Zi Wei Timing and Period Layers
Learn Zi Wei timing through reproducible decade-to-hour records, explicit overlays, boundary policies, and cautious observation windows.
Overview
This timing hub keeps natal, decade, annual, monthly, daily, and hourly evidence separate. It links calculated periods back to the chart and turns symbolic timing into bounded observation windows rather than promised events.
At a glance
- Canonical scope
- Nine new owners cover decade calculation, Minor Limit, annual systems, Dou Jun and months, daily and hourly layers, overlays, empty-palace timing, and precision bias.
- Required evidence
- Every timing record preserves layer, period key, boundary, source rule, palace, resident evidence, and transformation provenance.
- Reading method
- Verify the natal chart, calculate one timing layer at a time, preserve parent layers, compare only explicit correspondences, and record misses as well as apparent matches.
- Boundary
- Timing narrows a context for observation; it does not validate event prediction, exact dates, or hindsight-based certainty.

This timing hub keeps natal, decade, annual, monthly, daily, and hourly evidence separate. It links calculated periods back to the chart and turns symbolic timing into bounded observation windows rather than promised events.
- Verify the chart and source before interpreting.
- Return every claim to an observable question or safe limit.
Evidence requirements
Every timing record preserves layer, period key, boundary, source rule, palace, resident evidence, and transformation provenance.
