If you are selected as a trial juror, your service will generally be the length of that trial, which may take between one and five days, or in some cases longer to complete. If you are not selected as a trial juror, your length of service may also vary depending on the case. There may be circumstances where your jury selection may be for a future trial date. The normal working hours of the courts are 8:30 AM until 4:30 PM. However, if you are selected on a trial you may stay later than 4:30 PM.
