The Calendar's 10,000 Year History | World History | Extra History 

It’s my birthday

How did these ancient cultures know how long a year was? They didn’t have modern instruments to measure earth’s place, so I’m wondering how they knew.

This going to be good hoping link to Julian calendar

Can’t wait for that calendar.

For fence03: Anthropologist here. You do not need 'modern instruments' to measure earths place to determine how long a year is. As in - according to you and your specific cultural group. As is pointed out in this video, many past ancient cultures had their own calendars, or at the very least an understanding of time/a year progressing. Star positions, moon phases, equinox events, seasonal migrations, animal and plant life cycles, there are many ways to make measures of the passage of time, and, over 100's if not 1,000's of years, those measurements get refined into that culture's' understanding on the passage of time. Many ancient cultures and groups had (and still have) staggering complex understandings of these subjects and it is very incorrect to assume that just because they did not have the same technologies as modern times that they could not possibly understand the passage of time, or conceive of a the concept of a year. As is addressed in this video, there were (and still are) many different ideas about exactly how many days should go into a year - and this is culturally (and geographically determined) - there are some excellent academic and popular literatures out there that cover this idea - and your question - and I encourage you to explore this further if you are interested. Maybe ask a local librarian if there is a library near you and see where that takes you.

30 days hath September April June and November All the rest have 31 Except when Leap Year doth come by Give to February 29 Or in Sweden in 1712 17 plus 12 = 29 29 + 1 other twenty-nine = .......30? Did it maths? 🫣

Wow

​@darthparallax5207 I donno of that's right but props man.

What if February 30/31 existed?!

January 0 February 30/31 May 35 December 31.5 GMT December 32

I hear it has lousy weather.

Do not touch. - Willie

Good advice!​@@wikiuser92

My favorite time of year!

Fmarch*

Great. You just made me remember the intro song. Electric banger.

@@Primus1243 That's a nostalgic rush!

Most relevant time to quote this: through God all things are possible, so jot that down

And oh boy, it was a long year!

That was the first time I saw Matt’s face, face reveal jump scare lol

TWAS HIS GENIUS PLANNING MY LAD

oversimplification, they knew the seasons were a bit out of alignment from the official date, but merely didn’t understand the specifics as WELL as Caesar did, and underestimated just how FAR off it was.

This story is actually just a myth, there is little to no actual sources to back it up and in fact we have issues knowing when exact Caesar set sail particularly because the calendar being used wasnt exactly defined so it’s not even certain Caesar set sail at what Roman’s thought were midwinter It makes sense too if you think about it because ancient people weren’t stupid, their livelihoods quite literally relied on them knowing how the seasons worked, they weren’t stuck thinking it was winter even though it was warm out just because the calendar said so. If Caesar knew the calendar had drifted so would have a massive segment of the population and it only would have impacted the hosting of religious and holiday festivals On top of all this Romans could actually sail in winter, there were ships and captains for exactly that purpose and it’s like Caesar used these experts to sail. On top of this Caesar didn’t escape unscathed, he was caught by Bibulus days after setting sail and had some of his ships sunk All in all it’s a common internet myth but not actually true at all

Howdy

Thank you and same to you

You’re very kind but I’m in England. I have other plans

Imagine waking up that one particular morning and you find out it's now ten days later. "Man, how much did I drink last night?"

Windows calendar only goes back 100 years :(

My calendar on apple just says: “1, 2, 3, 4, 15, 16, 17” for the fist week of the market

It literally doesn’t. On an iPhone, anyway. That’s five minutes of my life lost. 😂

@@MissusDelaneey Try to look on the internet. But sorry for the time 😂👍

Thank you so much, the crew appreciates it all the help!

@@extrahistory I will say, no offense intended, that I thought Matthew was a bit older. In a good way, great pipes! I thought the artwork was doing him, er, um, favors, but if anything the art was what made me think that in the first place. Hey Matt, I'm older than dirt (we were standing around, and God said, "I think I'll make dirt". We were like "You sure Boss? Isn't that going to be a bit....messy?". He said "I'm gonna do it". We said, "Hey, you da Man, God! (geez, the dry cleaning bills..) so good on you brother

They didn't even acknowledge that you could measure a primitive day from sunrise _or sunset._

Same 😓

Unfortunately, they would've been heckled out of the conversation if they tried. Due to the rampant Anti-Semitism going on right now.

Fun Fact: Salamanca University was named after Hector Salamanca, beloved uncle of famed philanthropist Tuco. Rumor has it, if you stand just outside the campus Los Pollos Hermanos at noon you can still hear his bell chiming.

They didn't mention non of the institutes or mathematicians or members of the papal commission for the calendar, not the ones who reviewed it. Besides the Salamanca U proposed the change twice with their opinion (as many people had done, though not as professionally) but the actual final calendar was based on the designed by Aloysius Lilius and factchecked by Cristophorus Clavius who stablished the final draft. I'm not saying the mathematicians of Salamanca didn't influence the development of the calendar, they did a lot, but many people did and non where credited. So I don't see why the special credits.

