Description
Parse real YYYY-MM-DD dates.
Extension-service time budgets distinguish contact, travel, closed cases, credited pauses and source-validity periods. Allocated person-time differs from elapsed time, while half-open source periods differ from closed deadline checks. A supplied deadline or pause is not automatically an official service requirement.
Parse real YYYY-MM-DD dates.
When to use this tool
Use Advisory Source Period Gap when checking the stated contact/travel, response or source-period convention.
How to use the tool and how it works
- Enter adviceDate, sourceStartDate, sourceEndDate, reviewDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read daysFromSourceStart, daysToSourceEnd, ageAtReviewDays, insideSourcePeriod. Inspect insideSourcePeriod before interpreting the associated values.
Parse real YYYY-MM-DD dates. Require source end>=start and review>=advice. Return signed advice-minus-start/source-end-minus-advice day gaps, review age and membership in the half-open source interval [start,end).1

}Limitations and assumptions
- Dates use UTC day arithmetic without business calendars; no actual publication validity or current agronomic advice 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.
Alternative or Complementary methods
Use verified clock, journey and source records with the governing service and reimbursement policies for actual performance or payment decisions.
