Token Rotation Due

Calculate API token rotation due date and overdue status.

Description

Token rotation schedules use an explicitly chosen interval and assessment date.

Token rotation schedules use an explicitly chosen interval and assessment date. Due-date arithmetic does not rotate credentials.^[1]

Calculate API token rotation due date and overdue status.

When to use Token Rotation Due

Use this tool to calculate API token rotation due date and overdue status.

Prepare the documented facts, aligned totals or expected/observed evidence labels requested. Choose applicable requirements and thresholds separately before interpreting a planning screen.

How to use Token Rotation Due and understand its results

Prepare the documented facts, aligned totals or expected/observed evidence labels requested. Choose applicable requirements and thresholds separately before interpreting a planning screen.
Enter lastRotationDate, rotationIntervalDays, asOfDate using the field table and calculation rules, then run the tool.
Read nextRotationDate, daysUntilRotation, rotationOverdue. 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
lastRotationDate	Last token rotation date	string	Required
rotationIntervalDays	Rotation interval (days)	integer; minimum: 1	Required
asOfDate	As-of date	string	Required

Enter parseable date-only strings interpreted at UTC midnight and positive integer interval. Return next date, signed days remaining and overdue only when negative.

next=last+interval; daysUntil=ceil((next−asOf)/day)

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

Output field	Meaning	Value type
nextRotationDate	Next rotation date	string
daysUntilRotation	Days until rotation	integer
rotationOverdue	Rotation is overdue	boolean

{
  "input": {
    "lastRotationDate": "2025-01-01",
    "rotationIntervalDays": 90,
    "asOfDate": "2025-03-01"
  },
  "output": {
    "nextRotationDate": "2025-04-01",
    "daysUntilRotation": 31,
    "rotationOverdue": false
  }
}

Limitations and assumptions

As-of may precede last rotation. Native parsing may normalize dates; no secrets, actual rotation or security policy is verified.

Numeric inputs, where present, 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.
