2016 appears in π starting at the 7173rd decimal place:

You can confirm this with Mathematica or Wolfram Alpha:

Mod[ Floor[10^7177 pi] , 10000]

I found it using the following Python code:

>>> from sympy import pi >>> digits = str(pi.evalf(10000))[2:] >>> digits.find('2016') 7173

By the way, it’s also true that 2016 = 1 + 2 + 3 + … + 63.

The corresponding code in Matlab is:

p = sym(pi);

v=vpa(p,10000);

vc=char(v);

strfind(vc,’2016′)

2016 is almost certainly the last triangular year of my life, then. How should I celebrate it?

it would have been more interesting if 7173 was related to 2016 in some way.
