Validated Calculation and Candidate Selection in Birth Time Rectification
Numji's Birth Time Rectification infrastructure was examined through astronomical references, independent score calculations, and comprehensive time scanning across 100 test cases generated from various birth dates, time ranges, geographical locations, house systems, and controlled life event clusters. A total of 10,200 results were analyzed.
Candidate times' axes and house calculations, event signals, score and coverage formulas, coarse–fine scanning, confidence levels, event clustering, and result ranking passed the established acceptance criteria. The time selected by the normal search matched the global maximum of the 20-second complete scan in every single case.
Validated Rectification calculations
The primary groups of astronomical, temporal, and decision layers that evaluate candidate birth times from life events.
CANDIDATE TIMES AND ASTRONOMICAL FOUNDATION
Each candidate's local and UTC time, ASC–MC values, and twelve house cusps were compared against astronomical references across different locations and house systems.
COARSE AND FINE SEARCH
Candidates advanced by the coarse scan to refinement were independently compared with the global maximum from a complete 20-second scan of the same interval.
EVENT SIGNALS AND SCORING
Transit, secondary progression, and Solar Arc signals were recalculated using rules for aspect, orb, technical diversity, axis sensitivity, event significance, and date uncertainty.
RANKING AND CONFIDENCE LEVEL
Raw and normalized scores, event coverage percentage, minimum time separation between candidates, confidence level, and result rankings were checked.

How was the global maximum validated?
The goal was to compare the normal usage workflow not only against its own results, but against a complete reference scan of the same interval.
NORMAL SEARCH
The engine first evaluated coarse candidates using designated minute steps; it then refined the strongest regions using second-level steps to construct the result list.
COMPLETE REFERENCE SCAN
All candidates within the same time interval were scanned using 20-second steps. The best time and score found by the normal search matched the global maximum of the complete scan across all 100 cases.
Test methodology
The goal was to ensure results rely on diverse times, locations, house systems, and decision conditions rather than a single individual or event cluster.
SCOPE
- 100 distinct rectification cases
- Various birth dates, locations, and house systems
- Six controlled life events per case
- Total of 10,200 comparisons
TRIPLE-TECHNIQUE SCORING
- Transit indicators
- Secondary progressions
- Solar Arc indicators
- Independent signal and axis sensitivity control
DECISION RULES
Event significance, date uncertainty, event clustering within 180 days, technical diversity, time-sensitive axis evidence, candidate separation, and confidence level were independently recalculated.
INDEPENDENT CALCULATION
Astronomical references and complete scanning were used strictly for comparison purposes. Numji's production calculations are executed within its own calculation infrastructure independently of the validation tool.
What does this result mean for the astrologer?
The axes, houses, life event signals, scores, and rankings of candidate times evaluated during a rectification study are delivered through a verified calculation infrastructure. Thanks to the accuracy of the coarse–fine search, the risk of missing strong candidates within the time window is minimized. Results should still be approached alongside documentary event dates, client narrative, and independent astrological evaluation.
