2π = τ, which means that tomorrow is Tau Day! (Remember 3/14 is Pi Day, since Pi ≈ 3.14). Since tomorrow is 6/28 (or 2(3.14)) tomorrow, June 28 is Tau Day! How will you celebrate? Might I suggest you celebrate with 2 pies?

For more Tau Day fun check out my Pi Day activities . . . just do them twice!
