What is Pi?

Pi (π) is a special number used in mathematics to understand circles. It represents the ratio of a circle’s circumference (distance around) to its diameter (distance across). No matter how big or small a circle is, this ratio always stays the same — about 3.14. Pi is an infinite number, which means its digits go on forever and never repeat!

Why is Pi Important in Real Life?

• Architecture & construction – designing buildings, bridges, and domes
• Science & space – calculating orbits and waves
• Technology – used in programming and simulations
• Everyday life – measuring round objects like pizzas or wheels

Why Do We Celebrate Pi Day on March 14?

Pi Day is celebrated on March 14 (3/14) because it matches the first three digits of pi (3.14).

• First celebrated in 1988 by physicist Larry Shaw
• Recognized officially in the U.S. in 2009
• Declared the International Day of Mathematics by UNESCO in 2019
• It’s also the birthday of Albert Einstein!
