The Reason We Have 7 Days in a Week

How did we get the days of the week? Neil deGrasse Tyson and comedian Chuck Nice break down the planets of the ancients and how they correspond to our days of the week.

How many planets were there to the ancient Greeks and Romans? Learn about the meaning of the word “planet,” the names of the days, and how we got seven days in a week. Plus, learn how Copernicus later discovered a planet that was right under our noses.
