Description

Preserve explicit early-date text and supplied year-numbering convention.

Historical records separate source readings, remembered dates, documentary dates, place identifiers and editorial conventions. Supplied certainty or witness labels are annotations rather than authenticated evidence. Original spellings, calendar styles and accession-year conventions need their documentary context before chronological interpretation.

Preserve explicit early-date text and supplied year-numbering convention.

When to use this tool

Use Calendar Date Before Year Zero Source Label when you already have recordId, suppliedDateText, yearNumberingConvention and need to preserve explicit early-date text and supplied year-numbering convention.

How to use the tool and how it works

  1. Enter recordId, suppliedDateText, yearNumberingConvention. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read token. Use the output convention below.

Enter recordId, suppliedDateText, yearNumberingConvention using the field constraints below. Encode these values, in exactly that order, as a JSON array and return the serialized array as text in token. String values are preserved without trimming or external terminology lookup.1

Limitations and assumptions

  • The result records supplied values without inserting year zero or converting calendars. Sources and asserted relationships are not independently authenticated.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Consult the original source, edition and provenance for a historical claim. Apply an appropriate calendar or documentary analysis when actual conversion, identity or interpretation is needed; a transcription key or uncertainty marker does not establish those results.
