Ttulo: La mayor 💩 de la UNESCO es el DÍA del LIBRO
Descripcin: Do you know that there are 10 days
 that never existed in Spain,
or in France, or in Italy, 
or in almost all of Latin America?
And that UNESCO's biggest screwup
has been marking April 23 as Book Day?
Supposedly April 23 was chosen
because Shakespeare
 and Cervantes died on that day.
Both the same day?
What a coincidence! No?
Well no, because most likely
 they did not die that day.
What happens is that Spain and England
 were governed by different calendars.
How?
So where does our calendar come from?
Well, we can discover
 that information
through something as simple 
as the name of the months of the year...
Hello, good afternoon.
Surely you have heard of the Julian, 
Gregorian, Mayan calendar...
and I could go on like this for a while
because it is estimated that there are
 about 40 calendars around the world.
The one we use
is the one that is now used officially
 in almost the entire world
and is called the Gregorian calendar.
[Dorotea] 
And Gregoriano, why?
 Who was Gregory?
Gregorio*, was a pope from the 16th century,
remember that date.
When I was in Mexico,
 they told me that the Mayan calendar
was so perfect for agriculture
 that many current calendars come from it,
such as ours.
Let's see, this was a bit grating for me,
mainly because Mexico was invaded in 1519.
How can it come from the Mayan if our current calendar
exists since before Columbus invaded America?
Obviously, I investigated it,
 I was not going to remain in doubt
and both he and I were wrong.
No, our calendar does not come from Maya
and no, our calendar is not exactly the same.
In the 16th century, 
when Mexico was invaded,
in Spain we have the Julian calendar
and now we have the Gregorian.
But let's expand this time line a bit:
In the first Roman calendar,
 year 0 is the year that Rome was founded
(with the current calendar that year is 753 BC).
In this first Roman calendar
 there were only 10 months and 304 days
(or 305 depending on the source).
[Dorotea]
 I imagine that September was 
at some point the seventh month,
[Dorotea]
 October the eighth, November 
the ninth, December the tenth…
[Dorotea] 
So, was there also a September, a Quintember…? 
Do you know where I'm going?
Yes, I see where you're going.
In Latin we had these.
We did not have a sextember or a quintember,
but a SEXTILIS and a QUINTILIS.
The etymology of these months is very easy,
it is telling you their order in the calendar:
QUINTILIS is the fifth month, SEXTILIS the sixth,
 SEPTEMPER the seventh and so on up to the tenth.
[Dorotea]
 And the ones from before? 
Will the fourth month be QUARTILIS?
No.
The previous months owe their name to Roman gods.
March comes from MARTIUS,
which is a Latin adjective meaning 'from Mars',
Mars was one of the oldest and most revered Roman gods,
we already find it in the founding legends of Rome.
He is the god of war and vegetation
and we remember that spring begins in March
and spring alters blood
(just like war...).
[Dorotea]
 And what about “April”?
Do you remember this?
- April?
 - Close.
- April?
- Close.
Does "April" have something 
to do with "open"?
Well, it's a theory.
April could come from the Latin APERIRE, 'to open'
(this change from R to L is a common phonetic change
called lambdacism).
[Dorotea]
 But what does "open"
 have to do with the month of April?
Well, the flowers open that month...
But come on, another theory is that it comes from APRILIS,
which just as MARITUS meant 'from Mars',
this would mean 'from Aphrodite'.
[Dorotea] But Aphrodite is the Greek name, 
Venus is the Roman name...
[Dorotea] 
This doesn't add up to me...
Well seen...
The cultural reference at that
 time were the Etruscans,
who lived in what is now Tuscany
and had a civilization supercool.
The Etruscan goddess that 
the Romans equated to Venus
her name was Appru.
So, there you have it.
[Dorotea] 
And May?
May comes from MAIUS,
in honor of Maya
because I have deceived you
 and the Romans were in contact with the Mayans
and that is where our calendar comes from!
What nooooo.
Maya was the Roman goddess of flowering. Spot.
[Dorotea] 
And June what?
June comes from IANIUS, in honor of IUNO, Juno,
the Roman goddess of weddings, of motherhood...
and it seems that it was in this month 
that the festivities in her honor were celebrated.
[Dorotea] 
Okay, but then, 
this was the first Roman calendar.
[Dorotea]
 Why aren't we now in the year…
[Dorotea]
 2776?
Hey?
[Dorotea]
 In mathematics
 you don't have a C2, huh?
Ch…
[Dorotea] 
I mean why our year 0
 is the year Jesus Christ
[Dorotea] 
was born and not
 the year Rome was founded.
Ahhh, well, because later, in the 6th century AD. C.,
a Syrian monk, Dionysus the Meager, began to study the Bible
and other studies and calculated
 the exact date of the birth of Jesus Christ.
