At the "last week" level, assuming we don't keep track of today's date, wouldn't it be good enough to see in the date if it's in the same month or not, and eventually see if it'rougly at the beginning, muddle or end of it ?

If you were told something was uploaded on 2023-10-02, with just the average feeling that we're currently around the middle of the month we'd know the video is roughly a week or two in the past.
