Description
Test start-inclusive/end-exclusive membership, allowing wrap across midnight; equal endpoints define an empty window.
Personal health logs distinguish clock coordinates, elapsed durations, pauses, and missing time metadata. A supplied time comparison organizes records without measuring an activity or assessing its health effects.
Test start-inclusive/end-exclusive membership, allowing wrap across midnight; equal endpoints define an empty window.
When to use this tool
Use Health Diary Safe Contact Time Window when you need one explicit diary-duration or clock-accounting component.
How to use the tool and how it works
- Enter minuteOfDay, start, end. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inside, wrapsMidnight. Inspect inside, wrapsMidnight before interpreting the associated values.
Require minuteOfDay, start, and end in 0-1439. Test start-inclusive/end-exclusive membership, allowing wrap across midnight; equal endpoints define an empty window.1

}Limitations and assumptions
- A supplied contact window is not verified consent or a guarantee that contact is safe; timezone, daylight-saving transitions, and emergency handling are outside the calculation.
- 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
Retain dates and offset information and consult an appropriate professional for questions about health, care, or suitable activity.
