The Perfect Calendar & Elizabethan England’s Secret Plan To Weaponize It

Vote for this video by social sharing!
The calendar we use today is flawed, it loses a day every 3300 years. About 20 years ago I was told a story by Duncan Steel about a secret plan In Elizabethan England to deploy a new, better calendar to weaken the Pope and the Catholic Church. The work originated with Simon Cassidy, a calendar researcher who threaded together calendar design, the work of John Dee and England’s attempts to Colonize the Americas in the lat 16th century.

I’m not saying this is true, but it’s a fun story that explains a bit about the astronomical and ecclesiastical origins of the calendar we have today

    Not a story I normally click on but seeing it was from you I had to. As it turns out it is totally what I am interested in. Keep it up Scott.

  2. Mark McCulfor

    congrats on one million subs Scott!! You’re one of my favorite youtubers ever! I’ve been watching since you’ve had 300,000 or so subs! Keep up the amazing videos!!!

  3. TriVyte Official

    Love you Scott, fantastic video as always.

  4. Blinkxxx123xxx

    Hello Scott, I wish you a beautiful new and successful New Year. And I’m really looking forward to your other great videos!

  5. Sven Felsl

    The Misses did good!!!

  6. Arizona TV

    Congrats to 1M, Scott! Enjoyed your speech as always :)

  7. Kenneth Compton

    I had never heard of John Dee until two days ago, in the video game Nioh, of all places, and now you’re referencing him. Isn’t there something that defines previously unknown knowledge appearing multiple times in quick succession after the first learning of it?

  8. Mort Kebab

    Ah, if it’s a record perihelion then that might have contributed to the fires in Oz.

  9. TonyP

    Congrats on the 1M subs :)

  10. Ted Cameron

    All the best for the next decade :~) Hope all was good over the holidays. :~)

  11. Live The Future

  12. Rob Buchanan

    Love the Iranian calendar caviat!

  13. BnORailFan

    In short, we’re now in the roaring twenties! I just hope it doesn’t end like last century’s (The Great Depression).

  14. Michael-John Mushill

    Loved it!

  15. Joseph Kane

    OOOOOH! “… back when I wouldn’t diss astrologers…” Now that is a memorable quote!!!

  16. Paul Haynes

    In a parallel universe, the number of days divides exactly into the length of a year, and the value of pi is exactly 3.
    And we have twelve fingers.

  17. Pezz Pezzer

    Sooooo Scott, where did you get the Gunstar? Is that a 3D print job I am guessing? Very awesome and quite subtle in the background there.

  18. Kestrel16C

    Last time I checked you didn’t have 1 mil. subsribers, congratulations.

  19. Railgap Esoterica

    Q.E. loved the D.

  20. Lynx Issiodorensis

    Intriguing detail from the history.

  21. Meat Fractals

    Congrats on 1M subs Scott! I love this channel and love watching it grow! Thanks for EVERYTHING!

  23. Péter Szabados

    I’m Scott Manley, sail safe!

  24. Dave Williams

    “he was an astrologer back when *I* wouldn’t diss astrologers” <-- what's with the *I* ? Are you Emperor Palpatine/wolverine/Thanos or something?

  25. Tentoes

    Emergency ski vacation? Pretty rough time, there!

  26. David Willis

    Weaponized calendars… I like that phrase!

  27. Jared Z

    12020 HE my dudes

  28. Ricardo Becerra

    UK was already brexiting 🤷🏻

  29. Tristan bar Avraham

    That was outstanding. Thank you for posting that. Oddly enough I was trying to figure out how to add the Hebrew calendar to Outlook and ended up here. I hate forgetting to fast on the 10th of Tevet and figured no problem. I have been an IT person since ‘95 and somehow forgot how tortured online paths can get 🙀 so this was a wonderful break.

  30. Linecraftman

    What the hell is that shirt 😂

  31. Edward Downer

    100 years later they established my home city Kingston, Jamaica. Coincidence? I think so, without a doubt, since it’s further from 77W than Spanish Town.

  32. Guardsman Miku

    This isn’t even the first time calendars have been weaponized.
    Ever wonder why Julius Ceasar of all people invented a calendar? In his earlier years Ceasar was in charge of adjusting the pre-julian calendar when it fell out of line, and when fighting the civil war he used his knowledge of what season it actually should be to out-smart his opponents who’s calendar was out of line.

