Pi Greco Day 2026

The Pi Greco Day 2026 event is promoted by the Ministry of Education and Merit with the scientific contribution of the Department of Molecular Biotechnology and Health Sciences of the University of Turin, to celebrate Pi Day with the aim of bringing all young people closer to Mathematics and to communicate the commitment of the Ministry and schools to the learning of Mathematics and scientific disciplines.

The Pi (π) is a fundamental mathematical constant, defined as the ratio between a circle’s circumference and its diameter. Its approximate value is 3.14159, but it is an irrational number, meaning it has infinitely many decimal digits with no repeating pattern. Used in numerous areas of mathematics, physics, and engineering, π is essential for calculating the areas and volumes of circular and spherical shapes. Every year, on March 14th, Pi Day is celebrated: a day dedicated to this extraordinary constant.

The institutional Pi Day event will take place in person on 16th March 2026 in Rome, at the Ministry of Education and Merit, while the national online event will be held on the Pi Greco Day platform from 14th to 16th March 2026, allowing the participation of students from schools of all levels throughout Italy and from Italian schools abroad.

Now fully established at national level, the initiative represents one of the main actions aimed at promoting mathematical culture and STEM disciplines within the Italian school system.
