Description
Add it to issuedDay, subtract queryDay for remaining time and flag expired only after expiry.
Food-safety records connect lots, samples, tests, labels and handling events. Consistent identifiers and reconciled quantities support record review, but do not establish safe food, complete traceability or valid regulatory approval.
Add it to issuedDay, subtract queryDay for remaining time and flag expired only after expiry.
When to use this tool
Use Food Inspection Record Expiry Gap when you need a specified food-handling record or traceability diagnostic.
How to use the tool and how it works
- Enter issuedDay, validityDays, queryDay. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expiryDay, remainingDays, expired. Inspect expired before interpreting the associated values.
Require nonnegative integer validityDays. Add it to issuedDay, subtract queryDay for remaining time and flag expired only after expiry.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| issuedDay | Issued Day | Required. Safe integer. |
| validityDays | Validity Days | Required. Safe integer; minimum 0. |
| queryDay | Query Day | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expiryDay | Expiry Day | Required. Safe integer. |
| remainingDays | Remaining Days | Required. Safe integer. |
| expired | Expired | Required. Boolean. |

}Limitations and assumptions
- Expiry equality is accepted. This arithmetic does not authenticate an inspection or establish legally valid approval, acceptable conditions or safe food.
- 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
Review the complete controlled records, actual product condition and applicable validated procedures. Authenticate sources and approvals rather than treating one matching token or balance as a safety verdict.
