Rule 14 - Computation and Extension of Time(a) Computation of Time. In computing any period of time prescribed by these rules, by order of court, or by any applicable statute, the day of the act, event, or default after which the designated period of time begins to run shall not be included. The last day of the period shall be included, unless it is a Saturday, Sunday, or legal holiday, in which event the period shall extend until the end of the next day which is not a Saturday, Sunday, or legal holiday. When the period of time prescribed or allowed is less than 7 days, intermediate Saturdays, Sundays, and legal holidays shall be excluded in the computation. As used in this rule "legal holiday" means those days specified in G.L. c. 4, § 7 and any other day appointed as a holiday by the President or the Congress of the United States or so designated by the laws of the Commonwealth.(b) Enlargement of Time. The appellate court or a single justice of the appellate court in which the appeal will be, or is, docketed for good cause shown may upon motion enlarge the time prescribed by these rules or by its order for doing any act, or may permit an act to be done after the expiration of such time; but neither the appellate court nor a single justice may enlarge the time for filing a notice of appeal beyond 1 year from the date of entry of the judgment or order sought to be reviewed, or, in a criminal case, from the date of the verdict or finding of guilt or the date of imposition of sentence, whichever date is later.(c) Additional Time After Service by First Class Mail or Its Equivalent. Whenever a party is required or permitted to do an act within a prescribed period after service of a document upon the party and the document is served by first class mail or its equivalent, 3 days shall be added to the prescribed period.Amended May 15, 1979, effective 7/1/1979; amended October 31, 2018, effective 3/1/2019.
