On what days does the US Supreme Court hear oral arguments?

The US Supreme Court hears oral arguments three days a week, on Mondays, Tuesdays and Wednesdays from 10:00 am until noon (and occasional afternoon sessions from 1:00 to 3:00) in two-week rotations, called "sittings." The justices meet to discuss and vote on the cases on Thursdays and Fridays.

They write opinions and conduct other business of the Court on the two "off" weeks when arguments are not presented.
