From GypsyWolf

Saturday is the last day of the week, corresponding to the Roman Dies Saturni, or day of Saturn, the Roman god of death and agriculture, also known as Chronos or Cronus (Greek).   Saturday is the seventh day, therefore the true “sabbath day”, appropriate for the home and rest.   Saturday is also represented by Loki, the Norse god of tricks and chaos, brother of Odin and god of fire.
