Research focus
Record the original date, era system, region, precision and calendar source. Separate calendar conversion, time-zone conversion and method-specific boundaries.
02
Procedure and example
Retain alternate inputs near boundaries and identify whether uncertainty comes from records, conversion or disputed conventions.
03
Output and review
Deliver a complete conversion chain with source, intermediate values, convention and uncertainty so another reader can reconstruct it.
