What should a chart report do when the birth time is unknown?
It should preserve the stated date and place, define a defensible time interval, compute which features remain stable across that interval, and withhold unstable angles or houses. It should not convert noon, sunrise, or a rectified time into an observed fact merely because software requires one instant.
Direct answer
It should preserve the stated date and place, define a defensible time interval, compute which features remain stable across that interval, and withhold unstable angles or houses. It should not convert noon, sunrise, or a rectified time into an observed fact merely because software requires one instant.
Practical use
What to do with this answer
Publish a date- or interval-based stability result and label unavailable features explicitly. A later documented time can create a new calculation revision without rewriting the earlier uncertainty.
Distinctions to preserve
- Known date versus known instant
- Stable feature versus withheld feature
- Declared placeholder calculation versus historical evidence
Limitations
- Some fast lunar or angular features may vary substantially across a day.
- This procedure does not endorse any rectification technique.

Which existing contracts carry the answer
These linked pages carry the underlying definition, method, or tradition record and its own sources. This page preserves their boundaries rather than becoming a new source of independent authority.
Historical timezone uncertainty →
Establishes: Historical civil time is reconstructed evidence, not a timeless mapping. A database rule can be precise while the underlying historical record remains uncertain.
Boundary: Modern software precision cannot recover information absent from the historical record.
House-boundary sensitivity →
Establishes: A house label is a discrete classification derived from a house system; its stability depends on the distance from relevant cusps and on input uncertainty.
Boundary: Selecting a preferred house from several candidates after seeing outcomes is post-hoc model selection.
Date-only corporate chart stability audit →
Establishes: Calculate at the representative midpoint and both interval edges, sample intermediate instants where necessary, compare ascendant, whole-sign houses, and pañcāṅga limbs, and publish only features stable across the declared window.
Boundary: The method does not establish valuation, investment return, legal status, revenue, survival, market adoption, or a guaranteed business outcome, and it is not evidence that astrology predicts organizational events.
