(a) Computation.

In computing any period of time prescribed or allowed by these rules, by the local rules of any superior court, by order of court, or by 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 so computed shall 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 neither a Saturday, a Sunday nor a legal holiday. Legal holidays are prescribed in RCW 1.16.050. 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.

(b) Enlargement.

When by these rules or by a notice given thereunder or by order of court 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 therefore 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 where the failure to act was the result of excusable neglect; but it may not extend the time for taking any action under rules 50(b), 52(b), 59(b), 59(d), and 60(b).

(c) Proceeding Not To Fail for Want of Judge or Session of Court.

No proceeding in a court of justice in any action, suit, or proceeding pending therein, is affected by a vacancy in the office of any or all of the judges or by the failure of a session of the court.

(d) For Motions--Affidavits.

A written motion, other than one which may be heard ex parte, and notice of the hearing thereof shall be served not later than 5 days before the time specified for the hearing, unless a different period is fixed by these rules or by order of the court. Such an order may for cause shown be made on ex parte application. When a motion is supported by affidavit, the affidavit shall be served with the motion; and, except as otherwise provided in rule 59 (c), opposing affidavits may be served not later than 1 day before the hearing, unless the court permits them to be served at some other time.

(e) Additional Time After Service by Mail.

Whenever a party has the right or is required to do some act or take some proceedings within a prescribed period after the service of a notice or other paper upon the party and the notice or paper is served upon the party by mail, 3 days shall be added to the prescribed period.