  33. Brett Perry

    2020 Is a new decade, it’s a part of the twenties. Decades run from jan 1, xxn0 to dec 31 xxn9. Year zero thing only applies to centuries and milenia.

  34. Robert Anderson

    “Skiing” got it.

  35. Gary Hendrick

    10:38 East coast ;)

  36. nathancd

    Blew my mind at the end there. Well, really through the whole thing, but ya, that last part.

  37. Billy Grant

    Luv the vids,informative and easygoing, keep em coming.

  38. Eugene Weltzer II

    10:38 West Coast?

  39. Gregory Lewis

    Wow. That was really interesting! Somehow I think I’ve been screwed out of some overtime by us using the wrong calendar!

  40. Michael Moorrees

    12:15 – 77 degrees, should get the Flat Earthers’ conspiracy senses twitching.

  41. bazoo513

    Absolutely fascinating! I barely heard of John Dee before.
    (BTW, glad to see that none of your limbs are encased in plaster or some more high-tech means of immobilization (o: )

  42. Mr T

    I want the days that were stolen and started April Fools back.

  43. Bitchute is better than Youtube

    You were in Armagh? Dam. Hope your enjoyed it. Thats my neck of the woods

  44. MrTrilbe

    missed opportunity to sa something on the lines of “I would say happy 2020 but it’s still 2019 and happy christmas eve”

  45. Sean McDonough

    2:31 – Not to be confused with the _Siberian_ year, which is a measure of GULAG prisoners’ sentence lengths.

  46. Al T

    Yes! Starting 2020 with the old intro! And it’s fine…sometimes you just need an emergency ski vacation.

  47. bimblinghill

    Unexpected subject, but absolutely fascinating!

  48. Sky Bound

    77deg West is somewhat a spooky coincidence but interesting nonetheless. Love the history nuggets, especially from old England where she ran and changed the world

  49. James Simmons

    If we really applied Milankovitch cycles to our calendars I wonder what the taylor series look like :-)

  50. mVm MotoVlogMusic

    I won’t comment until my heads stops spinning…

  51. Chris Coreline

    Oh heck you were at Armagh Observatory! i remember that place as a ween.

  52. Jim's videos

    Do you mean to tell me you built a time machine…… out of a Gregorian??

  53. AnimeSunglasses

    After the last few days’ news, I’m laughing desperately at “CAUTION: Only applies if you’re using Iran’s calendar”…

  54. Chris Norman

    Had to go skiing. Rough life Scott, rough life :P

  55. dosmastrify

    4:50 how did they know to do all this?!

  56. Ninilium

    10:39 Um, East Coast!
    (I got your back Scott)
    Excellent “Off Tangent” video.

  57. Ryben Flynn

    Spring starts on March 19th. this year.

  58. Ficon

    This is Assassin’s Creed worthy!

  59. vdiitd

    12:26 I see what you did there. 😏😏

  60. ebikeracer9

    this was really interesting!

  61. Jetman640

    6:50 anyone going to point out Calendar is spelt with a K and an E there.
    no shade, just thought it was interesting so figured I would throw that out there.

  62. J. Morris

    Mind you, all these calculations were done before spreadsheets!

  63. Matthew Chenault

    Are we going to be talking about the all-powerful, history-defining Virginia Man?

  64. Michael Gallagher

    Sure Scott, “My wife said I had to go skiing cause l was too dam tired”. Sounds a bit like the dog ate my homework!
    And now it’s just blame the wife! I like it 😆

  65. Mar

    I have to confess that I love that sort of thing. conspiracy-history-maths-science-church ..perfect.. it’s like a better version of the da vinci code. now I have to go watch these movies again.

  66. Sean McDonough

    10:33 – Also, longitude was _far_ from easy to calculate accurately back then, meaning that they could have easily ended up seizing a piece of the Spanish Caribbean, possibly at great cost in blood and treasure, and gone to all the trouble of building a meridian observatory on it, only to find that, oops, they grabbed _the wrong longitude._

  67. Richard Shipp

    Only Scott can talk 20 minutes about calendars and make it interesting

  68. nick l

    I feel like it’s been a decade sence your last video lol😁

  69. White Brad Bad

    You look refreshed and upbeat, Scott! I think the missus’ insistence was well worth it.

  70. Slightlylyons1

    Any time Dr Dee comes up it’s going to be weird.

