      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.

    Fun fact: Sweden decided in 1699 to gradually change from the Julian to the Gregorian calender, by removing the leap day over 11 leap years. In 1700 they did this, but in both 1704 and 1708 they FORGOT to remove the leap day (well, the Great Northern War was raging, so I guess they were busy with other things). In 1712, they gave up and ADDED an extra day in Febuary to get into face with the Julian calender again, thus creating the date the 30th Febuary 1712. In 1753, they removed 11 days in one go and finally made the switch.

    Julius Caesar as Rome’s head priest was in charge of adding the extra days, but as he had been busy conquering for over a decade, he had forgotten to do it.
    This resulted in an incredible scenario where he managed to cross from Italy to Greece to chase Pompey, because Pompey’s navy tought it was the winter and winter crossings were almost impossible, so they stopped blockading the sea and went ashore. It was actually late autumn and Caesar was the only one to know this, so he crossed unopposed and went on to crush Pompey.
    So tldr; Caesar probably won the civil war due to a calendar drift that was his fault.

      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

      Caesar was in charge of calendar but this is so oversimplified it’s inaccurate. I think long correction can be found in Askhistorians Reddit sub about this. But overall people were able to tell time even without official calendar and Caesar had a habit of starting his wars unseasonably soon (you waited till spring so you could feed the troops) and more importantly Caesar’s proconsulship wasn’t over yet. So the Senate didn’t expect him to start moving his troops so yearly. But it isn’t something to do with the calendar.

      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.

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.

    Fun Calendar fact! Many languages associate the days of the week with the 7 "classic" Celestial bodies. Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn. There's remnants of that in English with Sunday, Monday, and Saturday-the other days are named after Norse gods (but gods that align with the Roman gods. Mars = Tyr gods of War, Mercury = Odin trickery gods, Thor = Jupiter gods of thunder, Frig = Venus goddesses of fertility). This is generally Latin in origin but the most interesting thing is that Japanese also draws the same association. This is assumed to be tied to Europe, but unlike other loanings they don't use the Roman gods, but instead directly translate to their names for the planets, which are all named after the 5 Chinese elements. Fire, Water, Wood, Metal, Earth.
    However, China doesn't use these names for the days. They do for the planets, but last I checked, they just number the weekdays.
    Anyways, Japan's adoption of the 7 day week is an intersection of the two outside cultures most influential on them, China and The West.

    So the orthodox church still uses the Julian calendar to calculate easter. Does anyone know why they didn’t see the shift in days as a problem?
    The calendar in the Orthodox Church is a weird thing. Like the Greeks and Romanians will calculate Christmas with the Gregorian but Easter with the Julian. And the Russians and Serbs use the Julian for everything, which is why they celebrate Christmas January 7th. Which is still December 25th on the Julian calendar. And the Armenians use the Gregorian calendar but rather than celebrate Christ nativity the 25th the group it with epiphany, his baptism which is the 6th of January.
    There’s rumors the Greeks will move completely to the Gregorian calendar next year on the 1700th anniversary of the council of Nicaea .

    This is because the ancient Persian/Zoroastrian calendar was also solar. Norooz, the biggest holiday of the year for Persian-related groups, also originates from Zoroastrian and ancient Persian traditions.

    The indigenous people of New Zealand (tangata Māori), use a lunar calendar system called “Maramataka”. Each day of the lunar cycle has a name, and an associated energy level, high energy: a time for productivity, low energy: a time for rest and recovery, and neutral (each adapted day by day according to weather, social needs, etc).
    The year is measured not by the solar rotation, but by the emergence of the Pleiades star cluster (called Matariki) (some Iwi/tribes use different star markers based on how easy it is to see the constellation, as we have had to adapt it from our ancestors farther north in the pacific), a custom seen throughout the pacific. Because Matariki disappears for some time at roughly autumn - early winter, its return is actually a highly accurate annual marker (due to its presence being based on the rotation of earth).
    Because the calendar is loose, Matariki is both a very long celebration (lasting multiple weeks) but is calculated in accordance with Maramataka. The last quarter of the moon cycle since the rise of Matariki is considered the start of the new year, and celebrations begin. It is a time for mourning those who have passed, setting goals and wishes, and spending time with family.

    The other problem with the roman calendar was that the only one who could add the days was the Pontifex maximus. And if that Pontifex maximus was to say, get in a campaign for ten years like Caesar, the current Pontifex maximus did, no one could modify the calendar, elading to a two months difference between the roman calendar and the actual solar year, the Romans believed it was still august, when it was october.....

    Fun fact: Some calendars use the "metonic cycle". It's a calculation that shows that every 19 years, the same date of a solar year will fall on roughly the same lunar phase (+- 1 day).
    So this is a way to have lunar months and intercalary months and still keep track of solar years, even if it's a bit complicated.

    Eh Matt Parker's video on the topic was much better. Caesar's original calendar had a leap day every 3 years instead of 4, this was later corrected by Octavian/Augustus. The Gregorian calendar is needlessly complicated. We actually need to have one fewer leap day every 128 years but apparently Pope Gregory thought it wouldn't be easy to keep track of that. So instead came up with multiples of 100 and 400. The 128 calendar is orders of magnitude better. It loses one day every 625,000 years as opposed to the Gregorian's ~3000.

      Ok! Just chatted with Rob and he says it was actually more difficult choosing between historical events for specific days, as opposed to not being able to find something that happened on a day. The example he gave was events like Christmas often causing people throughout history to do big things on that day which lead to a bit of a traffic jam in picking what to include.
