Jury duty length varies depending on the jurisdiction and the type of trial:
- In Colorado, under the "one day/one trial" system, you serve either one day or for the length of the trial if selected. This means if you are not chosen, your service may end after one day; if selected, you serve for the entire trial duration
- In federal courts in Colorado, jurors are typically on-call for a one-month term, during which they may be summoned to serve. If selected for a trial, you serve until the case is complete, which can vary in length. After serving, you are excused for the remainder of that term
- Typical jury trials often last from 1 to 7 days. Most criminal trials can be 1–3 days, but some cases may extend longer, even weeks or months in complex or high-profile cases. Civil trials usually are shorter but can also vary
- A usual jury day runs from about 8:30 or 9:00 a.m. to 5:00 p.m., with breaks and lunch, though times may vary during deliberations or extended testimony
- Grand juries have different terms; for example, some serve one day a week for several months
In summary, jury duty can last from a single day (if not selected) to several days or weeks depending on the trial, with some jurisdictions requiring availability for up to a month on-call. The court typically informs jurors of expected trial length when selected. After serving, jurors often receive a period of exemption from future service (e.g., one year or more)
