Weird but true history: Why the calendar skipped from October 4th to the 15th in 1582

Those 10 days simply don’t exist…sort of.

Annie Reneau

If you think crossing time zones and navigating Daylight Savings Time can be confusing, imagine losing or gaining multiple days just by crossing a border.

That was life for Europeans in the late 16th century after 10 days were eliminated from the Gregorian calendar. In 1582, if you lived in a Catholic country, the calendar went from October 4 to October 15—the dates in between just didn’t exist. As a result, you could find yourself going back or forward in time simply by entering or exiting a non-Catholic country.

What happened to the missing 10 days in October of 1582?

The mystery of the missing days isn’t so much a mystery as a miscalculation. For nearly 1,600 years, the Julian calendar had been used by people across Europe, and on the surface it wasn’t a whole lot different than the Gregorian calendar we use today—365 days in a year with a leap year every 4 years and the spring equinox being placed on March 21.

But there was one problem: It was off on how long a solar year is by 11 minutes and 14 seconds.

That may not seem like much, but after over 1,000 years, it added up. Placing a leap year every four years without exception meant that the equinox was slowly pushed back on the calendar. By the mid-1500s, the equinox fell on March 11 instead of March 21. As a result, the calculations for Easter were thrown off.

How the Gregorian calendar recalibrated the spring equinox

After years of consultations among church leaders about how to fix the problem, Pope Gregory XIII signed an edict implementing a new calendar system—the Gregorian calendar we use today—in February of 1582. As part of the implementation, 10 days were removed from October during weeks that wouldn’t affect any of the Christian holidays to get the equinox back to March 21.

But losing those days wasn’t seamless. For one, since the change came from the pope, non-Catholic countries weren’t too keen on taking up the new calendar. Austria, Spain, Portugal, Italy, Poland, and the Catholic states of Germany switched to the Gregorian calendar, but Protestant and Orthodox countries of Europe resisted. They all came around eventually, but it took more than 100 years for the British Empire to jump on board, and some countries, including Russia, Turkey, Greece, Albania, Lithuania, and Estonia, didn’t make the switch until the 20th century.

In the meantime, the removal of October 5 to 14 meant that dates were different in different countries—and in some cases even within the same country. Germany was split by Catholic and Protestant regions, so the two different calendars made travel between those regions really weird date-wise. (Imagine trying to navigate that kind of chaos in today’s global neighborhood. Good thing they didn’t have airplanes then.)

Leap year calculations in the Gregorian calendar are a little more complicated

Now, one might ask, “If the Julian calendar had a leap year every four years, didn’t that account for the length of time in a solar year? How is that different than the leap years we have in the Gregorian calendar?”

The answer is that the way leap years work in the Gregorian calendar is a bit more complex than many of us realize. Most of us were taught that we have a leap year every four years, which is generally true, but with some regularly scheduled exceptions. We don’t hear about these exceptions because they happen so infrequently and won’t happen within our lifetime, but they make all the difference mathematically.

In the Gregorian calendar, we add a day to the calendar (February 29th) every four years except on years that can be divided by 100, which are not leap years, unless the year can also be divided by 400, in which case it is a leap year. That might sound confusing, but essentially, 1700, 1800, 1900 were not leap years, but 2000 was. The years 2100, 2200 and 2300 will not be leap years, but 2400 will be.

Removing those leap years every 100 years but not every 400 years accounts for the miscalculation in the Julian calendar, just as removing the 10 days from October of 1582 fixed the drift that had occured over millennia because of it. There are still different calendars used in different places for different purposes, but the Gregorian calendar has gradually become the international standard for dates and times.

Time may be a construct, but humans have managed to construct quite a detailed system of measuring it, even with some quirky bumps along the way.

These demonstrations drew 100,000 people in 40 cities across the country. In New York City, David Miller, a young Catholic pacifist, became the first U.S. war protester to burn his draft card, doing so in direct violation of a recently passed federal law forbidding such acts. Agents from the Federal Bureau of Investigation later arrested him; he was tried, found guilty, and sentenced to two years’ imprisonment.

