(a) Computation.(1) In computing any period of time prescribed or allowed by these rules, by order of court, or by an applicable statute, 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 fourth day of July, observed as Independence Day; the first Monday in September, observed as Labor Day; the second Monday in October, observed as Columbus Day; the eleventh 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 Rules 325 and 360(b), except to the extent and under the conditions stated in them. (c) Unaffected by Expiration of Term. Repealed. (d) Notice, Motion, Affidavits. Repealed. (e) Additional Time on Service Under C.R.C.P. 305(b)(2)(B), (C), or (D). Repealed. (e) amended July 22, 1993, effective 1/1/1994; (a) amended and effective 8/4/1994; (a) and (e) amended and effective and (e) committee comment added and effective 6/28/2007; (a) amended and (c), (d), and (e) and (e) committee comment repealed and adopted December 14, 2011, effective 1/1/2012, for all cases pending on or filed on or after 1/1/2012, pursuant to C.R.C.P. 1(b); comment added and adopted June 21, 2012, effective 7/1/2012.COMMENT
After the particular effective date, time computation in most situations is intended to incorporate the Rule of Seven. Under the Rule of Seven, a day is a day, and because calendars are divided into 7-day week intervals, groupings of days are in 7-day or multiples of 7-day intervals. Groupings of less than 7 days have been left as they were because such small numbers do not interfere with the underlying concept. Details of the Rule of Seven reform are set forth in an article by Richard P. Holme, 41 Colo. Lawyer, Vol. 1, P 33 (January 2012).
Time computation is sometimes "forward," meaning starting the count at a particular stated event [such as date of filing] and counting forward to the deadline date. Counting "backward" means counting backward from the event to reach the deadline date [such as a stated number of days being allowed before the commencement of trial]. In determining the effective date of the Rule of Seven time computation/time interval amendments having a statutory basis, said amendments take effect on July 1, 2012 and regardless of whether time intervals are counted forward or backward, both the time computation start date and deadline date must be after June 30, 2012. Further, the time computation/time interval amendments do not apply to modify the settings of any dates or time intervals set by an order of a court entered before July 1, 2012.
