Colo. R. Civ. P. 6 (2026)

(a) Computation. (1) In computing any period of time prescribed or allowed by these rules, the day of the act, event, or default from which the designated period of time begins to run shall not be included. Thereafter, every day shall be counted, including holidays, Saturdays or Sundays. The last day of the period so computed shall be included, unless it is a Saturday, a Sunday, or a legal holiday, in which event the period runs until the end of the next day which is not a Saturday, a Sunday, or a legal holiday. 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.

(2) As used in this Rule, ‘‘Legal holiday’’ includes the first day of January, observed as New Year’s Day; the third Monday in January, observed as Martin Luther King Day; the third Monday in February, observed as Washington-Lincoln Day; the last Monday in May, observed as Memorial Day; the nineteenth day of June, observed as Juneteenth Day; the fourth day of July, observed as Independence Day; the first Monday in September, observed as Labor Day; the first Monday in October, observed as Frances Cabrini Day; the 11th day of November, observed as Veteran’s Day; the fourth Thursday in November, observed as Thanksgiving Day; the twenty-fifth day of December, observed as Christmas Day, and any other day except Saturday or Sunday when the court is closed.

(b) Enlargement. When by these rules or by a notice given thereunder or by order of court 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 where the failure to act was the result of excusable neglect; but it may not extend the time for taking any action under Rule 60(b) and may extend the time for taking any action under Rule 59 only as allowed by that rule.

(c) Unaffected by Expiration of Term. Repealed.

(d) For Motions — Affidavits. Repealed.
