World Logic Day was celebrated for the first time on January 14, 2019. The date chosen, 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. On 26 November 2019, UNESCO proclaimed 14 January to be World Logic Day and included it in its list of International Days. This year, World Logic Day will be celebrated for the fourth time. The event is very popular worldwide. Last year there were 82 scientific events in 40 countries and this year 50 countries have already registered to participate.

For a second time, after January 15, 2021, the logicians at the Bulgarian Academy of Sciences and the Sofia University “St. Kliment Ohridski” will celebrate together World Logic Day organizing a Joint Meeting of the Algebra and Logic Seminar at the Institute of Mathematics and Informatics of the Bulgarian Academy of Sciences, the Seminar of the Department of Mathematical Logic and Its Applications of the Faculty of Mathematics and Informatics of Sofia University “St. Kliment Ohridski”, the Seminar of Logic at the Institute of Philosophy and Sociology of the Bulgarian Academy of Sciences, and the Department of Artificial Intelligence and Linguistic Technologies of the Institute of Information and Communication Technologies of the Bulgarian Academy of Sciences.
