(a) Computation. In computing any period of time, prescribed or allowed by these rules, the day of the event from which the designated period of time begins to run is not to be included. Thereafter, every day shall be counted including holidays, Saturdays, and Sundays. The last day of the period so computed is to be included, unless it is a Saturday, a Sunday, or a legal holiday, in which event the period runs until the end of the next day which is not a Saturday, a Sunday, or a legal holiday. The "next day" is determined by continuing to count forward when the period is measured after an event and backward when measured before an event. As used in these Rules, "legal holiday" includes the first day of January, observed as New Year's Day; the third Monday in January, observed as Martin Luther King Day; the third Monday in February, observed as Washington-Lincoln Day; the last Monday in May, observed as Memorial Day; the fourth day of July, observed as Independence Day; the first Monday in September, observed as Labor Day; the second Monday in October, observed as Columbus Day; the 11th day of November, observed as Veteran's Day; the fourth Thursday in November, observed as Thanksgiving Day; the twenty-fifth day of December, observed as Christmas Day, and any other day except Saturday or Sunday when the court is closed. (b) Enlargement. When an act is required or allowed to be performed at or within a specified time, the court for cause shown may at any time in its discretion: (1) Upon motion, with or without notice, order the period enlarged if application therefor is made before expiration of the period originally prescribed or of that period as extended by a previous order; or (2) Upon motion permit the act to be done after expiration of the specified period if the failure to act on time was the result of excusable neglect. (d) For Motions -- Affidavits. A written motion, other than one which may be heard ex parte, and notice of the hearing thereon, shall be served not later than 7 days before the time specified for the hearing, unless a different period is fixed by rule or order of court. For cause shown, such an order may be made on ex parte application. 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 otherwise ordered by the court.
