Rule 26 - Computation and Extension of Time(a) Computation of time. In computing any period of time prescribed by these rules, an order of court, or any applicable statute, the day of the act, event, or default from 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 a legal holiday, in which event the period extends until the end of the next day that is not a Saturday, a Sunday, or a legal holiday. When the period of time prescribed or allowed is less than 7 days, any intervening Saturday, Sunday, or legal holiday shall be excluded in the computation.(b)Extension of time. The Hawai'i appellate courts, or any judge or justice thereof, for good cause shown upon motion may extend the time prescribed by these rules for doing any act, or may permit an act to be done after the expiration of such time. Provided however, no court or judge or justice is authorized to change the jurisdictional requirements contained in Rule 4 of these rules.(c)Additional time after service by mail. Whenever a party is required or permitted to do an act within a prescribed time after service of a document, and the document is served by mail, 2 extra days shall be added to the prescribed period.(d)Shortening time. A judge or justice for good cause shown may shorten the time for serving or filing a notice of motion or other document incident to an appeal or an original proceeding in the reviewing court. A motion to shorten time shall be made as provided in Rule 27.(e) Relief from default. The reviewing court for good cause shown may relieve a party from a default occasioned by any failure to comply with these rules, except the failure to give timely notice of appeal.Amended December 6, 1999, effective 1/1/2000; further amended August 30, 2010, effective 9/27/2010.
