Without birth time
You can still learn from the Day Master, broader chart structure, and date-based pattern teaching. This is enough for a light preview.
Birth time
Why birth time matters.
Birth time matters because it gives the chart its hour pillar. Without it, the reading can still be useful at a surface level, but it loses part of its structural detail and some timing precision. That is why serious platforms keep asking for time once users want depth.
Practical explanation
Surface reading vs full reading.
With birth time
The chart becomes fuller. That helps with detailed timing, deeper structure, and stronger personalized reports.
Why products ask later
Good products do not demand everything upfront. They let the user see value first, then explain why missing birth time limits depth.
Best next step
Use the light layer first, then add precision when you want depth.
