Pi Approximation Day is celebrated on July 22 because the date reflects the fraction 22/7, a common approximation of pi (π). This day is significant as it raises awareness about pi's importance in various scientific and mathematical fields, tracing back to Archimedes' calculations. Notable quotes about pi highlight its representation of infinite possibilities within mathematics.

1. Pi Approximation Day
22 JUL, 2023

3. What is Pi Approximation Day celebrated?
Pi Approximation Day is observed on July
22 because the day of the month (22) divided
by 7 (7th month of the year) equals the
approximation of Pi (3.14)

4. Why is July 22 Pi Approximation Day?
• Pi Approximation Day is observed on July 22 (22/7
in the day/month date format), since the fraction
22⁄7 is a common approximation of π, which is
accurate to two decimal places and dates from
Archimedes

5. Who created pi?
• Archimedes of Syracuse
• The Egyptians calculated the area of a circle by a formula
that gave the approximate value of 3.1605 for π. The first
calculation of π was done by Archimedes of
Syracuse (287–212 BC), one of the greatest
mathematicians of the ancient world.

6. Pi Approximation Day Significance
• Pi Approximation Day is significant because it raises
awareness about pi, a mathematical constant that is central
to many fields of science and engineering.
• Pi Approximation Day celebrates pi and its importance in
mathematics and science.
• It is approximately equal to 3.14159

9. Pi Approximation Day Quotes
•"Pi is not just a number, it's a symbol of the infinite
possibilities of mathematics." - Marcus du Sautoy
•"Pi is the intersection between the infinite and the
finite, the point where mathematics and reality
meet." - Steven Strogatz
