Celebrate Pi Approximation Day (22 July) by Learning Its Interesting Significance

Pi Approximation Day is celebrated every year on 22 July and there’s a very special reason behind the same. The value of Pi is 3.14, that is a result of the fraction 22/7 – the date! Also known as Casual Pi Day, the day glorifies the mathematical constant pi (π), that denotes the relationship between a circle's circumference and its diameter.

However, some people also celebrate the Pi Approximation Day on 14 March, as the simplified value of the fraction is 3.14, which turns to be 14/3 in the date format. The enthusiasts have debated on the irrationality of celebrating on the 14 of March, as the decimal approximation value never ends nor repeats! See for yourself: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 and it goes on.

Interestingly, there are many reasons for the day to be more special, as Pi is somehow present in every aspect of our lives. For example, scientists at NASA keep the space station in operation with 15 or 16 digits of Pi and Pi computation can be used to test computer precision. The strive to discover more values of Pi for practical application and use on Earth has been driving many mathematicians, physicists and academics across the world. Clearly, the day definitely deserves to be celebrated and rejoiced!

We think you should enjoy the day by eating pie or watching the movie ‘Life of the Pi,’ whereas science enthusiasts can do a contest of reciting Pi values. Did you know, in 2006, Akira Haraguchi of Japan recited 1,00,000 digits of Pi from memory in 16 ½ hours, stopping only for five minutes every hour?
