Chronological Invariants and the Saturnian Audit: A Structural Analysis of the 297-Year Temporal Displacement and the Antediluvian Sovereign Calendar v2 AuthorsAllan Christopher Beckingham, CDhttps://orcid.org/0009-0004-2830-4089 AffiliationIndependent Researcher(Coherence Dynamics Laboratory / Virtual Ego Framework) Date:5 February 2026 AD (Gregorian surface date)/14 Janos -1 ASCInternal Alignment: 1729 AD Resonance (analytical reference only) LicenseCreative Commons Attribution 4.0 International (CC BY 4.0) Abstract / Description This work presents a comprehensive analytical audit of Western chronological records using astronomical, architectural, and calendrical invariants as stress-testing constraints. Building on prior scholarship surrounding the Phantom Time Hypothesis, the paper evaluates a constant-offset re-indexing model (Model A: −297 years) as a hypothetical analytical instrument for identifying strain between medieval historical narratives and independent physical telemetry. Rather than asserting a correction to civil or legal timekeeping, the study explicitly frames Model A as an interpretive stress test applied to historical records. The approach compares legacy chronologies against immutable astronomical references—most notably Saturn’s orbital periodicity (~29.46 years) and documented solar eclipse path descriptions—to determine whether specific medieval dates align coherently with high-precision ephemerides. The analysis identifies recurring discrepancies in eclipse reports, planetary conjunctions, and material culture (e.g., architectural stasis and spolia reuse) clustered around the early medieval period traditionally dated to AD 614–911. When examined under a constant-offset model, several of these discrepancies exhibit improved coherence with physical constraints, suggesting potential calendar migration errors, retrospective narrative construction, or administrative compression in the historical record. To contextualize these findings, the paper integrates the Antediluvian Sovereign Calendar (ASC) - https://doi.org/10.5281/zenodo.18368598 —a mechanically coherent civil timekeeping system based on a fixed 13 × 28-day lattice (364 days) with solar reconciliation handled via external boundary days (Alpha and Omega). The ASC is presented not as a replacement for the Gregorian calendar but as a structural comparator, demonstrating how invariant lattice calendars eliminate weekday drift and cumulative leap-year distortion. Extensive annexes provide side-by-side mappings of selected historical events under legacy Gregorian dates and Model A re-indexing, clearly labeled as illustrative rather than corrective. Additional appendices document leap-handling mechanics, astronomical constraint methodology, and interpretive scope limitations to ensure academic clarity and auditability. Overall, the paper offers a rigorously scoped framework for chronological stress testing, positioning astronomical invariants as neutral arbiters where historical records appear internally strained. It is intended as a contribution to interdisciplinary dialogue among historians, astronomers, chronologists, and systems theorists concerned with long-baseline temporal coherence. Key Contributions Introduces a non-antagonistic, hypothesis-scoped model for testing medieval chronologies against astronomical constraints Demonstrates how Saturnian orbital periodicity functions as a long-baseline chronological invariant Provides a mechanically consistent lattice-based civil calendar (ASC) for comparative analysis Separates observational data from interpretive modeling, preserving institutional admissibility Supplies extensive annexes with transparent assumptions and reproducible mappings Interpretive Scope Notice All calendar re-indexing and alternative year mappings presented herein are explicitly hypothetical and analytical in nature. No claim is made that the present year, civil dates, or legal timekeeping differ from the Gregorian standard. The Antediluvian Sovereign Calendar is evaluated solely as a mechanically coherent civil calendar model and comparative analytical framework.Keywords#chronology, #phantom_time_hypothesis, #calendar_reform, #historical_chronology, #astronomical_dating, #saturn_orbital_period, #solar_eclipses, #medieval_history, #julian_calendar, #gregorian_calendar, #timekeeping_systems, #chronological_modeling, #civil_calendars, #lattice_calendar, #systems_theory, #structural_invariants, #historical_methodology, #interdisciplinary_research, #temporal_analysis, #calendar_drift, #ephemerides
