The ancient Babylonians, then the Romans, named the days of the week after planets and other bodies they saw in the sky.
|Sunday: Sun's day
|Monday: Moon's day
|Tuesday: Tiu's day; Roman god of war.
|Wednesday: Woden's day; the Roman god Mercury became the Scandinavian god Woden. The day of Mercury was translated as Woden's day.
|Thursday: Thor's day; originally the day of Jove became Thor's day. Thor and the roman god Jove (Jupiter) were gods of thunder.
|Friday: Freyja's day; the day of the planet Venus was translated into Freyja or Frigg's day because both are goddesses of Love.
