March 14, 2026 : Happy Pi Day!
Another year, another Pi Day. It’s time to enjoy various math memes, pie photos, and general nerdiness that pops up online. It is one of those oddly specific celebrations that somehow stuck around.
One obscure Pi Day tidbit I recently learned: the holiday itself was first celebrated in 1988 at the Exploratorium in San Francisco, where staff marched around a circular space and then ate fruit pies. Hard to argue with that tradition.
While the mathematical side of Pi can get pretty deep (and infinitely long), the day itself is a nice reminder that math can be fun… and occasionally delicious.

July 22, 2025 : Happy Pi Approximation Day!
Even though it may be getting a bit too hot and humid these days, we can all at least take some solace in the fact that it’s Pi Approximation Day! Little tidbit: it is also Casual Pi Day, which seems… about right?
I recently learned this glorious day is sandwiched between Junk Food Day (7/21) and Vanilla Ice Cream Day (7/23); which to be honest with you, both seem equal parts fake and unnecessary. Whereas Pi Approximation Day is vital. After all, any excuse to celebrate Pi is a good one.

Does today’s uncertainty have you in a funk? Cheer up! It’s everyone’s favorite nerdy Holiday… Pi Day. And even better, a Friday-Pi Day!
Did you know that Pi has been calculated to over 105 trillion digits; but despite this accuracy, NASA only uses 16 digits? That’s sounds irrational to me… I’ll show my self out.

July 22, 2024 : Happy Pi Approximation Day!
Is it July already? Rather than dwell on summer being half over, let’s focus on the greatness of Pi Approximation Day! After all, we’re only a third of the way through summer if you base it off the solstice/astronomical definition versus the meteorological.
Call it whatever you want – ballparking it, taking a shortcut, or simply half-assing things – but I’ll use it as an excuse to celebrate Pi.

Who’s ready to relate a circle’s circumference to its diameter… at least more so than normal? That’s right, it’s Pi Day, which means it’s time to geek out about the world’s most needed irrational mathematical constant.
Usually at this point in the post I relay some interesting fact. Sadly, I don’t have much to offer this year. How about this: did you know that the one millionth digit after the decimal point is a “1”?
Sorry, but I told you I didn’t have much. How about Albert Einstein was born on Pi Day? That’s pretty interesting; and I’m pretty sure I’ve never mentioned it on here before, which I find odd (and disappointing).

With summer well underway, it’s about time we have some fun (that’s highbrow there)… and there’s no better way than by celebrating Pi Approximation Day!
I’d like to think with the advent of calculators, people don’t have to approximate Pi; but here we are. While I wouldn’t recommend estimating it – particularly with such inaccuracy – I am all for giving Pi another day on the calendar to celebrate it.

Spring is upon us. Not only does that mean some potential Illinois March Madness action (apparently… but to be honest, I haven’t watched a single game this season), but it also means the return of C2E2. Most importantly, it’s that time of year where we get to enjoy the awesomeness that is Pi Day!
Fun fact: Pi didn’t get its name until the early 1700’s. Before then, people just used the definition when talking about it (“the quantity which, when the diameter is multiplied by it, yields the circumference”). Pi is definitely more succinct. Happy Pi Day!

July 22, 2022 : Happy Pi Approximation Day!
The Silver Medal to my favorite day is here… Pi Approximation Day! The reminder that Pi is so great, it gets two separate celebrations each year.
If you want to learn something fun (and crazy), read about the Indiana Pi Bill. It’s a bizarre story of someone trying to pass a bill in the late 1800’s claiming he found a way to “Square the Circle” – something that cannot be done because of Pi’s inherent nature (i.e. it’s ‘transcendental’). Still, it didn’t stop someone from confusing others, wasting people’s time, and ultimately making a fool of oneself… and the state of Indiana. Good stuff.

Well if it isn’t that glorious time of year… where we get to celebrate the incredible mathematical symbol that is Pi. Plus, we also get to enjoy Illinois back in the Big Dance (I haven’t watched a game of theirs this year, but that’s on me). Rather than show a pic, I figured I would re-post a video I made a few years back in Cinema 4D – since I’ve been meaning to get more into C4D:
Unlike Pi, it’s not perfect; but I still like it! While you enjoy the day, feel free to reflect on where we’d be without this constant. If that doesn’t make you appreciate life, then I don’t know what will. Happy Pi Day!

July 22, 2021 : Happy Pi Approximation Day!
Just because it ain’t the real thing, doesn’t mean it isn’t real! Today is the day we celebrate the knock-off to end all knock-off’s… Pi Approximation Day.
Please don’t construe my love for this glorious day as an endorsement of half-assing things. The rest of my actions throughout life should more than attest to that. But in all seriousness, approximate Pi at your own peril – it can have disastrous results.
