International Mathematics Day Observed Annually on March 14 Since 2020

International Mathematics Day is observed annually on March 14, a date chosen to coincide with Pi Day, which celebrates the mathematical constant π (3.14). Officially proclaimed by UNESCO in November 2019, the day was first celebrated in 2020 with the theme "Mathematics is Everywhere." Supported by the International Mathematical Union, the observance aims to highlight mathematics' role in education, research, and solving real-world problems, with schools and institutions worldwide organizing related events.
