Description
Quote date text and append its declared precision.
Archival records often contain bounded dates, editions, and source identifiers. Arithmetic on supplied coordinates can check consistency while leaving historical interpretation and authenticity unresolved.
Quote date text and append its declared precision.
When to use this tool
Use Historical Event Date Precision Token when you need a precise date-span or source-record bookkeeping step.
How to use the tool and how it works
- Enter eventId, dateText, precision. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read token. Use the output convention below.
Require nonempty eventId and dateText and a listed precision token. Quote date text and append its declared precision.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| eventId | Event Id | Required. Text; maximum UTF-16 length 8192. |
| dateText | Supplied date text under the accepted precision and grammar above. | Required. Text; maximum UTF-16 length 8192. |
| precision | Recorded precision category; not a measurement-uncertainty estimate. | Required. Text; one of "exact-day", "month", "year", "circa", "range", "unknown"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| token | Token in the supported spelling; inspect the accepted grammar above. | Required. Text; maximum UTF-16 length 8192. |

{
"input": {
"eventId": "E7",
"dateText": "1750",
"precision": "circa"
},
"output": {
"token": "E7; date=\"1750\"; precision=circa"
}
}Limitations and assumptions
- This records uncertainty metadata without parsing the date, estimating an interval, normalizing a calendar, or verifying an event.
- 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 catalog and documented calendar or dating convention when historical interpretation matters.
