All math-lovers have a special occasion today – a magical once-in-a-century Pi Day. It’s an international day which honors one of the most recognizable mathematical irrational symbols – “pi” or “π,” proving once again that math can be fun.

This Saturday, March 14,
2015 is 3/14/15 in the US date format which corresponds to the
first digits of a mathematical constant Pi: 3.1415. The best time
to enjoy all the ‘irritability’ of today’s day is to celebrate it
at 9:26 and 53 seconds, morning and evening as then the time
matches with all 10 digits of Pi: 3.141592653.

The holiday happens once in 100 years and the true fans of Pi
should really savor the moment as the next time it happens will
be in 2115. For the admirers of general theory of relativity it’s
also an occasion to celebrate Albert Einstein’s birthday, which
is also March 14.

“It’s the Pi Day of the century,” Michael Breen, public
awareness officer at the American Mathematical Society, told The
Boston Globe. “There’s a lot going on to celebrate.”

According to University of California Berkeley mathematician and
author Edward Frenkel, Pi is special as “it’s a portal into
this magical mysterious world of mathematics.”

One special feature of Pi, which is the constant used to
calculate the area of a circle, is that it is irrational so its
digits never end or repeat. Pi number was also put to use for the
construction of the ancient pyramid of Giza in Egypt.

“We cannot change it. It’s not subject to opinion or taste or
Frenkel said. “How many things like this in the
universe mean the same thing to everyone through time and

Some math enthusiasts want to pay tribute to one of the most
enigmatic numbers in the Queen of Science by eating pies.

“It’s humorous, it’s a lot of fun, and people obviously enjoy
eating pie,”
Tom Gaudette, principal academic evangelist at
MathWorks in Natick, MA. “For me, next year won’t be as

“It’s a real exciting moment for math enthusiasm,” said
Nathan Kaplan, a Yale University math professor, who called it a
time for people to “remember how much fun they found some of
the stuff in school.”

Pi Day celebrations are held or planned today all around the
globe. The events are arranged across the US, including New York,
San Francisco, Chicago and Los Angeles.
