Rule 1.25 - COMPUTATION OF TIME
(1) In computing any period of time prescribed or allowed by these rules or order of the court, the day of the act, event, or default 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 that day is a Saturday, a legal holiday (including Sunday), or a day or part of a day on which the court is closed for the purpose of filing documents, closed to the extent ordered by the Chief Justice, or closed before the end of normal working hours during which documents may be filed. In any of those events, the period runs until the end of the next day the court is open.
(2) When the period of time prescribed or allowed relates to serving a public officer or filing a document at a public office, and if the last day falls on a day when that particular office is closed before the end of or for all of the normal work day, the last day shall be excluded in computing the period of time within which service is to be made or the document is to be filed, in which event the period runs until the close of office hours on the next day the office is open for business.
(3) When a party intends to file by mail a brief or other thing, other than a notice of appeal or other document subject to ORS 19.260, and the brief or other thing is due on a date that all local United States Postal Service facilities unexpectedly are closed in whole or in part, the party filing the brief or other thing shall have until the next day that United States Postal Service facilities are open to file the brief or other thing.
