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/wld2025.html
for an overview.
 
The coordination of World Logic Day 2025 is - for the fifth 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):

Let's also start thinking about the celebrations in 2026! We invite you to organize a workshop, talk, or other event celebrating the next World Logic Day - January 14, 2026. 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!
 
Additionally there will be a
WORLD LOGIC DAY GRAPHIC DESIGN CHALLENGE To celebrate World Logic Day 2026 (again on January 14)

 Logic, traditionally seen as the domain of pure thought and reason, is notoriously difficult to visualise. 
Finding ways to express the most fundamental laws that govern the human process of reasoning without words and in pictures is a true challenge: we should love to see your attempts to overcome it.

 The theme of World Logic Day 2026 will be "Logic & Diversity" and we would be particularly happy with submissions that focus on aspects that fit with the theme, e.g., the question of whether there is one true logic or several, the question whether logical systems can be in conflict with each other, etc.
We encourages creative interpretations, reflecting on how logic interacts with the rich tapestry of diverse cultures, perspectives, and ideas.

In order to participate in your WLD Graphic Design Challenge, please submit a one-page A4 file with a visualisation of logic or a particular logical phenomenon that works with as few words as possible by June 30, 2025. 
You may accompany your graphic design with a brief verbal description of your design (at most 200 words).

Your graphic designs will play a role at World Logic Day 2026 on 14 January 2026:
We expect to include selected submission on the WLD website, organise an exhibition of selected submissions, and invite the winner of the WLD Graphic Design Challenge to a workshop in Europe (pending funding).
