Today, 14 January 2026 is UNESCO World Logic Day. http://wld.cipsh.international/ UNESCO has proclaimed January 14th as World Logic Day, a global day dedicated to supporting the development of logic through teaching, research, and public dissemination of the discipline. To this end, many events are happening around the world. See https://wld.cipsh.international/wld2026.html for an overview. As you will see all of January offers great events. Huge thanks to the local organizers! The coordination of World Logic Day 2026 is - for the sixth time - in the hands of the Conseil International de Philosophie et des Sciences Humaines (CIPSH) and its member organization, the Division for Logic, Methodology and Philosophy of Science and Technology of the International Union of History and Philosophy of Science and Technology (DLMPST/IUHPST): https://en.unesco.org/commemorations/worldlogicday http://wld.cipsh.international/ Let's also start thinking about the celebrations in 2027! We invite you to organize a workshop, talk, or other event celebrating the next World Logic Day - January 14, 2027. Let's make it a vibrant and inclusive celebration. World Logic Day is what we make of it. You can register your event to be part of the official list of events! There will be a new competition (on creating riddles), details will be circulated in March. The three winners of this year's design challenge will get an email today and once we get their blessing we will upload the posters.
