Since a year is a cycle, it should be divisible by π, and its radius calculated.

So, if we correlate 365 days to 360 degrees, 365/2/π = 58.09 days, which puts the radius at about February 12. Double that to find the diameter of the year: April 17.

Care to represent that graphically? Jan 1 and April 17 should be opposite points on a circle. Erm.
