My family is listening to the Purim story and in it they mention that the Persians didn’t have a seven day week
I thought everyone had a seven day week all the way back from creation
Anyone know of this source?
Wikipedia “Week”, and scroll down to “Achaemenid period”. Seems like the last week of the month (reading Wikipedia (unreliable), and I’m no expert) could have more than 7 days until the next month started.
