(a)(1) Computation. 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 Repealed.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 Repealed. (e) Additional Time After Service Under C.R.C.P. 5(b)(2)(B), (C), or (D). Repealed.

Plain-English Summary
Rule 6 is the counting rule behind every deadline the C.R.C.P. sets. Skip the day of the triggering event or order, then count every day after that, including weekends and holidays, until the deadline arrives. If that last day lands on a Saturday, Sunday, or legal holiday, the deadline slides to the next day that isn't one of those. A specific list of state and federal holidays qualifies for this purpose, along with any other day the court happens to be closed.
The rule also gives courts room to adjust deadlines. A court can enlarge a deadline for good cause before it expires, and after it expires if the missed deadline resulted from excusable neglect, except a court can never extend the time to attack a judgment under Rule 60(b), and can extend a Rule 59 deadline only to the extent Rule 59 itself allows. An older provision that once added extra days to a deadline when the underlying paper was served by mail or another indirect method has been repealed, so those methods no longer buy extra time.
Frequently Asked Questions
How do I count the days for a filing deadline in Colorado?
Skip the day of the event that starts the clock, then count every following day, including weekends and holidays, until the deadline; if the final day falls on a weekend or legal holiday, it moves to the next day that isn't.
Can a Colorado court extend a deadline that already passed?
Do I get extra days to respond if I was served by mail?
No. Colorado repealed the provision that once added extra time after service by mail or other indirect methods, so those deadlines run on the same schedule as any other.
What counts as a legal holiday for computing a Colorado court deadline?
A specific list set out in Rule 6, including New Year's Day, Memorial Day, Juneteenth, Independence Day, Thanksgiving, and Christmas among others, plus any other day the court is closed.
