Which event controls this CPLR 214-a, ordinary branch inquiry?

Use the ordinary section 214-a branch after independently establishing the act, omission or qualifying last-treatment event. This calculator accepts events after November 3, 2020 and does not apply any toll.

Continuous treatment must concern the same illness, injury or condition giving rise to the complained-of conduct. The mere existence of later appointments does not establish this event.

The statute excludes patient-requested examinations solely to ascertain the state of the patient’s condition from continuous treatment.

Foreign objects and alleged failure to diagnose cancer or a malignant tumor have separate statutory branches. Public-defendant prerequisites require separate review.

How is this selected component counted?

  1. Use the ordinary section 214-a branch after independently establishing the act, omission or qualifying last-treatment event. This calculator accepts events after November 3, 2020 and does not apply any toll.
  2. Count the selected calendar-month or calendar-year interval from the independently established event. General Construction Law 20 excludes the event day, sections 30 and 58 govern months and years, and section 25-a permits the next succeeding business day when an authorized statutory act ends on Saturday, Sunday or a public holiday.
  3. Check the final statutory holiday and weekend independently.
  4. Preserve the actual commencement record and complete required service. Filing and service are separate acts.

For an authorized statutory act, General Construction Law 25-a permits the next succeeding business day if the final day is Saturday, Sunday or a statutory public holiday. Section 24 defines those holidays. Sunday Independence Day in 2027 is observed on Monday July 5. Confirm other actual closures separately.

The calculators accept selected events after November 3, 2020. They do not apply the 2020 executive-order toll. Brash distinguishes a toll from a suspension. Historical events require separate review and receive no calculated or paid date here. Do not add 228 days to every historical event without testing its actual applicability.
