Saturday is the day of the week between Friday and Sunday. It is the either the sixth or seventh day of the week as discussed below. Jews and many Christians believe God established the 7-day weekly cycle at Creation as read in Genesis chapter 1 and 2.

"Saturday" is a single by Fall Out Boy released from their 2003 album Take This to Your Grave. It is still incorporated into their set lists and is almost always played last at their shows, with very few exceptions. The lyrics were written by Patrick Stump. Patrick said that this was the song that he worked hardest on.

Saturday (Oooh Oooh!) is the 4th single, released on December 11, 2001, off Ludacris's album Word of Mouf. It features Sleepy Brown.
