What is Pi Approximation Day celebrated?
Pi or pie, whether you’re a baker or a math whiz, today is your day — Pi Approximation Day on July 22 honors the concept of pi, which is denoted by the Greek letter pi and approximates to 3.14, in the most mathematically-pleasing way.
What is the difference between Pi Day and Pi Approximation Day?
Pi Day is most frequently observed on March 14, but related celebrations have been held on alternative dates. Pi Approximation Day is observed on July 22 (22/7 in the day/month format), since the fraction 22⁄7 is a common approximation of π, which is accurate to two decimal places and dates from Archimedes.
