What is Pi Day?

Pi Day is an annual celebration of the mathematical constant pi (π). Here’s what makes it special:

  • Date: Pi Day is celebrated universally on the 14th of March (14/3) because the first three digits of pi are 3.14.
  • Why Pi? Pi is essential in any calculations involving circles. The concept of Pi represents the ratio of a circle’s circumference (the distance around) to its diameter (the distance across).


How is it celebrated?

  • Maths-themed events, games, and puzzles
  • Pi recitation contests (where people try to memorise as many digits of pi as possible)
  • Eating pie (a fun play on the similar-sounding words “pie” and “pi”)

Importance of pi

Pi ((π) can be easily counted as geometry’s one of the cornerstones and the value of it is 3.14159. Here are the importance of Pi:

  • Pi helps us understand circles, that is it tells us how big around a circle is compared to how wide it is. 
  • Scientists and mathematicians use this concept to calculate the orbits of planets in space stations.
  • Whether it’s bridges, buildings, or designing parts for machines, Pi helps architects to build them properly.

Use of Pi in Real Life.

Pi appears in our daily lives more often than we realise. Here are a number of interesting ways that it is used:

  • Baking Pies: The bakers use this core mathematical concept to determine the amount of filling they need to make delicious round pies.
  • Sports: Pi can be an easy solution if you ever wondered how to create the perfect circle track where athletes can run on.
  • Building Something: Architects and engineers use pi in the design of buildings, bridges and wheels ensuring that everything works out properly.
  • Space Travelling: Space science is hugely dependent on Pi. The space scientists use this concept to calculate the path for satellites and spaceships, thus maximizing space travel.
  • Everyday Devices: There are various gadgets which we use in our daily lives, including your phone, computer or even your car have been designed with the help this concept.
