Colorado Civil Procedure Deadline Calculator
Computed under C.R.C.P. 6(a) and the “Rule of 7” · 49 deadlines across 8 categories
Pick a deadline, enter the trigger date, and this tool applies Colorado's own time-computation rule — excluding the trigger day, counting every calendar day, and rolling the terminal day off weekends and Colorado's own legal holidays — and shows its work, step by step, with the governing rule or statute cited. Colorado's current rules have no mail or e-service extension (Rule 6(e) is repealed) and no general motion-notice default in Rule 6 itself (Rule 6(d) is repealed, delegated to C.R.C.P. 121 § 1-15) — two points this tool builds in directly rather than assuming by analogy to other states.
Advanced: additional non-court days
This tool always applies Colorado's own current legal-holiday list under C.R.C.P. 6(a)(2) (New Year's, MLK Day, Washington-Lincoln Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Frances Cabrini Day, Veterans Day, Thanksgiving, and Christmas — the same list applies to every deadline regardless of direction, unlike the federal rule), with a fixed-date holiday landing on a weekend shifted to the nearest weekday as an applied convention, since Rule 6(a)(2) itself has no separately codified shift rule — only a catch-all for "any other day... when the court is closed." Add any other closure the district court actually observes as a comma-separated YYYY-MM-DD date.
What this tool does not compute
- County court civil procedure. Claims up to $25,000 follow the separate, simplified C.R.C.P. 501–521 rule set, outside Rules 1–121.
- Domestic relations, juvenile, mental health, probate, and water court proceedings, and C.R.C.P. 106 (review of governmental/quasi- judicial action, its own strict 28-day jurisdictional window) and C.R.C.P. 120 (deed-of-trust sale authorization) — all expressly excluded from the ordinary Rules 16/26 case-management timeline and run on their own schedules.
- Eviction (forcible entry and detainer). Governed by C.R.S. Title 13, Article 40, a genuinely faster statutory track largely outside the C.R.C.P. — a possible future dedicated tool, not folded in here.
- Removal to federal court. 28 U.S.C. § 1446 is federal law, identical regardless of which state a case started in — use this site's own Federal Deadline Calculator instead of a duplicate entry here.
