    I’m a woman and I have never needed to chart 28 days.

    that screenshot up there reads like some academic person with too much time on their hands trying too hard to congratulate themselves for solving some anthropological mystery.

      But since before you were born people knew how long a woman’s menstrual cycle lasts. Most likely the Internet existed when you became an adult and thought about measuring things. The society you lived in had existing calendars that you were aware of if/when you had a menstrual cycle. You’ve never needed to “chart 28 days” but someone who lived long long ago may have wondered and they would have had no frame of reference so they decided to count.

      Yeah, I don’t get it either. Weren’t most, if not all, ancient calendars lunar based? Far easier to work out a 28 day cycle than a 365.25 day cycle.

      Sandi is a comedian and presenter of UK show QI, not a researcher. She’s literally just talking about an epiphany.

          Believe it or not, in civilized countries it’s common for people to get higher education for the sake of education.

          Her predecessor on QI, mr. Stephen Fry, was also an OxBridge fellow – known as one of Britain’s greatest comedians.

      I’m a woman and I have never needed to chart 28 days.

      Is this because you don’t care when your next period is? Or because you don’t need to record it to remember it?

      I can imagine a modern woman might not care if she always has menstrual products on hand or nearby. But, it might have been more meaningful in ancient times when there might have been more taboos associated with menstruation, plus it might have been more important to know as part of family planning. And, it might have been much less convenient to carry around whatever was needed to handle menstruation.

      Also, in a modern world where calendars are everywhere, I can imagine someone might say “ok, so my next period will be in early July”. But, there was a time when days and months were not tracked, or were only tracked by priests, etc. In that kind of situation, I could imagine it might be useful to count the days until the next period was expected. On the other hand, a primitive society probably spends a lot more time outdoors and sees the moon a lot more often, so it might be just as easy to go “ok, so my next period will be when the moon’s 3/4 full”.

      28 notches means that the bone had 29 sections, which more closely matches a lunar month than a typical menstrual period. But, I could see it being used either way.
