You will be happy to know that I used your video as an educational tool to teach my grandson about the history of the modern calendar. This is something that they didn't teach him in his 6th grade class experience. Thanks for posting this great lesson.
Julias modeled his calendar after the Egyptian calendar which had 12 thirty day months and a extra bonus month with 5 days. He took the bonus month and scattered its days into the other months but also took days off Feb because Romans believed it to be an unlucky month, Feb was then used for the leap day every 4 years. Julias took the control of the calendar out of political hands and that was a pretty big deal.
The extra five days in the Egyptian calendar were for celebration. It seems more logical to me that each month should have an equal number of days so I liked your idea of "scattering" those five days.
This is a really well put together video!! My man was ahead of his time!!
The entomology of the names of the days of the week in different languages is interesting. May I add to your comment by comparing English & Spanish
Monday - Lunes (Both from the moon)
Tuesday to Friday, just replacing Roman gods names with Norse gods names
Saturday & Sunday in English still trace back to the names of celestial bodies, but in Spanish they have religious roots
Sabado - Sabbath - The Hebrew Day of Rest
Domingo - The Day of the Lord

If anyone finds your pace too fast - thats what RePlay is for! I LOVE LoVe your work. * Simply brilliant *
Good work. Once small error. You refer to .25 day as "a 25th of a day" when it's a fourth of a day.
One quarter*
yep, 1/4
Tanja 1 fourth= 0.25
1 25th=0.04
@7salad3salad no that's not how it works. They both add up to 100 but a 25th is 0.04 while a fourth is 0.25
"Mayan calendar prophecy for 2012 debunked..." ** everyone looking at the Ethiopian calendar that states today as 2012... lol
Happy New Year🎉, we made it into 2013 today. As an Ethiopan I'm happy to see 2013 and the world still exists.
It's also insane the rest of the world agreed to leap 7 years to appease the Catholic church and thinks Ethiopia is behind. We're actually the accurate.
@@ninagolgi3132, Okay let's all use your calendar then. But I also heard that your calendar doesn't have a year 0 as well so can that be fixed?
@@seanvasquez523 Nor did the Julien calendar... or the gregorian one.
Lol the “end of the world “ as we know it
All those people calculating 2013 miscalculated. It’s actually supposed to be 2046 not 2012 for the Mayan long count
The number of days lost in a year due to the shift into Gregorian Calendar is 11 days. For 268 years using the Gregorian Calendar (1752-2020) times 11 days = 2,948 days. 2,948 days / 365 days (per year) = 8 years.
So as of now 2020 were actually in 2012
Wait what? If we lost days that means that it is 2028 already right? Or I'm just dumb 🤣
So if we go back and use the julian calendar we will gain 11 days per year right? Not the other way right? I feel stupid right now 🤣
People living in Britain, America and other English colonies went to sleep on the night of Sept. 2, 1752, and when they woke up the next morning it was Sept. 14, 1752. Because the people thought the government was trying to cheat them out of 11 days of their lives, there were riots in villages. Eleven days (Sept. 3-13) were cut from the calendar, deleting them forever. These days simply never existed - no births, no marriages, no deaths.
This was very confusing by itself, but added to this change was that New Year moved from March 25 to Jan. 1. Think how confusing this must have been to people used to thinking about a year running from March 25 to March 24, now they had to get used to the year running from Jan. 1 to Dec. 31. Imagine - a person could have been married on April 26, 1710 and died on Feb 2, 1710.
This is a problem that has also confounded genealogists for many years.
Among the last countries in the world to accept that they were using an inaccurate calendar were the British. On the Julian calendar, named after Julius Caesar, the year would be 365 days and 6 hours long. That calendar was officially adopted in 325 A.D.
This Julian system, based on the movement of Earth around the sun, created a 365-day calendar year with a leap year every four years and a New Year’s date of Jan. 1. The system was widely adopted, but over time the New Year slipped to March 25 to correlate with the Christian holiday, Annunciation Day (March 25 is nine months prior to Christmas).
As it became possible to measure the length of the solar year more accurately, astronomers found that the Julian system exceeded the solar year by 11 minutes, or 24 hours every 131 years, and three days every 400 years. This excess amounted to 10 days between 325 A.D. and 1582 A.D.
Several centuries later, Europe begins to realize that the Julian calendar system had not perfectly calculated leap years and had caused the calendar dates to become out of sync with celestial and religious events.
In 1582, Pope Gregory XIII refined the Julian calendar mathematically to fix this mistake and created a new system that we now know as the Gregorian calendar. Most of the world jumped forward by 10 days on Oct. 5, 1582, restoring the vernal equinox to March 21.