He didn't mentionned Sosigenes either, the alexandrian astrologist that designed the julian calendar for Caesar, based on the egyptian calendar ^^

@@d.esanchez3351 Se constituyó la "Comisión del Calendario", en la que destacaron los astrónomos Cristóbal Clavio[7] y Luis Lilio. Clavio, quien pertenecía a la orden jesuita, era un reputado matemático y astrónomo a quien Galileo Galilei requirió como aval científico de sus observaciones telescópicas. En cuanto a Lilio, sabemos que fue el principal autor de la reforma del calendario. Murió en 1576 sin ver culminado el proceso. En las Tablas alfonsíes, realizadas por iniciativa del monarca Alfonso X de Castilla, fue asignado al año-trópico un valor de 365 días 5 horas 49 minutos y 16 segundos el cual fue tomado como correcto por la Comisión del Calendario. Pedro Chacón, matemático español, redactó el Compendium con el dictamen de Lilio, apoyado por Clavio, y se aprueba la reforma el 14 de septiembre de 1580, para llevarla a la práctica en octubre de 1582. Literally where the creators and the biggest country to institute it at the time, helping it being use globally, that's why the especial shout out would have been appreciated

​@@krankarvolund7771 But he did... He's even illustrated at one point!

😅😂

Edit At mount " Athos" the monastic self governing region They actually use the byzantine day schedule that makes things even more weird for the uninitiated ones 😁

Correction, none of Orthodox Churches moved to Gregorian calendar. Those that abandoned Julian calendar, switched to Revised Julian calendar, which is even more accurate than Gregorian (and essentially the same for next 800 years).

@@player1_fanatic oh really?? I got look this over.

It's not Gregorian, it's reformed Julian calendar - it's different from Gregorian, made by astrophysicist Milutin Milankovitch.

They remind me of Kurzgesagt

THIS. It irritates me so much when I immediately think October is the 8th month, only to recalculate that it's the 10th >_

How did you exclude SEPTember

Patreon

Btw if they make it make sure to include the Armenian genocide

Mustafa Kemal Ataturk

Outlawing the Fez should be a disqualifying factor

They need to make a Lafayette series.

That's a show I wanna watch!

Thanks! A lot of love has gone into it!

David made a special one just for it! It turned out AMAZING!!

@@extrahistory thanks for replying :]

You thought it was The Pope. But it was me! Dio! (Yes, I know Stone Ocean is more fitting, but damn do I hate Pucci)

@@messey12 His JP VA is Domon from G Gundam.

To make the prayers and fasting dynamic. Ramadan fasting is not stuck in one season. It comes in all seasons over 36 years. That's my guess

Settled agriculture peoples throughout history tend to favor the solar calendars, which usually add smaller numbers of days every few years. A few use(d) lunisolar calendars, where the months are actually tied to the lunar phases, i.e. a new month starts on the new moon, but they add a whole leap month every several years to keep them in general sync with the solar agricultural cycles. Semi-nomadic pastoralist cultures, unlike settled agriculturalist ones, tend to have purely lunar calendars, like the Islamic calendar. The Arabian peninsula was never a breadbasket of agriculture and the people there never needed to keep their year in sync with the solar agricultural cycle. When they conquered and colonized the many settler agricultural cultures they did, they kept their lunar calendar for religious uses and used the preexisting local calendars, which by then were mostly the Julian calendar of Rome, for practical agricultural purposes.

Partially it was because the month of Ramadan was meant to be full of fasting, prayer, and charity towards the poor and the starving. Poverty happens all year 'round, therefore Ramadan should too. Outside of that, I dunno. Probably a high mined middle finger to Rome.

Arabs used lunar calendar somewhat similar to chinese and jewish calendar. but mohamed removed the 13th leap month turning islamic year into what it is today.

Because those people are backwards, and they remain backwards.

Yes

Yes

kings were elected in some cultures

time traveler you

Does that include or exclude antipopes and other instances of multiple claimants?

That is, of course, if you don't include Discordian popes. Everyone is a Discordian pope.

Just a wall calendar but maybe next year if we decide to make a calendar again.

Thanks!!! David is going to be so excited you said that

@@extrahistory I meant to say hard, is there anywhere i could find said image without the logo on top of it? if that exists

No he is actually a time lord from doctor who

You can do the math if you want. Bur keep in mind that the date of Easter isnʼt tied to a specific day in a month but is defined (iirc) as the first Sunday after the Spring equinox or something I donʼt know

@@deutschermichel5807 The new calendar differs by three day every four hundred years. The algebra is obvious. Why do you think Pope Gregory changed the calendar by nine days?
