what is the origin of the phrase at sixes and sevens
At sixes and sevens An ancient dispute between the Merchant Taylors and Skinners livery companies is the probable origin of the phrase.[1] The two trade associations, both founded in the same year (1327[2]), argued over sixth place in the order of precedence. In 1484, after more than a century and a half of bickering, the Lord Mayor of London Sir Robert Billesden ruled that at the feast of Corpus Christi, the companies would swap between sixth and seventh place and feast in each other's halls. Nowadays, they alternate in precedence on an annual basis.[1][2]
Names of the days of the week Between the 1st and 3rd centuries, the Roman Empire gradually replaced the eight-day Roman nundinal cycle with the seven-day week. Our earliest evidence for this new system is a Pompeiian graffito referring to the 6th February (viii idus Februarius) of the year AD 60 as dies solis ("Sunday").[1] Another early witness is a reference to a lost treatise by Plutarch, written in about AD 100, which addressed the question of Why are the days named after the planets reckoned in a different order from the actual order?.[2]
