Description
Require nonempty dateText, calendarName, and source and format a source-qualified calendar label.
Calendar coordinates depend on an era, origin, day-start rule, and sometimes an arithmetic rather than observational convention. A supplied coordinate difference does not resolve those choices.
Require nonempty dateText, calendarName, and source and format a source-qualified calendar label.
When to use this tool
Use African Document Calendar Source Label when you need a documented calendar convention or source-coordinate comparison.
How to use the tool and how it works
- Enter dateText, calendarName, source. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.

{
"input": {
"dateText": "12/3/1340",
"calendarName": "source calendar",
"source": "Document A"
},
"output": {
"label": "12/3/1340 [source calendar; Document A]"
}
}Limitations and assumptions
- The date is neither parsed nor converted; historical variants, precision, and calendar equivalence are not determined.
- 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 source calendar and authoritative date information for actual observance, conversion, or historical dating.
