Jury Duty Question

Hey yall, I am scheduled for 12:30 today to report for Jury Duty. Is there a reason why it's so late? I've had Jury duty in the past, but the time was 8am.

Also how is the parking situation in the jury garage? Are there spaces available at that time? Or should I park somewhere else? I get very anxious driving around parking garages especially if there are cars behind me.
