Pi Day, celebrated annually on March 14 (3/14), is a worldwide celebration of the mathematical constant pi (π). Pi is the ratio of a circle’s circumference to its diameter, and it is approximately equal to 3.14159.
The date of March 14th was chosen for Pi Day because the first three digits of pi are 3, 1, and 4. In many countries, including the United States, this date is written as 3/14, which corresponds to the first three digits of pi.
What are some fun facts about pi?
Pi is an irrational number, which means that it cannot be expressed as a fraction of two integers.
Pi is a transcendental number, which means that it is not the root of any polynomial equation with rational coefficients.
The first recorded calculation of pi was made by the Chinese mathematician Liu Hui in the 3rd century AD.
The Greek mathematician Archimedes calculated pi in the 2nd century BC.
The value of pi has been calculated to trillions of digits.

History of Pi Day
The first Pi Day was celebrated in 1988 by Larry Shaw, a physicist at the Exploratorium in San Francisco. Shaw chose March 14th for the celebration because it is the date of Albert Einstein’s birthday. Einstein was a theoretical physicist who developed the theory of relativity. He is also known for his mass–energy equivalence formula, E = mc2.
Pi Day has since become a popular event celebrated by mathematicians, scientists, and engineers around the world. People celebrate Pi Day in many ways, including eating pie, reciting pi digits, and participating in pi-themed activities.
