This year's Pi Day is even more special than you know

Today is the most magical day of the year: Pi Day.
 It's also the most magical year of the century: Pi Year.
 That is, today's date is 3/14/15 (at least in the US and a few other countries that write dates the same way), which matches up nicely with the first five digits of pi, the ratio of every circle's circumference to its diameter: 3.1415.

  But it doesn't stop there.
