W.R.Cr.P. 45
Rule 45. Time
(a) Computation. — In computing any period of time, the day of the act or
event from which the designated period of time begins to run shall not be
included. The last day of the period so computed shall be included, unless it is
a Saturday, a Sunday, or a legal holiday, or, when the act to be done is the filing
of a paper in court, a day on which weather or other conditions have made the
office of the clerk of the court inaccessible, in which event the period runs until
the end of the next day which is not one of the aforementioned days. Except for
the time periods prescribed in Rules 5, 6, 12.1, 12.2, 12.3, 21, 32 and 46.1, when
a period of time prescribed or allowed is less than 11 days, intermediate
Saturdays, Sundays and legal holidays shall be excluded in the computation.
As used in these rules, “legal holiday” includes New Year’s Day, Martin Luther
King, Jr./Wyoming Equality Day, Washington’s Birthday, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day, Christmas Day,
and any day officially recognized as a legal holiday in this state by designation
of the legislature or appointment as a holiday by the governor.
(b) Enlargement. — When an act is required or allowed to be done at or
within a specified time, the court, for cause shown, may at any time in its
discretion:
(1) With or without motion or notice, order the period enlarged if request
therefor is made before the expiration of the period originally prescribed or
as extended by a previous order; or
(2) Upon motion made after the expiration of the specified period, permit
the act to be done if the failure to act was the result of excusable neglect, but
the court may not extend the time for taking any action under Rules 29, 33,
34 and 35 except to the extent and under the conditions stated in them.
(c) Motions and affidavits. — A written motion, other than one which may be
heard ex parte, and notice of the hearing thereof, shall be served not later than
five days before the time specified for the hearing unless a different period is
fixed by rule or order of the court. For cause shown such an order may be made
on ex parte application. When a motion is supported by affidavit, the affidavit
shall be served with the motion; and opposing affidavits may be served not less
than one day before the hearing unless the court permits them to be served at
a later time.
(d) Additional time after service by mail. — Whenever a party has a right or
is required to do an act within a prescribed period after the service of a notice
or other paper upon that party and the notice or other paper is served upon
that party by mail, three days shall be added to the prescribed period.
(e) Continued existence or expiration of term of court. — The period of time
provided for the doing of any act or the taking of any proceeding is not affected
or limited by the continued existence or expiration of a term of court. The
continued existence or expiration of a term of court in no way affects the power
of a court to do any act or take any proceeding in any criminal action which has
been pending before it.
