Pi Day

Pi Day

Pi Day is observed every year on March 14, and it is a day to commemorate the mathematical constant of Pi. It is only a fun observance, and as such, businesses and schools are open as usual.

Why is Pi Day celebrated on March 14?
In the American month/day way of writing a date, Pi Day happens on 3/14. 3.14 are the first three digits of Pi. If you love maths, you can have your Pi Day celebrations at exactly 1:59 a.m or p.m, so that they happen at exactly 3.14159.

Some math lovers also celebrate Pi Approximation Day on July 22, as 22/7 is the fraction that represents Pi.
