Description
Validate a real Gregorian date and startMinute in 0-1439, then serialize date, activity, and startMinute as a JSON-array key.
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.
Validate a real Gregorian date and startMinute in 0-1439, then serialize date, activity, and startMinute as a JSON-array key.
When to use this tool
Use Activity Log Manual Device Duplicate Key when you need a bounded personal-record calculation with explicit units and date conventions.
How to use the tool and how it works
- Enter date, activity, startMinute. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read key. Use the output convention below.
Validate a real Gregorian date and startMinute in 0-1439, then serialize date, activity, and startMinute as a JSON-array key.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| date | Gregorian date in the exact accepted precision and grammar. | Required. Text; maximum UTF-16 length 8192. |
| activity | Activity | Required. Text; maximum UTF-16 length 8192. |
| startMinute | Start Minute | Required. Safe integer; minimum 0; maximum 1439. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| key | Key | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"date": "2026-10-26",
"activity": "walk",
"startMinute": 480
},
"output": {
"key": "[\"2026-10-26\",\"walk\",480]"
}
}Limitations and assumptions
- Source type is intentionally absent from the key, but key equality alone does not prove duplicate activity or justify merging or deleting records.
- 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.