But England, unhappy with the Church of Rome, refused to go along with the new calendar. In the mid-18th century the difference had grown to 11 days. All British lands except Scotland, which changed its calendar 100 years before, now celebrated New Year’s Day on Jan. 1.
Some of this is factually inaccurate, like Julius didn't create the Julian calendar, he made its extremely similar predecessor, Augustus tweaked it and named it in Julius's honour (and named a month after himself cos why not). And the early Roman calendar didn't have 12 months, it had 10 months starting in March and ending in December, when they ran out of months they simply waited until the next year started to start the calendar again, the extra 2 months and the intercalary month were added later, and January was made the first month centuries after it was added to the calendar and centuries *before* Julius's time.
Just putting this out their but that 'guy from the middle ages' wasn't from the middle ages. Richard III lived in the early modern period. He was born on the 2nd of October 1452 and the middle ages ended on the 29th of May 1453 with the fall of Constantinople and the official End of the Roman Empire.
What year is it?
History: *Yes*
365 days at 1440 minutes per day is 525,600 minutes but at 360 days it is 518,400 minutes. Subtract the difference and we are left with 7200 minutes. Which is what they have added every year since 0AD. When we calculate the difference May 5th 2022AD is actually January 1st, 2000 AD. The real Y2K.
Our time run in multiple of x60 x60 x12
1 second x60= 60 seconds (1min)
1 min x60= 60 min (1hour)(3600sec)
1 hour x12= 12 hours (720min)(43200sec)
12hrs x60= 720 hrs(30 days)(6weeks)(1month)
1 month x60= 60 months (5yrs)(1800days)(360weeks)(43200hrs)
60 months x12= 720 months (60yrs)(2160days)(4320weeks)(518,400hrs)
720 months x60= 43200 months (3600yrs)(259,200weeks)(1,296,000days)(10divine yrs)(9 BakTun)(1 Saros Cycle)
3600years x60=216,000 years (600 divine years)(540 BakTun)(60 Saros)(2,592,000 months)
600 divine years x12= 7200 divine years (100 Great Years)(6480 BakTun)(2,592,000 years)(720 Saros)
100 Great Years x60= 6000 Great Years (432,000 divine)(388,800 BakTun)(4320 Saros)(360 Kali)(180 Dwapara)(120 Treta)(90 Satya)(36 Mayamuga)
6000 Great Years x60= 360,000 Great Years (25,920,000 divine)(259,200 Saros)(21600 Kali)(10800 Dwapara)(7200 Treta)(5400 Satya)(2160 Mayamuga)

That is one complete cycle.
Wake up people. We are being lied to.
02:07 The graphics are wrong but the narration is right.
In the old Roman calendar the 5th to 10th months were just named after numbers
Quin - Five -> (Quins, Quintet) Quintilis, renamed July in honour of Julius Caesar
Sex - Six -> (Sextet, Sextuplets) Sextilis, renamed August in honour of Augustus Caesar
Septem - Seven -> (Septuagenarian, Septuplets)
Octo - Eight -> (Octopus, Octagon)
Novem - Nine -> (Nonagenarian, Nonagon)
Decem - Ten -> (Decade, Decimate)
Thanks for explaining this.
As always, I am in awe. Cusdos. New words in my vocabulary. Mother would be so proud.
I am from Ethiopia now we are 2008 Christmas merry ... january 29
Ignores most people calling themselves Orthodox Christians continuing to celebrate according to the Old Calendar.
The more calender we have, the more new year celebrations we have.
i read somewhere about a new calendar where everything is regular and where the year ends with a 'new years day' without a name, so every monday of every month is the 1st and every 3rd wednesday of every month is the 17th. I found this very smart but i can't find it anymore!
Search youtube for "dave gorman calendar"
You may be referring to the World Calendar, though I can't really be sure what you are saying.
does anyone really know what time it is?
It's January 4th, Happy 2021 (:
ye
@easalle I see what you are saying. Looking back I would have given a quick explanation about how Mayans couldn't graph the non-ending calendar of time with their limited amount of stone. I did add an annotation to a video that covers this.
thanks for this video,i have to do a presentation about calendars in class and this was a tremendous help, thanks again.
Me too but im from brazil c:

Timekeeping is a fascinating occupation. Getting the Earth diurnal rotion to 'sync up' with the Tropical year has been a bit of a chore. Of course, there was no ention of all the modern efforts to standardize clocks or the International dateline...maybe another video?
