Rome had 8 day weeks.. actually the history of the Roman calendar is fascinating: https://en.wikipedia.org/wiki/Roman_calendar#Nundinal_cycle https://en.wikipedia.org/wiki/Roman_calendar#Nundinal_cycle "Because the term of office of elected Roman magistrates was defined in terms of a Roman calendar year, a Pontifex Maximus would have reason to lengthen a year in which he or his allies were in power, or shorten a year in which his political opponents held office. For example, Julius Caesar made the year of his third consulship in 46 BC 445 days long."
