Choose the specific arithmetic or checklist scenario and establish its input amounts, dates, rates and criteria from the applicable records. Keep currencies, periods and jurisdictions consistent; review the tool-specific assumptions before interpreting the result.

If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
serviceDate	Summons service date	string	Required
responseDays	Response window (days)	integer; minimum: 0	Required

Enter service/as-of dates as YYYY-MM-DD and a nonnegative integer response period. Parse midnight UTC, add calendar days to service and return deadline, signed days remaining and overdue only for a negative remainder.

deadline=noticeDate+responseDays; daysRemaining=ceil((deadline−asOf)/86400000)

Limitations and assumptions

No weekend, holiday, service-date or legal extension rule is applied. Some impossible calendar days can normalize in JavaScript Date; verify actual dates externally.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
