Description
Subtract omittedDays from labelDifference and add repeatedDays for elapsedDays.
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.
Subtract omittedDays from labelDifference and add repeatedDays for elapsedDays.
When to use this tool
Use Calendar Gap Duration Correction when you need a documented calendar convention or source-coordinate comparison.
How to use the tool and how it works
- Enter labelDifference, omittedDays, repeatedDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read elapsedDays. Use the output convention below.
Require nonnegative integer omittedDays and repeatedDays. Subtract omittedDays from labelDifference and add repeatedDays for elapsedDays.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| labelDifference | Label Difference | Required. Safe integer. |
| omittedDays | Omitted Days | Required. Safe integer; minimum 0. |
| repeatedDays | Repeated Days | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| elapsedDays | Elapsed Days | Required. Safe integer. |

}Limitations and assumptions
- All inputs share a day basis; transition details are supplied rather than drawn from jurisdictional calendar history and the signed result is not a verified date difference.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult the source calendar and authoritative date information for actual observance, conversion, or historical dating.
