According to The Scrum Guide, "The Daily Scrum is held at the same time and place each day . . . to inspect progress toward the Sprint Goal and to inspect how progress is trending toward completing the work in the Sprint Backlog."
What about the day of Sprint Planning? We don't really have a Sprint Goal or Backlog until the end of the day. Do we just not have Daily Scrum on this day with Sprint Planning essentially taking its place?
