What is Pi Day?
I’m a math educator and I’ve celebrated Pi Day for many, many years. It isn’t the most widely celebrated holiday, so let me explain what it means. Today is March 13, which can also be noted as 3/14. The mathematical notation Pi is rounded to 3.14, so math classrooms around the world celebrate Pi Day today.