22 million took part in the National Moratorium, a protest against the continuing war in Vietnam. This was an effort by David Hawk and Sam Brown, two anti-war activists, to forge a broad-based movement against the war.The organization initially focused its effort on 300 college campuses, but the idea soon grew and spread beyond colleges and universities. Hawk and Brown were assisted by the New Mobilization Committee to End the War in Vietnam, which was instrumental in organizing the nationally coordinated demonstrations.

One of the largest of the many events involved 100,000 people converging on Boston Common, but activities nationwide also included smaller rallies, marches, and prayer vigils. The demonstrations involved a broad spectrum of the population, including many who had never before raised their voices against the war. This was considered unprecedented: Walter Cronkite (then CBS news anchor) called it “historic in its scope. Never before had so many demonstrated their hope for peace.”
Later, a declassified Kissinger (then Nixon’s National Security Advisor) file revealed that these protests discouraged a plan by Nixon to use nuclear weapons in Vietnam.

A dark week for Ukrainian journalism by Anastasiia Lapatina

And, the Ramstein meeting gets postponed because of Hurricane Milton.

Read on Substack

This week was a dark one for Ukrainian journalism. 

On Oct. 9, Ukraine’s leading news outlet Ukrainska Pravda (UP) said the President’s Office was threatening their work by exerting “long-term and systemic pressure” against the newsroom. 

UP said Zelensky’s office was blocking government officials from talking to the outlet or taking part in its events, as well as pressuring businesses to stop advertising collaborations with the outlet. 

“These and other non-public signals indicate attempts to influence our editorial policy. It is especially outrageous to realize this at the time of Russia’s full-scale invasion of Ukraine, when our joint struggle for both survival and democratic values ​​is extremely necessary,” UP said in a statement.

The statement also referenced the outright disrespectful exchange between Zelensky and UP’s star political reporter Roman Kravets during a press conference in late August. The President was visibly annoyed with Kravets, interrupted him, and eventually accused the outlet of having a secret agenda to undermine him with negative coverage. 

It’s worth noting that all governments, even democratic ones, try to control media narratives and restrict access to journalists. All those anonymous American officials giving comments to journalists without authorization risk getting fired when doing it, for example. 

However, what is happening to UP is worse than just normal politics. Pressuring businesses to stop collaborating with the outlet directly undermines UP’s ability to stay afloat, at a time when advertising already plunged because of the war. 

To be frank, apart from being objectively worrying, this situation is also quite embarrassing. Every public-facing Ukrainian spends countless hours persuading the world that Ukraine is a democratic country that’s defending European values and is worth the world’s help. Why the Ukrainian government would shoot itself in the foot when the world’s patience and money for Ukraine are running out is a mystery to me. 

Yet this wasn’t even the worst piece of news. On the next day, we learned that Ukrainian journalist Viktoriia Roshchyna died in Russian captivity.

She was only 27, and was supposed to be included in the upcoming prisoner exchange, the government said. She was reportedly held in a brutal detention facility in the Russian city of Taganrok, known for its torture of prisoners. 

I never met Viktoria, but her former colleagues say she was the embodiment of her profession – brave and determined, always the first one at every scene, working and bothering editors about her work 24/7. 

She was taken captive while reporting from Russian-occupied territories in August 2023. But that wasn’t her first time in Russian captivity. 

Viktoria was first detained by the Russian Federal Security Services (FSB) for 10 days in March of 2022. To the dismay of her colleagues, she was trying to get into occupied Mariupol, which was being obliterated by Russian fighter jets back then. 

“Nothing could stop Vika if an idea was born in her head. Nothing was more important to her than journalism,” her former colleague Yevheniia Motorevska wrote on Facebook. “She was a force of nature that we failed to tame.”

On the geopolitical front, Ukrainians were disappointed with the postponement of the Ramstein group meeting because of Joe Biden’s preoccupation with Hurricane Milton.

The Ramstein group—which is called the Ukraine Defense Contact Group but steals the name from Germany’s Ramstein Air Base, where its meetings happen—is a coalition of more than 50 states who militarily support Ukraine in its war against Russia. 

