Hmm. So there are two possible candidates for π-day.

2π-day is a funny way of referring to 𝜏-day.

@standupmaths An idea: someone should write a post in the style of the “𝜏 manifesto” but presenting all the reasons to prefer π over 𝜏. For example, present the fact that π is the ratio of the circumference of a circle to its diameter, where the 𝜏 manifesto talks about the ratio of the circumference of a circle to its radius.

@standupmaths I had heard of τ-day, now I hear of π-day. It’s twice as important…
