"The ancient Romans would occasionally add an extra month between February and March." Ah yes... Smarch.

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.

"Correcting time? But that is an impossible task, your Holiness!" - A friar towards the Pope. "I got special people to help me...". - Pope Gregory. (Time Squad theme starts to play)

For further ‘reading’, I recommend the Historia Civilis video “The Longest Year in Human History”. He goes in quite a bit more depth on Caesar’s impact on the calendar, including some fun anecdotes.

6:07 looks at the top right of the screen Was it Walpole? Me: wheeze

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.

"Thank you, animated Matt". Ok, it's official: In the EH "lore", there are two Matts, and one of them is animated.

Everybody have a good day!

Once watching this video, I remembered that I am in fact am in the People’s Republic of China because I’m a day later.

I spent 10 minutes of my day for an elaborate add? Im not disappointed!

thinking that using a riddle for a sponsor????? YOU GUYS DID IT AGAIN😂😂😂😂

OK, OK, been a fan of the channel for ages, so I got the community level - I owe ya that. Keep perks, this is a shoulda done it thing. Worth it to ease my conscience. No more freeloading for me.

Not mentioning the Salamanca University, the one that literally created and helped intituting this calendary is kind of crazy ngl

I'm surprised you didn't mention the Hebrew calendar, a luni-solar calendar with a 19 year cycle of 7 years of intercalated leap months that was created in order to keep Passover during the spring, the inspiration for Christianity's Computus. 12th century rabbi Maimonides noted the ancients also realized that the solar year must be slightly less than 365.25 days and presented the calculations of his contemporary Muslim scholar Avempace to prove it.

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 .

Didn't even wait for the credits to finish rolling before backing the calendar. Looking forward to it. Would be interesting to know what was the hardest day to find an event for was?

I LOVE your use of the word "fix" for this subject, because he didn't just resolve the problem with the Julian calendar, but he FIXED the measurement of days in a year in the sense of setting it and locking it in place!

Ah the story of how a bunch of Monks hammered out the calendar.

Correction: The Orthodox Church DID NOT adopt the Gregorian Calendar. They employed a Serbian scientist called Milutin Milanković to make their new calender, it is called The Revised Julian Calendar. It is more accurate than the Gregorian calendar because it uses modern measurements. Currently the 2 calendars are the same but the Gregorian Calendar will become innacurate in the year 2800.