The group was scheduled to meet this Saturday, Oct. 12, at the level of state leaders, for the first time ever. Zelensky hyped up the meeting beforehand, saying it would be “special”, while the media reported that President Biden may even be ready to advance Ukraine’s NATO bid before he leaves office, perhaps making significant decisions during the Ramstein.  Biden was supposed to chair the meeting. But it didn’t happen: The US President had canceled to stay in the US and deal with the hurricane.

With Ramstein postponed indefinitely, Zelensky went on a European tour with his “victory plan”, presenting it to leaders of France, the UK, and NATO.

Presidential Office advisor Mykhailo Podoliak said on Saturday that the President might reveal the plan to the Ukrainian public within days. I’ll keep you updated as soon as that happens.

That will be it for today. I’ll be back next week,

Cheers, and Glory to Ukraine

— Yours Ukrainian

Work to focus on engaging communities during the energy transition

(It can’t hurt to put bits like this out into the universe. Somebody’s working on this, and more people ought to. So a nice little discussion of what’s working is appropriate. -A)

October 11, 2024 ARC Laureate Fellows

This Cosmos series on Australian Research Council Laureate Fellows 2024 reflects excellence from world class researchers in Australia.

Chris Gibson is a Senior Professor in the School of Geography and Sustainable Communities at the University of Wollongong. For his ARC Fellowship, he is investigating how decarbonisation impacts Australian regions.

Professor Chris Gibson: finding a truce in the climate wars.

Decarbonisation and energy transition are at the sharp edge of a hot political battle. There is a lot of dispute over new technologies like offshore wind, and exactly what mix of energy we need. It’s like a second iteration of the climate wars. But after a decade of stalled policy on climate, we have to embrace the decarbonised future, whether we like it or not. It’s an issue that needs to transcend the political divide.

But we’re faced with a dilemma: we need urgent change, but urgent change rarely occurs, if ever, in a way that is fair. The burdens and benefits of change are not distributed equally across society. And the quicker the change, the more risks there are. Regions can be all too easily left behind.

Geographers think about how substantial change, like this energy transition, affects communities. We think of ourselves as an integrative discipline. We bring together expertise from across environmental science, economics, social geography, legal geography, and from experts who are good on governing transitions. By stitching together insights from all directions, we try to see the bigger picture.

My ARC project is aiming to put together a systematic understanding of what’s happening in decarbonisation, both from the top down, with a nationwide view, and from the ground up, about how people in different regions are responding to change.

We’re putting together a team to look at how decarbonisation hits the ground in different regions, and how it affects different workers, different industries, what kinds of opportunities come out of that, what kinds of changes are needed, how communities and households are responding to the decarbonisation challenge, and how a First Nations’ perspective can lead the way.

Community responses have to be taken seriously. It’s too easy and too convenient to cast aside sceptics as “nimbies” (Not In My Backyard) or selfish or ignorant. If you take the time to hear the diversity of opinions that come from communities, you’ll often find that people are worried about real issues, with valid concerns. Local communities are very knowledgeable about their patch, and have a capacity to understand what kinds of changes are needed. If we can forge a more inclusive process that brings regional perspectives, skills and experience to the forefront, we reduce the risk that regions are left behind. And governments might actually see regional communities as an opportunity rather than a hindrance to change.

A good example is here in the Illawarra, (Coastal New South Wales) where offshore wind has been very controversial in the last year. One of the lessons to be had is to not underestimate the community’s ability to understand what an energy transition means, and not to underestimate the degree of attachment people have to their local places.

The community here is highly knowledgeable about energy. The Illawarra has a workforce with a long history in heavy industry – the number of electricians per capita in the Illawarra must be as high as anywhere in Australia. And people have opinions – it’s not a passive region that knows nothing about the change that’s coming. The task is not purely to convince local people that this is a good thing, but to have a mature conversation with them about the pros and cons.

Who benefits in the energy transition?

