Rule 4. Time.
(a) In computing time under these rules, 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 legal holiday, in which event the period runs until the end of the next day which is not a Saturday, Sunday or legal holiday. When a period of time allowed is less than 11 days, without reference to any additional time under subsection (d), intermediate Saturdays, Sundays and legal holidays shall be excluded from the computation.
(b) The court may, with or without motion or notice, for cause shown, order the time period enlarged if request is made before the period has expired. The court may consider a motion to grant an enlargement of a time period made after the period has expired, and may grant the motion, if there is a reasonable excuse for failure to act within the period.
(c) A written motion, other than one which may be heard ex parte, and notice of the hearing shall be served not later than five days before the time specified for the hearing, unless a different period is fixed by these rules or by court order. An order fixing the period of time may for cause shown be made on an ex parte application. When the motion is supported by an affidavit, the affidavit shall be served with the motion, and opposing affidavits may be served not later than one day before the hearing unless otherwise ordered by the court.
(d) Whenever a party has the right or is required to do some act or take some proceedings within a prescribed time period after the service of a notice or other paper upon the party and the notice or paper is served by mail, three days shall be added to the prescribed period as calculated under subsection (a). Saturdays, Sundays, and legal holidays shall be included in the computation of any three-day period under this subsection, except that if the last day of the three-day period is a Saturday, Sunday, or a legal holiday, the period shall run until the end of the next day which is not a Saturday, Sunday, or a legal holiday.
