On the first day you report, you will be requested to be at the courthouse at 8:00 a.m. for jury orientation. Depending on how many cases are going that particular day, you could be at the courthouse until 4:30 p.m. - 5:00 p.m. When you are serving on a case, the hours are approximately 9:00 a.m. - 5:00 p.m. (depending on the judge).
