Not to be a Stickler, but …

Apparently, everyone wants to make a big deal out of this year's Pi Day because it is 3/14/15, which matches the first four digits in the decimal expansion of pi: 3.1415. The thing is that, pi expanded to five decimal places is 3.14159. Thus, taking the usual conventions for rounding into account, the correct four-digit approximation of pi is 3.1416. In other words we shall have just as much excuse to celebrate a year from today!
