Limitations and assumptions

No relief notice, affected location, filing category or automatic holiday adjustment is checked. Verify real calendar dates because JavaScript can normalize overflowing days.

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.

Alternative or Complementary methods

Use Deadline Business-Day Shift: Move a nominal deadline forward past weekends and caller-supplied nonbusiness dates. For a complementary task, use CDP Appeal Window: Check a collection appeal filing date against a caller-supplied window.
