World Brain Day is celebrated globally on July 22nd every year. The day promotes education, research, and support for individuals affected by brain-related conditions.
On July 22, 1957, the World Federation of Neurology (WFN) was established.

This proposal was presented during the World Congress of Neurology (WCN) Council of Delegates meeting on September 22, 2013, and it received a warm and enthusiastic response from the delegates. Following this positive reception, the Board of Trustees approved the concept in their meeting held in February 2014, making it an annual event to be celebrated on the same date each year.
The theme for World Brain Day 2023 was 'Brain Health and Disability: Leave No One Behind'.

Archimedes tried to show that the value π is between 3 1/7 and 3 10/71.
