World Logic Day

World Logic Day is an international day proclaimed by UNESCO in association with the International Council for Philosophy and Human Sciences (CIPSH) in November 2019 to be celebrated on 14 January every year. It was first celebrated on 14 January 2019, before the UNESCO declaration. World Logic Day intends to bring the intellectual history, conceptual significance and practical implications of logic to the attention of interdisciplinary science communities and the broader public.

The date chosen to celebrate World Logic Day, 14 January, corresponds to the date of death of Kurt Gödel and the date of birth of Alfred Tarski, two of the most prominent logicians of the twentieth century.
