Pi Day and Pi Approximation Day are two
holidays held to celebrate the mathematical
constant π (pi). Pi Day is observed on March
14 (3/14 in American date format), due to π
being equal to roughly 3.14. Sometimes it is
celebrated on March 14 at 1:59 p.m. (commonly
known as Pi Minute). If π is truncated to
seven decimal places, it becomes 3.1415926,
making March 14 at 1:59:26 p.m., Pi Second
(or sometimes March 14, 1592 at 6:53:58
a.m.). Pi Approximation Day may be observed
on any of several dates, most often July 22
(22/7 (European date format) is a popular
approximation of π). March 14 also happens
to be Albert Einstein's birthday.
The first Pi Day celebration was held at the
San Francisco Exploratorium in 1988, with
staff and public marching around one of its
circular spaces, and then consuming fruit
pies; the museum has since added pizza pies
to its Pi Day menu.[1] The founder of Pi Day,
the "Prince of Pi", is Larry Shaw,[2] now
retired from the Exploratorium, but still
helping out with the celebrations. They have
also recently added the first Pi Day
celebrations in Second Life.
The Massachusetts Institute of Technology
often mails out its acceptance letters to be
delivered to prospective students on Pi
Day.[3]
Some also celebrate Pi Approximation Day in
addition to Pi Day, which can fall on any of
several dates:
* July 22: 22/7 in nearly all date
formats, an ancient approximation of pi
* November 10: The 314th day of the year
(November 9 in leap years)
* December 21, 1:13 p.m.: The 355th day
of the year (December 20 in leap years),
celebrated at 1:13 for the Chinese
approximation 355/113
On March 14, 2004, Daniel Tammet recited from
memory 22514 decimal digits of pi.[4] March
14, 1916 (3/14/16 in American date format) is
the closest approximation of pi in the last
century.
