(a) Computing time. The following rules apply in computing any time period specified in these rules, any local rule or court order, or in any statute that does not specify a method of computing time.
(1) When the period is stated in days or a longer unit of time:
(A) exclude the day of the event that triggers the period;
(B) count every day, including intermediate Saturdays, Sundays, and legal holidays; and
(C) include the last day of the period, but if the last day is a Saturday, Sunday, or legal holiday, the period continues to run until the end of the next day that is not a Saturday, Sunday, or legal holiday.
(2) When the period is stated in hours:
(A) begin counting immediately on the occurrence of the event that triggers the period; and
(B) count every hour, including hours during intermediate Saturdays, Sundays, and legal holidays.
(3) Unless the court orders otherwise, if the clerk’s office is inaccessible:
(A) on the last day for filing under Rule 6(a)(1), then the time for filing is extended to the first accessible day that is not a Saturday, Sunday or legal holiday; or
(B) during the last hour for filing under Rule 6(a)(2), then the time for filing is extended to the same time on the first accessible day that is not a Saturday, Sunday, or legal holiday.
(4) Unless a different time is set by a statute or court order, filing on the last day means:
(A) for electronic filing, at midnight; and
(B) for filing by other means, the filing must be made before the clerk’s office is scheduled to close.
(5) 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.
(6) “Legal holiday” is any holiday that is recognized and observed by the State of Utah, as specified here: https://www.utcourts.gov/en/about/miscellaneous/law-library/holidays.html
(b) Extending time.
(1) When an act may or must be done within a specified time, the court may, for good cause, extend the time:
(A) with or without motion or notice if the court acts, or if a request is made, before the original time or its extension expires; or
(B) on motion made after the time has expired if the party failed to act because of excusable neglect.
(2) A court must 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) Additional time after service by mail. When a party may or must act within a specified time after service and service is made by mail, three days are added after the period would otherwise expire under paragraph (a).
