International Day of Mathematics and Pi Day 2023: History, wishes, status, messages, quiz, activities & more

Every year on March 14th, the International Day of Mathematics (IDM) is observed to acknowledge the value and allure of mathematics in our daily lives. The day was picked to commemorate the great mathematician Albert Einstein's birthday.

The International Mathematical Union (IMU), in cooperation with UNESCO and other organisations, organised the IDM for the first time in 2020. The first IDM's theme, "Mathematics is Everywhere," emphasised the subject's pervasiveness in industries like science, engineering, finance, and technology.

The IDM strives to foster research and appreciation of mathematics' many applications and contributions to society, as well as to raise awareness and comprehension of mathematics among individuals of all ages and backgrounds. It also aims to encourage and help the next generation of scientists and mathematicians.

The celebration of the IDM comprises numerous activities and events, such as lectures, workshops, competitions, and exhibitions, that reflect the beauty and importance of mathematics. To support instructors and students in having fun and actively participating in mathematics, the IMU also distributes tools and resources.

Ultimately, the IDM offers a chance to acknowledge the significant impact mathematics has had on the development of our world and to inspire more individuals to pursue and value this vital and intriguing topic.

What is Pi Day?

Every year on March 14 (3/14) there is a celebration called Pi Day to honour the mathematical constant (pi). Pi is roughly equal to 3.14159 and is the ratio of a circle's circumference to its diameter.

Pi Day has grown in popularity among math lovers and educators all around the world since it was first observed by physicist Larry Shaw at the Exploratorium in San Francisco in 1988.
