Everyday is a 2pi day.
2*pi*10/Phi^2= 23.9996 hours :-)

2pi shows up in many places in math and science:
* The formula C = 2pi r
* Converting between fractions of a revolution and radians
* Converting between frequency and angular frequency
* Fourier transforms
* Any physics involving waves
* The formula for the complex roots of unity
* The Gaussian distribution
* Stirling's approximation
Historical accident has given us a symbol for 3.14...,
but the number twice as large has a much better claim
to a place among the most important mathematical constants.
