Description
Include both window endpoints, wrapping across cycle end when start>end; return nonnegative modular days to start.
Policy-related period and quantity calculations need explicit expiry boundaries, claim-season anchors and moisture conventions. Half-open periods differ from inclusive day counts, and moisture-standardized mass differs from observed wet mass. Supplied rules and reference values do not establish current policy.
Include both window endpoints, wrapping across cycle end when start>end; return nonnegative modular days to start.
When to use this tool
Use Agricultural Tariff Season Window Gap when checking the stated caller-defined policy time, proration or material-basis convention.
How to use the tool and how it works
- Enter day, startDay, endDay, calendarDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read withinWindow, daysToStart. Inspect withinWindow before interpreting the associated values.
Require whole calendarDays 1..366 and day/start/end within 1..calendarDays. Include both window endpoints, wrapping across cycle end when start>end; return nonnegative modular days to start.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| day | Day | Required. Safe integer; minimum 1. |
| startDay | Start Day | Required. Safe integer; minimum 1. |
| endDay | End Day | Required. Safe integer; minimum 1. |
| calendarDays | Supplied whole cycle length 1..366; no civil calendar is selected. | Required. Safe integer; minimum 1; maximum 366. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| withinWindow | Within Window | Required. Boolean. |
| daysToStart | Nonnegative forward modular distance, zero at start even if the season is currently active. | Required. Safe integer. |

}Limitations and assumptions
- A cycle-day index is not a civil date; equal start/end selects one day rather than the entire calendar cycle.
- 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
Use verified dates, quantities and authoritative current program or contract documents for real administrative and financial decisions.
