Check the result before use

This is a self-check calculation of the sourced base period, not a final filing instruction. Colorado legal holidays, court-specific closures and emergency closure orders are not bundled. Weekend expiries are identified but not shifted, and a weekday result may still be a local non-business day. Check C.R.C.P. 6(a) and C.A.R. 26(a) and the current court calendar before filing or serving. Check the cited rule, the correct factual branch, every order and any electronic-filing cut-off.

C.R.C.P. 12(a)(1)AdvisoryVerify against the rules

Service outside Colorado, service by publication or a special order generally uses the separate 35-day branch. A timely Rule 12 motion changes the responsive-pleading deadline.

Legal disclaimer

Deadline Engine calculates dates from encoded procedural rules. It is software, not legal advice, and no output is approved for your matter. Check the jurisdiction, inputs, current cited rule, facts and any order or agreement before recording or using the date. Responsibility for the operative deadline and diary remains with you.
