Top left text says "June 28th (06-28) is Tau Day! celebrating the one true circle constant". Top right text has the Greek letter tau, an equals sign, and "6.2831853...". Bottom centre is a diagram of a circle with radius 1, with dashed circular arrows showing that pi only corresponds with half a turn, while tau is a full turn, or 2 times pi. Bottom left text says "why only half a turn, pi?". Bottom right text says "tau is a full turn. tau gets it!".
Happy Tau Day to all who celebrate! What better day to mark a full turn around the Sun than the day for a number that represents a full turn around a circle? 💜 🖥️😺 #TauDay

Happy Tau Day Numberfans (6/28)! Tau is a constant number that's two lots of pi, and it’s the ratio of the circumference to the radius.
Listen to this song from our biggest number-fan, Arifmetix, as his number "Tau" sings a song!

A unit circle tesselated by a hexagon, demonstrating that all segments are of unit length, as are the radii that connect their vertices to the center. Taking the limit of the sum of the lengths of tesselated segments, as the number of segments goes to infinity, you will get 𝜏!
Happy #tauday to those who celebrate!
State of the 𝜏: www.tauday.com/state-of-the...
The 𝜏 manifesto: www.tauday.com/tau-manifesto
I particularly liked this simple visual proof that 𝜏 is just a bit over 6, based on the limit of tesselating a circle.

A cartoon illustration showing the Greek letter tau (τ) with a smiling face on the left. On the right, there are two smiling cartoon pies stacked vertically. An equal sign is between them, indicating that tau equals two pies. The background is dark blue.
Happy Tau Day!
We celebrate both Pi Day and Tau Day at our house. Tau (≈6.28) is 2π, and some say it is the better circle constant. Either way, it is a great chance to talk angles, radians, and geometry with kids. Preferably over something round and tasty. #TauDay

A graphic showing the mathematical sign for Tau followed by an equal sign followed by an illustration of two pies.
It's also #TauDay today, a celebration of the circle constant. It’s numerically equal to 2*Pi, so some think it’s better than Pi. Are you #TeamTau or #TeamPi?
Maybe the Tau Manifesto will help you decide

While I'm at it ... Since division is better as an operation than a motivation, here's a quick musical PSA advocating against pi-vs-tau tribalism. (Apologies to Billy Preston.) #PiDay #TauDay

In drei Tagen, am 28. Juni, ist schon wieder #TauDay (Tau = 2*Pi). Bereiten Sie sich entsprechend vor und kaufen und/oder backen Sie rechtzeitig zwei Kuchen. So will es das Gesetz.
Tragiff.

Pi and Tau COEXIST design, showing pi as the unit circle's area and tau as its circumference.
Pi and Tau design, showing the circle's area as pi times the *second* power of the radius and its circumference as tau times the *first* power of the radius, noting the coincidence that the symbol for pi has two "stems" and that of tau has just one.
Happy Shameless Plug Day! ... With #TauDay (6.28) just a month away, I thought I'd mention my tau-and-pi t-shirts. (Remember: There's room on the number line for both values, so let's stop with the belligerence!) See my InspiredByMath shop on Etsy.

Thanks for your support!

COEXIST pi and tau t-shirt design
Pi and Tau mnemonic t-shirt design
Happy Shameless Plug Day! ... I'm adding t-shirts to my Etsy shop. #ShamelessPlug
To get a jump on #TauDay (6.28), I'm starting with two Tau (and Pi) designs: COEXIST and a mnemonic. I think I'll add Kangleroo next.

I have failed my civic duty: I forgot to buy pies for #piday. What am I to do? Buy some Monday and mess up #stpatricksday or wait all the way until June to hit #tauday?

We prefer Tau Day in this house, but this is an amusing diversion….