You need to play this video at x0.25 speed to make any sense of what is being said.
He doesn't know the nature of youtube.....PERIOD.
This videos editing was ahead of its time. Bravo.
@6nz6slayer6 The theory that the Mayan calender ending = the end of the earth is bunk. The mayan calendar is just a way of measuring time.
The first dissed information at 0:40 the rest is irrelevant. “The calendar” is not simply the calendar otherwise wouldn’t be here.
Wow never noticed the rest of the months names are so obvious, SEPTember, NOvember, OCTober, DECember,
just like in Chemistry and Music Theory
1:56 janesh God of beginning, soooo similar to ganesh in Hinduism prayed for same
@dawgama4 Thanks. I wasn't copying CGPGrey's style though, I was doing stuff like this before I knew about him. :-)
Great music and great narration. And for kids, if it's too hard, give them your cell phone and have them re watch it.
They can listen to Post Malone, they can follow this.
Actually, the Mayan calendar aligns nearly perfectly with what Rome called Neptune to complete an orbital, marking what I would deem an eon (about 900 some odd earth years) by that, I believe next we should adopt that for accuracy rather than continued use of a pseudo diety
@allaboutmath
Yeah, and how can it possibly be changed? The Earth spins around 365 times in the time it takes to go round the sun. Thirty days hath September, April, June, and November. That's not that hard to remember and the calendar works.
nice. How do folks make these kinds of vids-what software is being used?
If the Romans had kept their 8-day week, they could have used it to create a solar calendar of 331 days by counting a certain day of the week only 1/4 of the time. And this would have been shockingly accurate, drifting by less than a day per millennium, with no need for leap years.
Not bad for a quick bite of history though some things need more research. Also, nothing should be called "bunk" without a bit of explanation. Hope to see another high-speed video bit on the Mayan calendar just for kicks.
The planet-hours of day algorithm to explain the days of the week is INCORRECT. It is supposed to start with a sequence of planets (Saturn-Jupiter-Mars-SUN-Venus-Mercury-Moon) originating in Ptolemy's Almagest (Book IX). However, the modern sequence of days of the week was already in used in the Baths of Titus previous to Ptolemy's birth. Not only that disproves it, but moreover, that heliocentric initial order was allegedly taken by Ptolemy from the oldest widest Chaldean astronomers according to the speed of planets. Unless Babylonians had an Heliocentric view of solar system they could not know they sidereal periods. Why should Greeks and Romans adopt a geocentric view if ancient astronomers had a heliocentric one? Why did Ptolemy pick up such an order overcoming the contrary views of famous Plato, Archimedes or Eratosthenes?
What if Venus was in a different location, so that it would explain its current placement in the days of week?
Wow short and educational in just three minutes man he's better than most teachers
Thanks! After Effects.
It is funny that March used to be the 1st month of the year in the old style calendar and so on.
I know it's not explicitly said but the video really sounds like you're suggesting Muslims were following a 7-day week during Roman times. Considering the Western Roman Empire fell before Islam was even a thing that could be quite misleading for some people.
Totally did not mention aryabhatta who was the FIRST human to accurately measure planetary movements and revolution cycles. Bhattacharya, who invented the number ZERO. Both critical to calenders
Wait, if the gregorian calendar subtracted 10 days from the Julian calendar, which was about 365.25 days in a year, then whats the explanation for why the gregorian calendar has 365.2425 days in a year?
Valerie Wong
Because just by subtracting 10 days alone, after 1700, the calendar will go wrong again.
Are you sure that the year started starting on January 1st before 1 AD? Because I'm pretty sure that the English still had the year start on the 25th of March until September 14 1752.
This is true. In England the tax year used to start on March 25 because that was the 1st day of the Year. When we lost 11 days it moved to April 6th. It is still April 6
It has come to my attention that the year DID start starting on January first before 1 AD, but that many European countries changed the start of the year to varying dates in the Middle Ages.
@@viquezug3936 the year did start on January 1st. But January 1st was on the date that is now March 25th. The new year then began just after the spring equinox whereas now it starts just after , 11 days after the winter solstice. This is in England
@@michaelsrowland Source, please?
@@viquezug3936 you already stated in your first comment that the year started on what is now March 25.
Did you guys know that when we got this calendar in the 1500’s we lost 8 years in the translation so basically it’s no 2020 it’s 2012
Explain

OMG! So, Newton (my favorite scientist of all time) was NOT born on Christmas Day, but rather on Perihelion Day-even better!
