N.Y. General Construction Law § 30: Month, computation

§ 30. Month, computation. A number of months after or before a certain

day shall be computed by counting such number of calendar months from

such day, exclusive of the calendar month in which such day occurs, and

shall include the day of the month in the last month so counted having

the same numerical order in days of the month as the day from which the

computation is made, unless there be not so many days in the last month

so counted, in which case the period computed shall expire with the last

day of the month so counted.
