Rule 6. Time.

A. COMPUTATION. When the computation of any period of time prescribed or allowed by these rules is by order of a court or by any applicable statute, the day of the act, event, or default after which the designated period of time begins to run may not be included. The last day of the period so computed must be included unless it is a Saturday, Sunday, or legal holiday, in which event the period runs until the end of the next day that is not a Saturday, Sunday, or legal holiday.

B. EXTENSION. When by these rules, by a notice given under these rules, or by order of a court an act is required or allowed to be done at or within a specified time, the judge for cause shown may extend the period if a motion is made before the expiration of the period originally prescribed or extended by previous permission of the court or after expiration of the specified period if failure to act was the result of excusable neglect.

C. ADDITIONAL TIME AFTER SERVICE BY MAIL. Whenever a party has the right or is required to do an act or take a proceeding within a prescribed period after service of a notice or other paper and the notice or other paper is served by mail, 3 days must be added to the prescribed period.
