Days of the week
Date from Anglo-Saxon times i.e. prior to the Norman invasion of 1066. Sunday is the day of the sun, Monday is the day of the moon. Tuesday is the day of Tiwes or Ties the old Germanic god of war who was identified with the Roman god of war Mars, which is why Tuesday in French is mardi. Wednesday is the day of Wodin, sometimes Odin, the Old Norse deity who was identified with the Roman god Mercury, which is why Wednesday in French is mercredi. Thursday is the day of Thor the Old Norse god of thunder. Friday is the day of Frigg, the Old Norse goddess who was the wife of Wodin. Saturday is the day of Saturn and along with Sunday and Monday are the three days of the week named after heavenly bodies, the other four are all named after old Germanic/Norse deities.
