“When it got to be time to design the week—a period of time, unlike the day, month, and year, with no intrinsic astronomical significance—it was assigned seven days, each named after one of the seven anomalous lights in the night sky. We can readily make out the remnants of this convention. In English, Saturday is Saturn’s day. Sunday and Mo[o]nday are clear enough. Tuesday through Friday are named after the gods of the Saxon and kindred Teutonic invaders of Celtic/Roman Britain: Wednesday, for example, is Odin’s (or Wodin’s) day, which would be more apparent if we pronounced it as it’s spelled, “Wedn’s Day”; Thursday is Thor’s day; Friday is the day of Freya, goddess of love. The last day of the week stayed Roman, the rest of it became German.”
