Description
Parse a supplied era label and positive year suffix.
Language and manuscript records use explicit source labels, scripts, era-year conventions and text/area units. A literal split, Unicode slot or page-area calculation preserves supplied notation without resolving pronunciation, historical dates, manuscript identity or conservation needs.
Parse a supplied era label and positive year suffix.
When to use this tool
Use Public Era Year Token when checking the stated language, manuscript, era-label or Unicode convention.
How to use the tool and how it works
- Enter token, eraPrefix, separator. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read era, year. Use the output convention below.
Parse a supplied era label and positive year suffix. Require nonempty eraPrefix/separator and literal matching prefix; suffix must be nonzero decimal integer text convertible to a safe positive whole number.1
| Input field | Meaning and units | Accepted input |

| eraPrefix | Era Prefix | Required. Text; maximum UTF-16 length 8192. |
| separator | Separator | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |

"input": {
"token": "EraA-12",
"eraPrefix": "EraA",
"separator": "-"
},
"output": {
"era": "EraA",
"year": 12
}
}Limitations and assumptions
- Leading zero years are rejected; no historical era, calendar boundary or Gregorian conversion is independently resolved.
- 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
Inspect the original text/manuscript and its documented language, edition, calendar and encoding conventions for substantive linguistic, historical or conservation interpretation.
