Lochia Duration Calculator
Actual elapsed start/end lochia calendar days, not expected duration, normal bleeding, treatment or permission to defer assessment of symptoms.
Description
Lochia duration compares a recorded onset date with a recorded endpoint.
Lochia duration compares a recorded onset date with a recorded endpoint.1
Calendar elapsed days differ from an inclusive count of both endpoint dates.
When to use Lochia Duration Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the observation date, units, measurement context and independently applicable clinical reference or calibrated model.
How to use Lochia Duration Calculator and understand its results
- Establish the observation date, units, measurement context and independently applicable clinical reference or calibrated model.
- Enter independentlyRecordedLochiaStartDate, independentlyRecordedLochiaEndDate, using the field meanings and rules below, then run the tool.
- Read result.observedElapsedLochiaDays. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyRecordedLochiaStartDate | Independently recorded lochia start date | string | Required |
| independentlyRecordedLochiaEndDate | Independently recorded lochia end date | string | Required |
Parse real Gregorian YYYY-MM-DD dates in years 0001–9999, including leap-year rules. Require endpoint no earlier than start and subtract calendar day ordinals. Equal dates return zero; no extra inclusive endpoint day or clock time is included.
elapsedCalendarDays=ordinal(endDate)−ordinal(startDate), endDate≥startDate Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.observedElapsedLochiaDays | Observed Elapsed Lochia Days | number |
{
"input": {
"independentlyRecordedLochiaStartDate": "2026-01-01",
"independentlyRecordedLochiaEndDate": "2026-01-15"
},

} Limitations and assumptions
Dating evidence, acquisition conditions and applicable clinical references remain independently established. The output describes supplied observations or a conditional model without diagnosing an outcome, choosing a dose or verifying clinical applicability.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
