Pi Day

Every number is interesting and has its own importance in the World of Mathematics. But some numbers are more amazing than others. One such amazing number is Pi ( ℼ ), which has been a point of attraction for Mathematicians across the World since its inception.


Does ℼ really need any introduction? Certainly not! Everyone is familiar with it since childhood.

The fantabulous number ℼ is the ratio of the circumference of a circle to its diameter.

The symbol ℼ (ℼ is a constant) was introduced by William Jones in 1706 and later made popular by Leonhard Euler...

Pi Approximation Day

In countries where the day/month (dd/mm) format is followed, Mathematicians honor ℼ on Pi Approximation Day. The date of Pi Approximation Day is July 22, which when written in day/month format, is the well-adopted approximation 22/7 of ℼ.


Looking at ℼ with the first few digits 3.1415926, the exact time of celebrating ℼ Day comes out to be "March 14 at 1:59:26 pm."

India celebrates December 22, the birth anniversary of the legendary Mathematician Srinivasa Ramanujan, as National Day of Mathematics...
