Oh, pardon me, Mr. "Let's ration everything", but what d'you think we're floating on? Don't you know the poem? "Water, water, everywhere, so let's all have a drink."
- Homer Simpson (not Samuel Taylor Coleridge)
Saturday is lördag in Swedish and was named for washing up. The lör part is originally from the Proto-Germanic word Laugr which means water or water torture. In English the day was named for the planet Saturn which was itself named for the video game consule. Just kidding (HA!), it was actually named for the Roman god of agriculture and harvest and justice and strength. Saturn was pretty much the Supreme Ruler of the Omniverse but he was also a bit of an asshole (which maybe goes hand in hand). He castrated his father Caelus and ate his own children to prevent them from fucking with him (although Jupiter survived, and did indeed fuck with him later on. So one might argue that Saturn was right to try and eat his kids). Incidentally, in Babylon he was called Ninib. Incidentally again, Saturnalia is feast and also a dinosaur.
According to ISO 8601, Saturday is the sixth day of the week, although some contrary Jews and Christians refuse to follow the standard. Throw them to the Lions!
