I mean, if today i.e. is Sunday then someone long time ago should have said “Today will be Sunday” for the first time in a period from today that is multiple of seven. I was assuming that it was Pope Gregory XIII in October 1582, but looks like he is not. I failed in googling and duckduckgoing out the answer, so I ask for Lemmy’s collective wisdom!
EDIT: so question is not about the origin of 7-day week and sequence of weekday names, but about the exact reference point (day) of today’s weekday countdown. From when have people stopped adding or ommiting any adjustment ‘out-of-week’ days (like in Babylon or Rome) and kept counting to seven till today? In other words, there should be a point exactly N x 7 days ago from which the 7-day countdown has not been interrupted. Or at least the earliest known day in history that everyone on Earth agreed upon as a reference point
EDIT 2: Solved by https://lemmy.world/comment/1852458 Thanks everyone!
I believe most weekday names as we know them in English and many other northern European languages derive from the vikings.
Monday = Moon day. In Spanish, it’s “lunes”.
Well, the question is not about the origin and sequence of weekday names, but about the first day in history of uninterrupted count of 7-day cycles which leads to today’s state of the week. Added this to the post.
Saturday is Saturn’s Day
“Saturday” references to the planet “Saturn”.
Here is a video about the origin of the weekday’s names in different languages: https://www.youtube.com/watch?v=gifimOF5a_U
I addition to that, here is a video which explains how the months got their names: https://www.youtube.com/watch?v=Y9iOt48bTw4&list=PL5x1QB-VRuDtHCWcuSx0DgJr2mnuNXkSB&index=4 This channel has very interesting videos about the ethymological origins of different things. It’s worth watching.

Saturday in nordic languages Lördag/lørdag is simply lögardagen, the day in the week when you took a bath.
I believe the Vikings adapted them from the Romans. The Greeks and Romans also had a day for the Sun and a day for the a Moon. They obviously never changed the Month from their Latin roots. July and August are named after Julius Caesar and Caesar Augustus.
Don’t know about Saturday, but “lørdag” comes from the Norse word for “washing day” because the vikings were surprisingly hygienic for their time, and bathed/washed themselves once a week.