There are all kinds of philosophical questions about who benefits, how those benefits are shared, what it means to turn our oceans into a space for energy generation. Some members of the community are asking for a proper conversation, because they don’t feel like they’ve been part of the story so far.

People react unpredictably to change that they see is imposed upon them. Let’s say it’s closing down a coal-fired power station in the Hunter Valley in New South Wales, or proposing a green hydrogen hub in South Australia – people don’t necessarily assess these as singular proposals that exist outside of everything else in their region or in their lives. People make sense of change in relation to their place, their community, their household, their family.

My work is about putting those people and their households first, and looking at it from their point of view. How does structural change look when we take into account the pressures of cost of living, on housing, on employment? People are grappling with these issues in their everyday lives.

There’s also a real risk in introducing changes that are presented to communities as if they have arrived from elsewhere, as a fait accompli. The direction of the flow of ideas and proposals, how they hit the ground, are a very important part of the process. If a proposal seems to arrive in their backyard from the top down – from a government or a corporation provider – you can get a community offside from the outset.

My work is about setting up different kinds of approaches that recognise that these communities have their own capacities and their own perspectives to offer. What we hope to do in the five years of the ARC Laureate program is develop an evidence base so that we can craft better models of how to manage this change. We’re looking at some of the implementations that have already occurred, tracing where those decarbonisation initiatives are hitting the ground, and looking at different kinds of community reactions – what sorts of processes work better than others in terms of building that relationship with community, as well as what happens when things end up in a more antagonistic situation.

Geography is the study of the relationship between humans and our environment. It has always occupied a slightly slippery position in universities and in public life, because we’re both a science and a social science, because we do this work of integrating perspectives from different areas of knowledge. In fact, we call ourselves all sorts of different things: we’re also environmental managers and coastal managers, policy officers and sustainability experts. It’s a discipline that connects, that fills the gaps. We often find solutions to problems by putting knowledge together from those different perspectives. It’s making these connections that can make a big difference.

Misinformation: how the printing press fuelled witch trials

October 11, 2024 Ellen Phiddian

The printing press – and a particular manual it printed – played a big role in early modern witch trials, according to a fascinating new study.

Between 1450 and 1750, some 90,000 people were put on trial for being witches across Europe.  About 45,000 of these people were executed.

Reasons for the fervour of this “witch craze” are murky. People had believed in witches for centuries, but brutal witch-hunts weren’t nearly as common until the 15th Century.

A study published in Theory and Society uses data on witch trials and witch-hunting publications to suggest that manuals may have been a big contributor.

In particular, they believe the Malleus maleficarum, which was first published in 1487, could explain a lot of the uptick – alongside trials in neighbouring cities.

“Cities weren’t making these decisions in isolation,” says lead author Dr Kerice Doten-Snitker, a postdoctoral fellow at the Santa Fe Institute, USA.

“They were watching what their neighbours were doing and learning from those examples. The combination of new ideas from books and the influence of nearby trials created the perfect conditions for these persecutions to spread.”

The researchers tracked the “ideational diffusion” – the spread of an idea, and behaviours linked to it – of witchcraft by looking at trial data and publication data from 553 cities in Central Europe.

They looked specifically for the publication of witch-hunting manuals, like the Malleus maleficarum.

This book contained a detailed explanation of “demonology” – the theory of witchcraft – as well as practical advice on finding and convicting witches.

“At the time of its appearance, there was only a shaky consensus among learned authorities on the crucial questions of who witches were, what they did, and why they had supernatural powers,” write the researchers in their paper.

“The willingness of [author Heinrich] Kramer to expound confidently on these questions is part of what made Malleus so influential.”

Each new edition of the Malleus maleficarum was linked to an increase in witch trials in the city where it was printed.

“The printing press did not cause the inception of the elaborated theory of witchcraft, but our results show that it fostered its spread,” write the researchers.

The team believes this ideational diffusion can be seen in many other areas.

“The process of adopting witch trials is not unlike how modern governments adopt new policies today,” says Doten-Snitker.

“It often starts with a change in ideas, which are reinforced through social networks. Over time, these ideas take root and change the behaviour of entire societies.”
