Saturday is officially the 7th day of the week, but I don't think anyone cares past the fact that most people are having a day off on a Saturday.

We can thank the Roman god of agriculture Saturn and the Norse trickster god Loki for Saturday. It comes from the Saxon Sæter-dag and Danish Saturdag; Saturn's day.

After his son Jupiter chucked him out, Saturn went to live with Janus and introduced agrivculture and viticulture, bringing a new age of peace and prosperity. His feast day is known as Saturnalia and Saturnmalia, celebrated on December 17th is known for giftgiving, tomfoolery and sometimes debauchery, hence being considered by Christians to mean orgy. The customary greeting for the occasion is "Io (yo), Saturnalia!".

It is considered that when the Christians chose December 25 as the birthday of Christ in 4th century AD, it was to eliminate an already popular pagan holiday whilst Christianising the people. The medieval festival "the Feast of Fools" was a continuation of Saturnalia in the Christian era.

In his "Epistulae morales ad Lucilium", Seneca the Younger in about 50AD wrote
"It is now the month of December, when the greatest part of the city is in a bustle. Loose reins are given to public dissipation; everywhere you may hear the sound of great preparations, as if there were some real difference between the days devoted to Saturn and those for transacting business....Were you here, I would willingly confer with you as to the plan of our conduct; whether we should eve in our usual way, or, to avoid singularity, both take a better supper and throw off the toga."

Go the Romans.
