You are summoned to serve for one day/one trial. The average length of a jury trial in a criminal case is 2 - 3 days, in a civil case 3 - 5 days. If not selected, jurors will be released from jury service as soon as a jury is selected and sworn, usually on the first day.

Grand Jury Terms run for a 3-month period, with sessions about 2 - 3 times each month, usually on Thursday, subject to change. Grand Jurors may be excused for a session, with approval, but are  required to call the Commissioner of Jurors Office to find out the date of the following session.
