Happy τ Day to all who celebrate!

Ein guter Tag, das τ zu preisen. #TauDay https://www.tauday.com/

@quietmarc @robinhouston Sorry I can only offer you two pies #TauDay

@BeefGriller Celebrate both #HalfTau day and #TauDay ! #HalfTauDay

Happy #PiDay to those who celebrate. But I prefer to wait for #TauDay myself.

Happy Tau Day, to those who use a weird date format. Unfortunately, there’s no pie.

#tauday

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

Einen kreisrunden #TauDay Ihnen allen!

Happy #TauDay all who celebrate...

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.

Happy Shameless Plug Day! ... With #TauDay (6.28) just a month away, I thought I'd mention (again) my tau-and-pi t-shirts. (Remember: There's room enough on the number line for both values, so let's stop with the belligerence!) Available in my InspiredByMath shop on Etsy. #ShamelessPlug

(Kangleroo and Law-of-Cosines designs are also available, with more on the way.)

Thanks for your support!

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….

@scerruti But you have to wait ANOTHER 3 months and 14 days for #tauday

🚨🚨 URGENT 🚨🚨
Humanity needs a dish which is delicious and easy enough to prepare, but not that simple to be an everyday food. And it must be named a Tau. Or phonetically close to Tau.

#PiDay #TauDay

Ah, wieder Halbzeit bis zum #TauDay. #PiDay

Happy #TauDay !

BTW: "matrico" http://wiki.call-cc.org/eggref/5/matrico only provides Tau.

Happy Tau Day for those of you using MM/DD calendar formats!

Happy Tau (τ) Day to all of you who believe π is "wrong"!

Unlike π day, where you are limited to eating pie, τ day may be celebrated by eating all the round foods.

Here's some generative art involving τ - both with the main circle and the sin/cos functions used in the pattern.

Given the axioms of IZF set theory, define real numbers as Dedekind cuts, the complex exponential as the limit of an infinite series, and sine and cosine in terms of the complex exponential. Define τ to be the smallest positive real whose cosine is one. Define π to be the smallest positive real whose sine is zero. Theorem: τ = 2π. Formalized in metamath at https://us.metamath.org/ileuni/taupi.html . Happy #TauDay !
