I was called to JD a month or so ago for PETIT jury. The length of time you serve is dependent upon the jury type specified, at least in my state. The longest jury types are CAPITAL juries (murder, manslaughter, etc.) and GRAND juries (30-90 days usually). Most PETIT jury cases if not plead out or settled last 1-3 days. I was called up into a court room and actually called into the jury box but was promptly dismissed since the case was against a black police officer charged with offensive touching and assault, and I think the defense was looking to minimize white middle class guys as part of the jury. They went through almost the entire 40 person contingent sent up into the court room before the final 12 jurors were selected for the case. I then went back to the jury selection room and got my two year "get out of jail free" card for be willing to serve. I would actually liked to have served on the jury but it just wasn't my time I guess.

My wife has been summoned twice this fall but since we homeschool she got out of it, she's the only teacher.
