Why does everyone use a 7 day week, and where did it come from? Where do the names of the days come from? And who can we blame for Mondays? Here’s the true story of one of the oldest human customs still in use today. It gets a little weird.

    Sometimes simple questions don't have simple answers, huh? I'm on Twitter and Instagram so tag me and tell me what you thought of this video! @DrJoeHanson @okaytobesmart
  • Joe went mad after being calm exactly after 7.7 minutes! 7:42=7.7 minutes, that's the reason why SEVEN is sooo unique
  • @jorjeezealien
    You mentioned mensuration, and it's honestly a good theory of why specifically 7 days (rather than the number 7 itself) would be important to people before math and astrology. I mean, if half of your people bleed for about 7 days for reasons that are unidentifiable to you, you might consider it important to take note of. Especially if you noticed it happened to cycle with the moon.

    This is a pretty damn good video from a theatre perspective. It's like watching one of the countless maniacally insane conspiracy theorists online these days - except this time, ironically, it's entirely based in solid math, science, and history. That said, from a teaching perspective, it's a little too hard to follow compared to your other videos. I worry that this is what I might look like at the front of the classroom when I'm low on sleep and having a bad day.
  • @puremath3491
    the best part is that he began his descent into madness just after SEVEN minutes
  • He tried to look like a “lunatic”. Haha. Get it. Luna as in moon. Ugh, never mind.
  • I didn't knew when this educational video turned into a psychological documentary
  • @gobias_
    This was an absolute tour de force. I was almost missing the information cos I was fascinated by the performance.
  • @buco4526
    He went ”I don’t need sleep, I need answers” mode
  • @kittybeans8192
    Fun Fact: Joe said "Seven" seven times in this video! And about 93 more times too after the first seven.
  • @HeroOfLight13
    That second half of the video was like a bizarre fusion between Charley Day's conspiracy theory board scene and Milo's opening lecture to an empty room in Atlantis: The Lost Empire, I love it. XD
  • @renesongs
    A captivating presentations of the origins of the 7 days of the week. I recently did some research on the origins of the 7 notes of the major scale in music and stumbled on the same the 7 gods of both Babylon and Hellenistic Greece. Incidentally there are also 12 possible motes names in western music but that is for a different reason.
  • @physicsgirl
    I want a GIF on repeat of 12:28. Nah, GIF isn't right, because we need that sound too. 10/10 noises.

  • @mpatricksc
    In Portuguese the names of the days are "simply represented by numbers" too: Segunda - second day Terça - third day Quarta - fourth day Quinta - fifth Sexta - sixth Then you have: Sábado, which I believe has something to do with "shabbat"; Domingo, I just learned from your video, something to do with Dominici. Amazing video by the way! I love your channel
  • I first watched this video when it first came out. It’s still one of my most favourite things on the internet 🥰
  • @aloemoss6985
    Anyone else been watching him slowly lose his mind during quarantine and then he pulls this out
