In the United States, dates are indicated using the number of the month followed by the day of the month and the number of the year. March 14th, 2015 then becomes 3/14/15. Compare this with the first five digits of the ratio of the circumference to the diameter of a circle π = 3.1415. For extra fun, celebrate at 9:26:53 AM local time. The first ten digits of π are 3.141592653.
And remember — π are not squared, π are round, brownies are squared.
