International Day of Mathematics or Pi Day observed globally
Every year on March 14, the International Day of Mathematics, also known as Pi Day, is observed to honour the mathematical constant Pi, which expresses the proportion of a circle’s circumference to its diameter.
The theme for Pi Day 2023 is “Mathematics for Everyone,”
The value for Pi is 3.14. Pi is a fundamental constant that is important for calculations, and scientists have studied and employed mathematics.
Pi Day will be recognised as International Mathematics Day in 2019 by the United Nations Educational, Scientific and Cultural Organization (UNESCO) at its 40th General Conference.
