How to use Researcher Registration Expiry Days Remaining Calculator and understand its results

Prepare the inventory, measurements or policy dates for the collection and reporting period. Confirm units, record order and any independently established thresholds or permissions.
Enter registrationIssueOrdinals, callerRegistrationValidDays, asOfDayOrdinal using the field table and calculation rules, then run the tool.
Read registrationExpiryOrdinals, signedRegistrationDaysRemaining, expiredBeforeAsOfFlags. 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
registrationIssueOrdinals	Registration issue ordinals	list of number	Required
callerRegistrationValidDays	Caller registration valid days	list of number	Required
asOfDayOrdinal	As of day ordinal	integer	Required

Pair nonnegative integer issue ordinals and validity periods in days with a nonnegative as-of ordinal. Future issue dates are rejected. Return expiry ordinals, signed days remaining and binary flags for expiry strictly before as-of. A registration with expiry equal to as-of remains unexpired under this convention.

Paired lists must be nonempty and have equal lengths.

expiry = issue + validDays; remaining = expiry−asOf; expired = expiry<asOf

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

Output field	Meaning	Value type
registrationExpiryOrdinals	Registration expiry ordinals	list of number
signedRegistrationDaysRemaining	Signed registration days remaining	list of number
expiredBeforeAsOfFlags	Expired before as of flags	list of number

Limitations and assumptions

The lifetime and inclusive-day rule are supplied policy. This calculation does not authenticate researchers, grant access or evaluate eligibility.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Vital Record Review Cycle Interval Scheduler: Schedule vital-record review with explicit advance-alert window and overdue exposure; unlike inspection cadence, imminent reviews are separately flagged, not a statutory review rule. For a complementary task, use Deed of Gift Restriction Expiry Countdown Calculator: Reconcile deed restriction countdown with independently documented release state and flag mismatches; no deed interpretation or automatic access/copyright permission.
