National Pi Day is held each year on March 14. It honors 3.14 the ratio of the circumference of a circle. You can also get deals on food too.

If you were to use that distance as a radius and calculate the circumference, using more digits of pi would only add slightly over 1 centimeter (0.4 inches) to your value.

If you use this simpler number, you get a pretty good estimation of a circle’s circumference. DeepSeek did something similar — but on a much larger scale — in training its A.I. technology.

SUMMERS: "Will The Circle Be Unbroken" is also sung at every Country Music Hall of Fame induction ceremony. But this song's significance goes beyond country music.
