Federal Rules of Criminal Procedure - Rule 45. Computing and Extending Time
(a) Computing Time.
The following rules apply in computing any time period specified in these rules, in any local rule or 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 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 45(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 45(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, local rule, 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, Independence Day, Labor Day, Columbus Day, Veterans’ Day, Thanksgiving Day, or Christmas Day;
(B) any day declared a holiday by the President or Congress; and
(C) for periods that are measured after an event, any other day declared a holiday by the state where the district court is located.
(1) In General.
When an act must or may be done within a specified period, the court on its own may extend the time, or for good cause may do so on a party’s motion made:
(A) before the originally prescribed or previously extended time expires; or
(B) after the time expires if the party failed to act because of excusable neglect.
The court may not extend the time to take any action under Rule 35, except as stated in that rule.
(c) Additional Time After Certain Kinds of Service.
Whenever a party must or may act within a specified period after service and service is made in the manner provided under Federal Rule of Civil Procedure 5(b)(2)(C), (D), (E), or (F), 3 days are added after the period would otherwise expire under subdivision (a).
