Description
Parse a supplied weeks-plus-days research token.
Pregnancy and birth research records distinguish observed and estimated values, dating anchors, day coordinates, time precision, clock offsets, and source permissions. A notation conversion or interval comparison does not determine a clinical date or validate consent. The supplied reference convention and uncertainty need to remain visible.
Parse a supplied weeks-plus-days research token.
When to use this tool
Use Obstetric Research Gestation Weekday Token when you need this supplied research age, date, interval, clock, provenance, or record-rule calculation.
How to use the tool and how it works
- Enter token. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read weeks, days, totalDays. Use the output convention below.
Accept a nonnegative whole-week token without redundant leading zeros, a plus sign, and one day digit from zero through six. Return weeks, days, and totalDays=weeks*7+days.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Whole weeks plus one day digit, such as 12+3; days range zero through six. | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| weeks | Weeks | Required. Safe integer. |
| days | Days | Required. Safe integer. |
| totalDays | Total Days | Required. Safe integer. |

}Limitations and assumptions
- This is notation conversion, not determination of gestational age, a clinical plausibility check, or a week-specific care recommendation. Very large total-day results outside the safe integer range are rejected.
- 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.
Alternative or Complementary methods
Use verified dates and sources together with the intended research or clinical assessment process. Check dating anchors, clock conventions, uncertainty, and whether a supplied reporting rule is appropriate for the question.