  71. StaticSkyTV

    “Emergency ski vacation” … you are indeed a fortunate man.

  72. Conrad T. Pino

    Minor “west coast” misstatement at 10:38 mark.

  73. Anis Optera

    Hey it runs straight through Jamaica. What better place to start a glorious tropical colony for her majesty.

  74. Eric Ferguson

    My head hurts from all this thinking. I need to go skiiing.

  75. Ahmed Ouyad

    Congratulations for one M subs!

  76. DenseAlloy

    The question is did George Washington know about this since he laid out the District of Columbia?

  77. Just Looking

    Interesting. definitely some “National Treasure” level information there.

  78. Risa Bear

    “England, sorry” … this guy really knows his stuff.

  79. Sean McDonough

    5:55 – Nitpick: what King Henry wanted (and eventually got, no thanks to the Pope) was an _annulment,_ not a divorce. An annulment voids the marriage retroactively (so that the parties to the annulled marriage are legally considered to have never been married in the first place); a divorce ends the marriage but does _not_ void it (so that the parties to the divorced marriage are legally considered to have previously been married, but to no longer be married at the present time). Having his first two marriages annulled until one of the wives produced a persistent male heir allowed him to disinherit his elder daughters in favour of his (eventual) younger son (not that it prevented either of said daughters from winding up with the throne in due course anyway); his last two annulments were for other reasons (annulment three happened because it just didn’t work out, although they remained close friends until he died, while annulment four happened because the female party was cheating on him).

  80. OtherTheDave

    0:08 Your wife seems like a wonderful person 😃

  81. PsychoLucario

    John Dee was a really strange man, like your small bit doesn’t even scratch the surface.

  82. jdjeep98

    “if that doesn’t get your conspiracy theory antenna twitching, I’m not sure what will” ROFLMAO

  83. Perpetual Bystander

    I’m Scott Safe! Fly manly! 🚀

  84. Misa Nikolic

    Perhaps there is still some evidence to be found in John Dee’s secret burnt-out lab in the south of France…

  85. Lovecraft

    Something to add: There’s a general problem with dates in the primary sources, as many important events have conflicting dates given. Sweden actually adopted the Gregorian calendar, but then the King became Lutheran and switched back to the Julian calendar.

    Science101 exam question.
    1. How 1 year got its 365 days? Please elaborate.
    Scott Manley: ……sir, could i have another answer booklet please.

  88. Jed Anderson

    As a history nerd, I highly recommend reading “The Watchers: A Secret History of the Reign of Elizabeth I” by Stephen Alford, which goes into fascinating historical detail on the Elizabethan intelligence complex and the conflict with Catholic Europe. I first learned of this calendar issue in that book.

  89. Tetsujin

    6:22 – He was an astrologer before it was not cool

  90. CrazyJohnsonBoys

    “Caution: Only Applies If you’re using Iran’s Calendar.” ;)

  91. Laélien Rivière

    Just a message here: thank you Scott, for everything. Your videos got me more seriously into KSP, pushed me back to my studies, and made me the Space system engineer I am now. I am so very glad to see you achieve 1M subscribers, and for you to keep true to yourself and all. Also for being one of the coolest nerfs around, and an inspiration for us all.
    Fly safe, for a long time still!

  92. Jonathan Tanner

    Thank goodness you’re back, I’ve been struggling to know how to fly

  93. James Hoiby

    “I’m going to out-geek you all.” That didn’t need to be said. I assumed it before I clicked on the video.

  94. Arild Schönberg

    Skiing with the wifee is an important part of any marriage.

  95. Jackalovski

    “yesterday we had earth move through it’s closest perihelion in a century” Which probably didn’t help Australia one bit

  96. Nicholas Chaplin

    I need an emergency ski trip

  97. Charles Wilton

    If you poke around Washington, DC with Google Maps to see what structures lie precisely on longitude 77 W, you find. . . guess what. . . the Basilica of the National Shrine of the Immaculate Conception. The Catholics did an end run around John Dee’s wicked plan!

    The question in a Bar Trivia session about twentyyears ago “what happened between Sept 2 and Sept 14 in 1752? When I answered “Absolutely Nothing”, you could have heard a pin drop. . .

  100. Ryben Flynn

    Well, the only real solution to an accurate calendar is to adjust the Earth’s rotation and orbit to exactly be 24 hours and 365 days.
