Rule 1.10. Computation of Time
(a) General Time Computation. When computing any time period more than 24 hours prescribed by these rules, by court order, or by an applicable statute, the following rules apply:
(1) Day of the Event. Exclude the day of the act or event from which the designated time period begins to run.
(2) Last Day. Include the last day of the period, unless it is a Saturday, Sunday or legal holiday, in which case the period ends on the next day that is not a Saturday, Sunday, or legal holiday.
(3) Time Period Less Than 7 Days. If the time period is less than 7 days, exclude intermediate Saturdays, Sundays and legal holidays from the computation.
(4) Next Day. The “next day” is determined by counting forward when the period is measured after an event, and backward when measured before an event.
(5) Additional Time After Service. If a party may or must act within a specified time after service and service is made under a method authorized by Rule 1.7(c)(2)(C), (D), or (E), 5 calendar days are added after the specified time period would otherwise expire under (a)(1)-(4), except as provided in Rule 31.3(d). This provision does not apply to the clerk's distribution of notices, minute entries, or other court-generated documents.
(b) If an Arraignment is not Held. If an arraignment is not held under Rule 14.5, the date of arraignment for the purpose of computing time is the date the defendant receives notice of the next court date under Rule 5.8.
(c) Entry. A court order is entered when the clerk files it.
(v) Victims' Rights. The time computation provisions of (a) also apply to victims.
