Rule 2. Time.
(a) In computing any period of time, the day of the act or event from which the designated period of time begins to run shall not be included. The last day of the period so computed shall be included, unless it is a Saturday, a Sunday, or a legal holiday. When a period of time prescribed or allowed is less than 11 days, intermediate Saturdays, Sundays, and legal holidays shall not be included in the computation.
(b) When an act is required or allowed to be done at or within a specified time, the court for cause shown may, at any time in its discretion:
(1) with or without motion or notice, order the period enlarged if request therefor is made before the expiration of the period originally prescribed or as extended by a previous order; or
(2) upon motion made after the expiration of the specified period, permit the act to be done if there was a reasonable excuse for the failure to act; but the court may not extend the time for taking any action under the rules applying to a judgment of acquittal, new trial, arrest of judgment and appeal, unless otherwise provided in these rules.
(c) A written motion other than one that may be heard ex parte and notice of the hearing thereof shall be served not later than five days before the time specified for the hearing, unless a different period is fixed by rule or order of the court. When a motion is supported by affidavit, the affidavit shall be served with the motion and opposing affidavits may be served not less than one day before the hearing unless the court permits them to be served at a later time.
