Astronomical Axis Year — a linear chronology coordinate system derived from astronomical reference alignment within the OSTARA-3339 cosmological time architecture.
The Astronomical Axis Year (AAY) is a linear chronological coordinate system designed to represent time relative to a defined astronomical reference framework within the OSTARA-3339 protocol.
It serves as the primary numerical representation layer for converting astronomical alignment states into structured temporal values.
AAY is derived from the relationship between Earth’s axial orientation and a chosen astronomical reference frame defined in the OSTARA Astronomical Model layer.
The system expresses time as a continuous coordinate rather than a discrete civil calendar epoch.
CORE defines invariant principles and structural constraints. AAY is a derived representation system operating within those invariants.
Changes to astronomical models do not alter CORE definitions but may affect interpretative mapping of AAY values across epochs.
AAY is designed to remain continuous across civilisational transitions, ensuring that chronological data remains interpretable even under changes in astronomical reference points or observational frameworks.
AAY depends on the Astronomical Model for reference alignment but does not require a single fixed stellar anchor. This ensures adaptability in multi-planetary or long-duration contexts.
AAY values are expressed as continuous numeric coordinates representing position within the OSTARA temporal axis. The exact encoding rules are defined in the Specification layer.
AAY is designed to interoperate with ISO-8601, RFC3339, Unix time, and Julian Date systems through deterministic conversion functions.
