Under NY Insurance Law § 3203, what is the minimum grace period required for a life insurance policy?

Why this is the answer

§ 3203(a)(1) requires that every life policy issued in NY include a grace period of 'one month, but not less than thirty-one days' during which a missed premium may be paid without forfeiture of coverage. If the insured dies during the grace period, the death benefit is paid net of the unpaid premium. 10 and 15 days are common free-look or other-state grace numbers; 60 days exceeds the NY mandate.
