What is Pi Day?

Every year, Pi Day has been celebrated in several ways, including throwing pies, eating pies, and discussing the importance of the π. With pi and pie being homophones in English and the circular shape of pies, people tend to celebrate Pi day by making pies. In addition to that, a lot of schools also hold competitions like which student recalls the highest decimal number of Pi.

Princeton, New Jersey, hosts multiple events every year to celebrate both Pi Day and Albert Einstein's birthday. Einstein used to live in Princeton and worked at the Institute for Advanced Study. Apart from pie-eating competitions to recitation contests, they also organise an Einstein look-alike contest. The celebration of Pi day has already begun around the world.
