How Long Your First Day of Jury Duty Usually Takes
Your first day of jury duty typically runs from 8 or 9 a.m. until 4 or 5 p.m., though the exact hours depend on your court. You will spend most of that time in a waiting area called the jury assembly room, not in a courtroom. The court calls groups of potential jurors — called a venire — and sends them to specific courtrooms for jury selection, which is called voir dire.
If your group is not called that day, you will be dismissed and told to return the next morning. If you are called to a courtroom, jury selection itself can take anywhere from one hour to most of the day, depending on the case type and how many lawyers want to question you. Criminal cases and civil lawsuits with high stakes tend to have longer jury selection than small claims or traffic cases.
Once a jury is seated and the trial begins, the length of your service depends entirely on the case. Some trials last one day; others last weeks or months. The court will tell you at the end of your first day whether you are dismissed, whether you return tomorrow, or whether you have been selected and when the trial starts.

- Jury selection can last anywhere from one hour to most of the day, depending on the type of case and how many potential jurors the lawyers question.
- If you are selected as a juror, the trial length varies widely — you may be done in one day or return for weeks of testimony.
- The court will tell you at the end of your first day whether you are dismissed, whether to return tomorrow, or when your trial begins.
What Happens in the Jury Assembly Room
When you arrive on your first day, you check in at the jury office or a designated desk. You will show your summons and a photo ID. The court staff will take attendance and may show a video about how the jury system works and what to expect.
After that, you wait. The court calls groups of potential jurors to go to specific courtrooms as cases need them. Your name may be called in the first hour, or you may sit there all day and never be called. Bring something to read, work on a laptop, or do — the wait can be long and boring. Most courthouses allow phones on silent, but check your summons for the specific rules.
If you are not called by the end of the day, you will be dismissed and told whether you need to return the next day. Some courts use a one-day or one-trial system, meaning if you are not selected on day one, you are done. Others require you to return for several days or until you are seated on a jury.
Jury Selection and Voir Dire
If your group is called to a courtroom, you will enter and sit in the jury box or in rows of seats. The judge will explain the case in general terms — what it is about, who the parties are, roughly how long it will take. Then the lawyers and the judge will ask you questions to figure out whether you can be fair and impartial.
This questioning is called voir dire. The judge may ask questions first, then each lawyer gets a turn. They may ask about your job, where you live, whether you know anyone involved in the case, whether you have been in a similar situation, or what you think about certain topics related to the case. Answer honestly. Lawyers use your answers to decide whether to keep you on the jury or remove you.
The court will remove some potential jurors for cause — meaning the judge agrees you cannot be fair. Lawyers also have a limited number of peremptory challenges, which let them remove jurors without giving a reason. Once 12 jurors (or however many the case requires) and any alternates are seated, jury selection is over and the trial begins, usually the same day or the next morning.
If You Are Selected as a Juror
Once you are sworn in as a juror, you are bound by the judge's instructions. You cannot talk to anyone about the case — not your spouse, not your friends, not other jurors outside the courtroom. You cannot look up the case online, visit the location where the incident happened, or do any research on your own. You must base your verdict only on what you hear in court.
The trial will have opening statements from both sides, testimony from witnesses, evidence presented by lawyers, and closing arguments. You will take notes if the judge allows it. At the end, the judge will instruct you on the law, and you will go to the jury room to discuss the case with the other jurors and reach a verdict.
How long this takes depends on the case. A straightforward case might be done in one day. A complex civil lawsuit or a serious criminal case can take weeks. The court will tell you the expected length before the trial starts, though trials often run longer than expected.
What to Bring and How to Prepare
Bring your summons and a photo ID — a driver's license, passport, or state ID card. Wear comfortable clothes and comfortable shoes; you will be sitting for hours. Bring something to occupy yourself during the wait — a book, a tablet, headphones for music or podcasts. Check your summons to see whether the courthouse allows phones and whether you can use them in the jury assembly room.
Eat a good breakfast before you go. Some courthouses have a cafeteria or vending machines, but they may be crowded or limited. Bring snacks or money if you think you will need them. If you have a medical condition, medication you need to take, or a mobility issue, tell the court staff when you check in.
Dress professionally but practically. You do not need a suit, but avoid very casual clothes like gym wear or clothes with offensive graphics. If you are selected for jury selection or trial, the judge may have stricter dress expectations, but most courts are reasonable about what people wear on a first day when they do not know if they will even enter a courtroom.
Hardship and Postponement Requests
If you received a summons but have a genuine hardship — a medical appointment you cannot reschedule, a work commitment that cannot be covered, a caregiving responsibility — contact the court before your first day. Call the number on your summons or visit the court's website. Explain your situation briefly. The court may postpone your service to a later date, excuse you entirely, or ask you to serve a shorter period.
Do not straightforward skip jury duty. If you do not show up and do not contact the court, you may face a fine or be ordered to appear in court to explain your absence. Courts take jury duty seriously and have processes to handle genuine conflicts, but they need you to reach out first.
Frequently Asked Questions
Do I get paid for jury duty on the first day?
Most courts pay jurors, but the amount and when payment starts varies. Some courts pay from day one; others pay only if you are selected for a trial. Payment ranges from nothing to $50 per day depending on the court and the length of service. Check your summons or call the court to find out what your court pays.
What if I am not called to a courtroom on my first day?
If you are not called, you will be dismissed at the end of the day. The court will tell you whether you need to return the next day or whether your service is complete. Some courts use a one-day system; others require you to report for several days or until you are seated.
Can I leave the courthouse during the wait?
Usually no. You must stay in or near the courthouse in case your group is called. Leaving can result in a contempt of court charge. If you have an urgent need, ask the court staff whether you can step out briefly, but assume you need to stay put for the entire day.
What happens if I am sick on my first day?
Call the court as soon as possible. Explain that you are ill and cannot attend. The court will likely postpone your service to a later date. Do not go to the courthouse if you are contagious or too sick to sit for hours — courts understand illness and will reschedule you.
Will I know the trial length before I am selected?
Yes. Before jury selection begins, the judge will tell the potential jurors roughly how long the trial is expected to take. This helps you decide whether you can serve and helps the court identify jurors who have scheduling conflicts. The actual length may differ from the estimate, but you will have a general idea going in.
