How to use Demand Response Window and understand its results

Prepare the supplied policy terms, dates, assumptions or recorded indicators requested. Keep monetary amounts on one currency basis and select the applicable thresholds separately.
Enter demandReceivedDate, acknowledgmentDays, acknowledgedDate using the field table and calculation rules, then run the tool.
Read acknowledgmentDeadline, responseDays, daysLate, onTime. The explanation below defines the units, signs, ordering and any flags or placeholder values.
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
demandReceivedDate	Demand received date	string	Required
acknowledgmentDays	Acknowledgment window (days)	integer; minimum: 0	Required
acknowledgedDate	Acknowledged date	string	Required

Enter parseable UTC dates in chronological order and nonnegative integer acknowledgment days. Return deadline, response days, clipped late days and onTime when late days are zero. Equality passes.

deadline=received plus days; responseDays=floor((acknowledged−received)/day)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
acknowledgmentDeadline	Acknowledgment deadline	string
responseDays	Response days	integer; minimum: 0

Limitations and assumptions

Native dates can normalize. No business-day calendar, jurisdictional legal deadline, demand service or actual acknowledgment is verified.

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.
