Description
Subtract exclusions within observedMinutes for denominatorMinutes, validating validMinutes within that remainder.
Personal health and activity records use supplied observations, labels, and time intervals. A formatter or simple summary can organize those records without assessing health, diagnosing a condition, or recommending treatment.
Subtract exclusions within observedMinutes for denominatorMinutes, validating validMinutes within that remainder.
When to use this tool
Use Diary Day Valid Time Share when you need a bounded personal-record calculation with explicit units and date conventions.
How to use the tool and how it works
- Enter validMinutes, observedMinutes, excludedObservedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominatorMinutes, share, defined. Inspect defined before interpreting the associated values.
Subtract exclusions within observedMinutes for denominatorMinutes, validating validMinutes within that remainder. Return valid/denominator or zero with defined false for no eligible time.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| validMinutes | Valid Minutes | Required. Finite number; minimum 0. |
| observedMinutes | Observed Minutes | Required. Finite number; minimum 0. |
| excludedObservedMinutes | Excluded Observed Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominatorMinutes | Denominator Minutes | Required. Finite number. |
| share | Dimensionless share under the stated denominator and exclusion convention. | Required. Finite number. |
| defined | Whether the associated ratio has its required denominator; inspect before using a zero placeholder. | Required. Boolean. |

}Limitations and assumptions
- Validity flags and durations are supplied; zero share can be undefined and no clinical validity, device accuracy, or missing-time correction is established.
- 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 original observations and consult an appropriate health professional for clinical interpretation or care decisions.