The narration is correct! Septem means 7, octo means 8, novem means 9 and decem means 10.
This is when March was the first month
8 year old video and this much quality.
@ojfoggin Yea...I sometimes mix up number and time measurements. *almost* say 0.25 instead of .25th...oh well.
Really liked the video, learned a few things. I know you don't want to produce a 25 minute video, but it would really help the slower people such as myself if you didn't speak so quickly. great job!
Very interesting but a little tip would be to talk a slower to allow people to absorb and think about what's being said...
Just keep pausing the video
Great video until you said 2012 is a bunch of bunk, as 2012 is Ethiopia year, so as of now 2020 we are really in 2012. don't meant to be rude just wanted to say great video, and I know you did this back in 2011, so you just have to see what is happening to the world right now and I don't need to explain. thank you
You're absolutely right!
Wow this is what my school picked. epic
Happy New Year 2021!
this was pretty good man nice job!
A good try/start but some of your information is way wrong. For example, the current days of the week (as we know them) were not named after the Roman names of planets/gods, but rather based mostly off of Norse gods. If you are going to say that Tuesday is named after the god Mars, it might help to say that Tuesday in latin is "dies Martis". Do some research or at least make sure your information is presented more clearly. Also .25 does not equal 1/25.
After knowing the fact that earth never comes to the same place again,as sun is also moving around the centre of the galaxy
Are you sure it's a bunch of bunk?
2:12 You didnt explain how November is now 11th month instead of 9th and December is 12th instead of 10th month etc...
ΩmG Gaming they used to be, when March was the first month.
Then a new thing happened & was put into effect in January, so they started the year then.
@danaross this is extremely inaccurate historically. the present length of the solar year and the number of months wasn't used until one of the popes. and october, way back then was the 8th month. it was during this rearangment by a pope that it got shifted into the 10th month slot
1:17 small mistake. 4th of a day, not 25th.

Saw this on the Daily What Blog. Great Job. Subscribed.
can someone explain me how did julius cesar know a year was 365 days when he didint know at the time how many days did the earth need to rotate around the sun?
MrMarioSm Stars change their position everyday. If the stars went back to their "starting" positions, then a year has passed.
I must admit that I thought that about the Mayan prediction of 2012 being the end of the world being not a plausible idea. The Mayans would have had a different interpretation of dates and times.
Who is watching this in 2018?
It really helped me a lot!
@ZackLawrenceShow Disappointed that they aren't sticking to pushing certain beliefs? the whole BC/AD system was flawed from the beginning since it was based on an event many don't believe even happened and of those who do, they disagree when it actually did. Plus this video is about how our calendar evolved from many different forms so it seems pretty fitting.
They have 8 day a week? Huh....kinda weird when you think about it.
I am a musician specializing in classical music. If you use Beethoven`s music as background music, I cannot focus on what you say at all... Good background music should be the kind that does not drag our attention with it.
Wouldn't call 2K12 a bunch of bunk 2012 was the end of the world and the beginning of the Aquarius Age
Rome had an 8 day cycle?
Nice video! I wish my college lectures were this rapid. It would be easier to stay awake :)
Fantastic! I learned alot! Thank you and happy new year.
Vewry interesting! Some stuff I did not know or understand before.
Good job
You didn't explain why they changed from 10 month calendar to 12 month
What is the reason for Jan 1 being Jan 1 in the gregorian calendar? Why not the day after the winter solstice?
Pity you don't understand decimal fractions. 0.25 is not, as you said, a twenty-fifth. It represents 2 tenths and 5 hundredths. This simplifies to one quarter.
What about the book of Enoch. It describes the making of a calendar year including leap year.
So the Greeks got their calendar from the Egyptians right?
very well articulated! thanks alot!
I wish there was no background music
Aren't the days of the week named after Viking gods? E.g.. Thursday for Thor, Friday for freya... I read this somewhere
But when did we start the whole bc ad thing
YesHua is KING!
Great video! Very clear! What software to make it did you use? :)
Very very interesting. Thanks for the upload.
Very good explanation.FYI, Julius Caesar was seen as a living God a Christ.He was "messing up with the stars" & was descendant of MAIA (Venus the Life giver or Vagina in the Sky)
Gaius (son of the earth)Octavius Caesar who became Augustus(exaltedChrist) was seen as the Son of God in Heaven(Divus Iulius=Julius Caesar)
Everything in the Roman Empire depended on religion & GODS so the calendar had to be precise to Talk to them.CaesarChrist change it from lunar to Solar.Hence July & August.2 gods
