Description
Calculate signed remaining time in a supplied supervised-play session.
Developmental records distinguish calendar age, supplied age corrections, observation states, assent and privacy choices. A corrected age can be negative under supplied assumptions, and a missing response differs from an observed zero. A display mask changes presentation without protecting the underlying record.
Calculate signed remaining time in a supplied supervised-play session.
When to use this tool
Use Supervised Play Session Duration Remaining when you already have plannedMinutes, elapsedMinutes and need to calculate signed remaining time in a supplied supervised-play session.
How to use the tool and how it works
- Enter plannedMinutes, elapsedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read remainingMinutes. Use the output convention below.
Require planned/elapsed minutes>=0; return planned-elapsed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| plannedMinutes | Planned Minutes | Required. Finite number; minimum 0. |
| elapsedMinutes | Elapsed Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| remainingMinutes | Remaining Minutes | Required. Finite number. |

}Limitations and assumptions
- Overruns give negative output. No actual supervision, safety, fatigue, session suitability or developmental need 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
Use the complete observation or assessment method, age convention and consent context. Review source records and data protection together; local counts, labels and geometric measurements do not establish development, diagnosis or appropriate support.
