Rule 128 - Computing and Extending Time; Time for Motion Papers
(a) COMPUTING TIME. The following rules apply in computing any time period specified in these rules, in any court order, or in any statute that does not specify a method of computing time.
(1)Period Stated in Days or a Longer Unit. 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 a legal holiday, the period continues to run until the end of the next day that is not a Saturday, Sunday, or legal holiday.
(2)Period Stated in Hours. When the period is stated in hours:
(A) begin counting immediately on the occurrence of the event that triggers the period;
(B) count every hour, including hours during intermediate Saturdays, Sundays, and legal holidays; and
(C) if the period would end on a Saturday, Sunday, or legal holiday, the period continues to run until the same time on the next day that is not a Saturday, Sunday, or legal holiday.
(3)Inaccessibility of the Clerk's Office. Unless the court orders otherwise, if the clerk's office is inaccessible:
(A) on the last day for filing under Rule 128(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 128(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)"Last Day" Defined. Unless a different time is set by a statute or court order, the last day ends:
(A) for electronic filing, at midnight in the court's time zone; and
(B) for filing by other means, when the clerk's office is scheduled to close.
(5) "Next Day" Defined. 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" Defined . "Legal holiday" means:
(A) the day set aside by statute for observing New Year's Day, Martin Luther King Jr.'s Birthday, Washington's Birthday, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans' Day, Thanksgiving Day, or Christmas Day; and
(B) any day declared a holiday by the President or Congress, or observed as a holiday by the court.
(b) EXTENDING TIME.
(1)In General. 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 the 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)Exceptions. A court must not extend the time to act under Rule 125 and Civil Rules 52(b), 59(b), (d), and (e), and 60(b).
(c) TIME FOR SERVING AFFIDAVITS. Any affidavit supporting a motion or opposition must be served with the motion or opposition unless the court orders otherwise.
(d) ADDITIONAL TIME AFTER CERTAIN KINDS OF SERVICE. When a party may or must act within a specified time after being served and service is made by mail or leaving with the clerk, 3 days are added after the period would otherwise expire under this Rule 128(a).
