How far back in history do you have to go before the days of the week (monday, tuesday, etc) no longer line up... in other words, how long have we been consistently keeping track of days of the week as a society before it breaks down...
@freemo most probably the recorded history will stop with the Babylonian
@sgul @freemo Wikipedia says 7-day "weeks" go back to Babylonia, including one day a week for making offering to the gods and avoiding prohibited activities.

Of course, other systems since have used different approaches including the French Revolution attempting to create a decimal calendar of 10-weeks.
Most calendar systems are lunisolar with the sun's position determining year length and the moon's phase determining month length. Reckoning weeks was more or less optional and of little interest.
And since prehistory is, by definition, before anything was recorded we can only speculate from limited findings how, or even if, time was recorded. It seems likely that some tribal leader made scratches on something to tally lunar months and maybe solar years.
@lePetomaneAncien @sgul @freemo iirc (no I'm not really that old) the Babylonians also had multiples of 60 which still reflected a bit into some of our recent systems like seconds and minutes and degrees.
