Beyond the Pope's Timeline: How a Papal Decree Colonized Your Calendar
By Moataz Joudi
Here's a question nobody asks out loud: Why does a Pope get to decide what year it is?
Not a scientist. Not a democratically elected body. Not the combined wisdom of the Mesopotamians, the Egyptians, the Maya, or the countless civilizations that spent millennia watching the stars before Europe had running water. A single Catholic monarch—Pope Gregory XIII; signed a papal bull in 1582, and somehow, five centuries later, eight billion people are living inside his calendar.
That's not tradition. That's a colonial inheritance we forgot to question.
1. This Calendar Has a Name, and That Name Is a Problem
We call it the Gregorian calendar because that's exactly what it is: Pope Gregory XIII's calendar.
Before Gregory, Europe used the Julian calendar, Julius Caesar's calendar, which he imposed on his empire in 46 BC. One emperor's calendar replaced by one pope's calendar. That's the full lineage of the system currently organizing your life.
The AD/BC epoch at its core goes back even further. In 525 CE, a Scythian monk named Dionysius Exiguus invented the "Anno Domini" counting system: Year of the Lord explicitly to replace numbering from the reign of Roman Emperor Diocletian, a persecutor of Christians. His goal was theological. His math was wrong (he miscalculated the birth of Jesus). And his system became the backbone of global timekeeping for 1,500 years.
The calendar isn't neutral infrastructure. It is, from its very origin, a monument to one religion's claim over history.
2. It Wasn't Adopted. It Was Imposed.
When Spanish conquistadors arrived in the Americas, they didn't find people living in a timeless void. The Aztec civilization used two interlocking calendars of staggering mathematical precision. The Maya had calculated the length of the solar year to within 0.0002 days. Across the Pacific, cultures from China to India to Persia had been tracking astronomical cycles for thousands of years with systems the Gregorian calendar never bothered to acknowledge.
Those calendars weren't replaced because they were inferior. They were replaced because colonialism doesn't ask for input.
The Gregorian calendar spread across Africa, the Americas, Asia, and the Pacific through the same process as forced conversion, land seizure, and the destruction of indigenous languages: by making the colonized world illegible except through European frameworks. Once you control how a people measures time, you control how they understand their own history. You decide what counts as civilization and what counts as "prehistory."
This is not metaphor. It is mechanism.
3. The Invisible Erasure
Here's what the current system actually does to history, in plain terms:
The Sumerian city of Uruk, arguably the first true city on Earth, was founded around 5,000 years after the first farmers (that is, about -7,000 BCE in the old system).
Under our current calendar, that date is rendered as a negative number, a countdown toward zero, as if civilization were falling toward something rather than building toward it. The entire era reads like a prelude to a story that only really begins with Rome, and then again with Christianity. Like everything before didn't count until Jesus.
The implication is structural, not accidental: everything before year 1 AD is "Before Christ." Literally labeled by its distance from a single religious event.
The Egyptian Old Kingdom. The Indus Valley cities of Mohenjo-Daro and Harappa. The megalithic monuments of Göbekli Tepe, built 7,000 years before Stonehenge. All of it filed under "negative years." All of it framed as before history began.
The Gregorian calendar doesn't just ignore these civilizations. It tells us, structurally, that they were the warm-up act.
4. The Fix Is Not Complicated
None of this requires throwing out the Gregorian calendar's practical usefulness. It works fine for scheduling meetings and knowing when the garbage gets collected.
What it requires is a better epoch! A better starting point for the count.
The Human Era (HE) calendar, proposed by scientist Cesare Emiliani in 1993, offers exactly this. It begins approximately 12,000 years ago, at the dawn of the Holocene geological epoch and the Neolithic Revolution: the moment our ancestors domesticated crops, built the first settlements, and began the long project we now call civilization.
The conversion is simple: add 10,000 years. The year 2026 CE becomes 12026 HE. Uruk's founding becomes year 5000 HE: a positive, forward-moving number on a continuous timeline.
No religion. No empire. No papal bulls***. Just humanity, starting from the beginning. Year 1 is the first farmers, year 12026 the age of AI.
Doesn't it make a lot more sense to say it took us 12000 years from farming to reaching space?
The Point Is Not Inconvenience
The Gregorian calendar's defenders often say: But everyone uses it. It works. Why make things complicated? And what's the point of changing it now?
Because "it works" is what people said about every unjust system until enough people stopped accepting it.
The calendar isn't just a scheduling tool. It's a story about who matters in history and who gets treated as a footnote. Every time we write "-3000 BC," we're narrating the past through a framework that was built, explicitly, to center one civilization, one religion, and one set of empires.
The Human Era calendar doesn't erase the last 2026 years. It restores the 10,000 that came before them.
Hanging a HOLOCENE calendar on your wall is a small act. But it's a refusal, a quiet, daily refusal to let a 16th-century pope keep organizing your sense of human history.
It's 12026 HE. Good luck unseeing this :)
