Wednesday, << WEHNZ dee or WEHNZ day, >> is the English name for the fourth day of the week. This day gets its name from Woden, or Odin, the chief god in Teutonic mythology, to whom it was sacred. At the beginning of the Christian Era, the Germans called the day Woden’s-day. Its name later changed to Wednesday. The first to name the days of the week after gods in mythology were the ancient Romans. They called the fourth day of the week after the god Mercury. From this name, the French called Wednesday mercredi. See also Ash Wednesday; Odin; Week.
