpreting a chart whose birth time may be rounded, estimated, or uncertain.
