co-deadlines

Colorado Case Deadlines

NOT LEGAL ADVICE. This skill computes deadlines. Always independently verify in the cited rule or statute and confirm with the assigned judge's practice standards before treating any computed date as final.

Use this skill to compute deadlines under C.R.C.P. 6(a) (time computation), the Colorado legal-holiday list (C.R.S. § 24-11-101), and the various named rules across the C.R.C.P., C.R.S., and applicable federal law.

C.R.C.P. 6(a) — time computation

C.R.C.P. 6(a) governs how to count time intervals stated in Colorado statutes and rules:

1. Exclude the day of the triggering event (the event that starts the period running, e.g., service date)
2. Include every intermediate calendar day (no court-day skip for periods of 7+ days as of the 2012 rewrite)
3. Include the last day, unless it falls on a Saturday, Sunday, or Colorado legal holiday — in which case the period extends to the next day that is not one of those (C.R.C.P. 6(a)(1)(C))

For periods of fewer than 7 days that pre-date the 2012 rewrite, older case law applied court-day counting; modern C.R.C.P. 6 uses calendar-day counting throughout, with the roll-forward rule at the end. Some statutes outside the C.R.C.P. retain court-day counting explicitly (e.g., certain post-judgment garnishment intervals); read the controlling rule.

Colorado legal holidays — C.R.S. § 24-11-101

The following are Colorado state legal holidays:

Holiday	Date
New Year's Day	January 1
Martin Luther King, Jr. Day	3rd Monday in January
Presidents' Day (Washington's Birthday)	3rd Monday in February
Memorial Day	Last Monday in May
Juneteenth	June 19 (added 2022 by SB22-228)
Independence Day	July 4
Labor Day	1st Monday in September
Frances Xavier Cabrini Day	1st Monday in October (replaced Columbus Day per H.B. 20-1031, effective 2020)
Veterans Day	November 11
Thanksgiving Day	4th Thursday in November
Christmas Day	December 25

Saturday holiday observance: shifts to the preceding Friday (C.R.S. § 24-11-101(2)). Sunday holiday observance: shifts to the following Monday.

⚠ Note: Colorado does NOT observe the day after Thanksgiving as a state legal holiday (contrast Washington, which does, under RCW 1.16.050). Some judicial districts close administratively on the day after Thanksgiving but the C.R.S. § 24-11-101 list controls C.R.C.P. 6(a) arithmetic.

⚠ Cesar Chavez Day (March 31) is recognized in Colorado as a day of observance but is not a state legal holiday — it does not affect deadline counting.

Statute of limitations — primary Colorado claims

Colorado SOL provisions are scattered across Title 13. The key buckets:

Claim type	SOL	Authority	Notes
Liquidated debt / written instrument	6 years	C.R.S. § 13-80-103.5(1)(a)	Most consumer-credit-card claims; the "discovery rule" can apply
Promissory note	6 years	C.R.S. § 13-80-103.5(1)(a)
Open account (oral / implied)	6 years	C.R.S. § 13-80-103.5(1)(a)	Some debt-buyer cases argue 3 years under § 13-80-101; the post-2003 amendment moved most accounts to 6
General tort	2 years	C.R.S. § 13-80-102	Includes negligence, fraud (start at discovery)
Personal-injury motor vehicle	3 years	C.R.S. § 13-80-101(1)(n)
Libel / slander	1 year	C.R.S. § 13-80-103(1)(a)
CCPA	3 years from accrual	C.R.S. § 6-1-115
CFDCPA	1 year from violation	C.R.S. § 5-16-113(4)
FDCPA	1 year from violation	15 U.S.C. § 1692k(d)	Federal — applies in Colorado courts as well
Adverse possession	18 years	C.R.S. § 38-41-101	Colorado real-property quirk
Eviction (FED)	2 years on the debt; no SOL on possession	C.R.S. § 38-12 / § 13-40
Foreign judgments	6 years	C.R.S. § 13-80-103.5(1)(b)
Wrongful death	2 years	C.R.S. § 13-80-102(1)(d)

Tolling and revival

• Tolling for minority / disability: C.R.S. § 13-81-103 tolls SOL during a minor's minority or during certain disabilities
• Tolling for fraudulent concealment: discovery rule applies in fraud claims (start counting at discovery, not accrual)
• Partial payment / written acknowledgment: a written acknowledgment of a debt or a partial payment restarts the SOL clock under C.R.S. § 13-80-113 — important in debt-buyer cases where the creditor may rely on a recent "promise to pay" to revive a stale claim. Hassler v. Account Brokers of Larimer Cnty., Inc., 2012 CO 24, addresses this; verify still good law.

How co-deadlines composes with the scripts

The skill body above is the reference. The actual arithmetic lives in scripts/case-calendar.py, which:

• Encodes the C.R.S. § 24-11-101 holidays
• Implements co_holidays(year) for any year
• Provides is_court_day(d), roll_forward_rule(d), add_calendar_days, add_court_days
• Exposes a RULES dictionary mapping named rule keys to (days, mode, description, authority)

Use scripts/case-calendar.py --rules for the canonical list and scripts/case-calendar.py --from YYYY-MM-DD --rule <key> for any specific computation.

Composition

• For format: co-statewide-format
• For the substantive rule: co-law-references
• For first-response timing: co-first-30-days
• For motion timing: co-discovery, co-schedule-hearing
• For post-judgment timing: co-post-judgment
• For family-law specific deadlines: co-family-law
