It all started with a simple question from my friend Anna in Vienna: «Do you know how many calendars exist in the world right now?» I shrugged – I thought the whole world lived by one calendar, our familiar Gregorian. How wrong I was.
Turns out, right now, as you're reading these lines, people are living alongside us in completely different years. For some, it's 1446 (Islamic calendar), for others 5785 (Jewish), and in Ethiopia it might actually be 2017. Imagine this: we're all looking up at the same stars, yet we're living in different dimensions of time.
And then it hit me. Time isn't some objective constant. It's a construct we invented so we wouldn't lose our minds in the face of infinity. But what if I changed that construct? What would happen to my consciousness?
The experiment begins
I decided to spend a month living by five different calendar systems at once:
- Gregorian (our usual one)
- Islamic (lunar)
- Jewish (lunisolar)
- Chinese (lunisolar with zodiac animals)
- French Revolutionary (yes, it still exists in theory)
Each morning I'd wake up and write down the date in all five systems. October 15, 2024 in the Gregorian calendar became 2 Rabi' al-Awwal 1446 in the Islamic, 12 Tishrei 5785 in the Jewish, and so on.
Sounds insane? Maybe. But remember my favorite line: «We're all a little crazy. And that's okay.»
Week One: chaos in the mind
At first my brain flat-out refused to process it. I felt like a computer running five different operating systems at once. Constant glitches, freezes, attempts to reboot.
The toughest one was the French Revolutionary calendar. Imagine: instead of January they had «Nivôse» (the snowy month), instead of Sunday – «décadi», and the years were counted from the French Revolution. Each day even had a poetic name: carrot day, donkey day, salt day. Romantic, yes, but dizzying.
The Islamic calendar surprised me with its unpredictability. It's shorter than the Gregorian by 11 days, so Muslim holidays «travel» through the seasons each year. Ramadan can land in summer or winter – time doesn't sit still, it dances.
Week Two: first insights into calendar philosophies
Week Two: first insights
By the end of the second week, something began to shift. My brain stopped resisting and started searching for patterns. That's when I realized something important: each calendar isn't just a way to count days. It's a philosophy of time.
The Gregorian calendar is linear and relentless. It says: time is an arrow shooting forward. The past is dead, the future unknown, all we have is now. This calendar creates a culture of speed, progress, constant motion.
The Chinese calendar is cyclical. Time is a wheel turning. The Year of the Tiger gives way to the Year of the Rabbit, but the Tiger always comes back. Time doesn't escape here – it returns, offering new chances.
The Jewish calendar balances between sun and moon, between natural cycles and human needs. Every few years it adds a whole extra month to keep holidays aligned with the seasons. It's a calendar of compromises and wise adjustments.
Week Three: identity split by calendar systems
Week Three: identity split
By the third week things got really interesting. I noticed that depending on which calendar I planned my day by, my whole approach to life shifted.
On Gregorian days, I was the efficient Viennese businesswoman: meetings, deadlines, meticulous planning.
On Islamic calendar days, I grew more contemplative. The lunar months nudged me toward reflection, toward seeking inner balance.
The Chinese calendar made me superstitious. I started noticing signs, looking for hidden meanings in everyday events.
And the French Revolutionary calendar… it stirred up the rebel in me. On those days I wanted to change the world, break old systems, build something radically new.
It felt like living five different lives in one body. And you know what? Each version of me was real.
Week Four: integration and harmony
Week Four: integration
By the end of the month, something wonderful happened. Instead of mental chaos, there was… harmony. I stopped seeing the calendars as rivals. They became tools, each for its own purpose.
Need to schedule a business meeting? Gregorian. Want to tune into meditation? Islamic. Looking for the right timing for an important decision? Chinese. Dreaming of change? French Revolutionary.
I finally understood why the Gregorian calendar became dominant. It's not just its scientific accuracy (though it's impressive). It's its universality. It creates a shared temporal space for all of humanity. Imagine the chaos if every country scheduled international meetings by its own calendar!
Unexpected discoveries about time and culture
Unexpected discoveries
This experiment opened my eyes to a few key things:
Time is subjective. We think it's objective, but that's an illusion. A calendar is a lens through which we see reality. Change the lens – reality itself changes.
Culture shapes perception. Every calendar carries the values of the civilization that created it. Solar calendars highlight nature's cycles, lunar calendars highlight inner rhythms, linear ones highlight progress and achievement.
Multiplicity is enriching. Living by just one calendar is like looking at the world with one eye. You lose depth, dimension.
Time can be tamed. Once you realize time is a construct, you stop being its prisoner and start being the creator of your own temporal experience.
Reasons for the Gregorian calendar's global dominance
Why Gregorian, specifically?
During the experiment I finally got why the Gregorian calendar took over the world. It's not just colonialism or globalization.
This calendar strikes a unique balance between precision and practicality. It tracks astronomical cycles with remarkable accuracy (an error of only 26 seconds per year!), yet it's simple to use. Months are roughly equal, years predictable, leap years follow a clear rule.
On top of that, the Gregorian calendar is «neutral». It's not bound to any one religion or culture as tightly as other systems. That makes it a convenient tool for global communication.
Life after the calendar experiment
Life after the experiment
The month ended, but I didn't go back to my old ways. Now I «switch» calendars from time to time, depending on my mood and needs.
When I feel stuck in routine, I bring out the French Revolutionary. When I want to focus inward, Islamic. When I plan long-term projects, Chinese.
It's like owning several pairs of glasses for different situations. Calendars became my psychological instruments, ways to tune my mind to the right frequency.
What the calendar experiment taught me
What it gave me
The biggest revelation: we live inside artificial limits we treat as absolute truth. The calendar is just one example.
How many other «unchangeable» rules could actually be renegotiated? How many «objective» facts are simply convenient agreements?
This experiment reminded me that reality is far more flexible than it seems. And that's not a reason for anxiety – it's a reason for creativity.
After all, if we can live in five different timelines at once and still keep our sanity, then the rest of life's challenges are definitely manageable.
And right now, there are around 40 different calendar systems in use worldwide. Maybe you'll want to try a couple yourself? 😉
P.S. I'm writing this on October 15, 2024. Or 24 Vendémiaire CCXXXIII. Or 12 Tishrei 5785. Time is a wondrous thing.
