Preserve the original record

Keep the supplied local date, time, place description, and precision notes separate from normalized values. An unknown time is not midnight. An approximate recollection is not a measured confidence interval. These distinctions should remain understandable throughout the workflow.

Make normalization traceable

Location matching and time-zone resolution are decisions that can need correction. Preserve the selected place, zone, normalized instant, and assumptions. A later correction should make clear which dependent results were recalculated rather than leaving old interpretations attached to a new chart.

Show what missing time changes

Decide which requested outputs are unavailable when birth time is unknown. Do not fill a reserved visual space with a made-up ascendant or house placement. A schematic chart can still be useful when it is clearly labeled as an illustration rather than a personal calculation.

Build with synthetic fixtures first

Test ordinary records, ambiguous places, unknown times, and clock-change edge cases before collecting real information. This site demonstrates structures without collecting birth data. The complete article explains the input pipeline, while the chart guide focuses on presenting the resulting settings and warnings.

A focused reading path

Begin with Natal Chart API: Why Birth Time and Data Quality Matter. Then review the local response examples and use the glossary for unfamiliar terminology. The examples help plan a product; they do not provide an operational service.
