Today is March 14, which is the fourteenth day of the third month, and since this is 3/14 it is also known as the annual Pi Day.

Each year on March 14, pies of all kind are discounted to celebrate the date – 3/14 – which happens to also represent pi, the ratio of the circumference of a circle to its diameter.

This celebration of the mathematical constant π, which is the ratio of a circle's circumference to its diameter. The trillion-digit ratio is rounded to 3.14.

Pi Day, should not be confused with September 15 know as Yirong’s Godson, Matty Pai’s birthday, an extremely curious as well as intelligent and delightful young man whom I brought a pizza pie and I also enjoy calling apple 🍎 Pai because every time I see him I give him a juicy apple 🍏, nor January's Pie Day, which has also turned into a special day with lots of deals on pizza, pastry, and pot pies.