He said that it was 754 years after Rome was founded,
so he called that year the year 1 of the Christian era.
(And well, now I feel disappointed,
but now it has been studied again
 and it seems that Dionysus was wrong
and that Jesus Christ was born a few years earlier, about 10 or so).
[Dorotea]
 Okay, and when were July 
and August added?
[Dorotea] And what happens 
with the remaining days?
Well, somewhat later, it is believed that in the VII century BC. C.
Roman astronomers added 51 days 
to the calendar and two more months,
so we had 355 days and 12 months.
[Dorothea] January and February, right?
Exact.
But JANUARIUS ('January') and FEBRUARIUS ('February')
were the last months of the year and not the first as now.
[Dorothea] And why are they called that?
Let's see, January comes from JANUARIUS,
in honor of the god Janus, the guardian god of doors,
the one of exits and entrances
(and that will make much more sense when
 January becomes the first month of the year).
And February comes
 from FEBRARIUS, 'relative to februa'.
Februa was a festival that was celebrated that month.
It was named for the februa
(which is the plural of FEBRUUM),
and the februa were a kind of straps.
A goat was sacrificed especially for these festivities
and straps were made from its skin,
and then some boys used them to whip the girls
they liked as a fertility ritual.
Come on, everything is wonderful.
[Dorotea] 
Oh my gosh…
[Dorotea] 
and when and why did they become
the first days of the year?
Well, it all happened one hot summer afternoon... no...
well, maybe yes, but it happened in the 2nd century BC. C.
[Dorotea] 
And why?
Well, it seems that they advanced
 the elections for magistrates to January 1
and since then, that day was officially
 marked as the beginning of the Roman year.
Later, in the first century B.C. C., Julio César arrives
and 10 days are added to the previous calendar
(that is, we went from 355 to the 365 that we still have today).
[Dorotea] 
Why?
Well, it seems that they were inspired by the Egyptian calendar
(which already had 365 days)
to complete the rotation of the Earth around the Sun.
After Julius Caesar died,
the name of the month QUINTILIS 
was changed to IULIUS in his honor.
[Dorotea]
 And August?
Who came after Julius Caesar?
César Augusto, who was a little envious,
so SEXTILIS was also changed by his name:
AUGUSTUS, which later gave August.
QUINTILIS and SEXTILIS had 30 days,
but two were removed from February, which was left with 28,
and they were put on July and August,
 now each with 31 days.
What we are now left with
 as a result is the Julian calendar
(because the calendar starts to change 
when Julius Caesar was in power).
And the Julian calendar is the one we had when America was invaded.
Very similar to ours, yes, but not the same.
[Dorotea] 
Why isn't it the same?
Well, basically because of leap years.
And the reason they exist
 is hidden in the word MONTH
(well, not exactly, it's to get your attention and stuff).
Month comes from the Latin MENSIS
and means... chan chan chan...
MOON.
You didn't see this coming, huh?
Let's see, do you remember that years
have been added since the first calendar
that only had 304? No?
Well, they were added because originally
the Roman calendar was only lunar,
that's why the months were the moons
(a lunar cycle lasts about 29 days),
so the Roman months alternated
 between 29 and 30 days,
this imbalance was compensated
 because they left adding days,
and days were added because 
the phases of the moon were combined
with the solar calendar until reaching the 365 days
that we have already said that the Julian calendar had.
That calendar was already super-accurate
because it counted on a year lasting exactly
365 days and 6 hours,
but a solar year actually
 lasts 11 minutes longer.
If we are adding those minutes since the calendar exists,
the days are out of balance,
we are going to be on a date that is not 
the one that the calendar really tells us, right?
To adjust this, in 1582 a commission 
of Spanish astronomers was created,
professors of the Salamanca school,
one of the best moments of Spanish
 science and that nobody knows about.
They sent a study at the beginning of the 16th century to the Pope,
the Pope completely ignored them,
and later that same year they sent a second study
and now the Pope, our Gregory, did pay attention to them.
For this reason, it was decided
 to advance the calendar 10 days:
October 4, 1582 became October 15, 1582,
that is, the days from October 4 
to October 14 of that year never existed.
[Dorotea]
 Okay, and what about book day?
The day of the book was chosen on April 23
because that was the day that Shakespeare and Cervantes died
(among others, but mainly these,
which are among the most important in world literature),
but what if they did not die the same? day?
We have just seen that in 1582 10 days 
were removed from the calendar,
but this reform was not applied 
at the same time in all countries.
Only France, Italy and Spain immediately adopted this change.
England did not do so until 1752.
Almost two centuries in which Spain
 (the country where Cervantes died)
and England (the country where Shakespeare died)
had different calendars,
that is, English was 10 days behind Spain's.
Shakespeare died on April 23,
but for Catholic countries he died on May 3.
VERY STRONG, HUH.
