World Behavior Analysis Day is observed worldwide every March 20, celebrating the field of behavior analysis and commemorating the birthday of its founder, B. F. Skinner. The day was established in December 2020 by a coalition of behavior analysis associations and has been celebrated annually since its inaugural event in 2021. During the week leading up to the day, from March 14 to March 20, various events such as conferences, seminars, webinars, and workshops are organized by behavioral analysis associations and practitioners to promote the discipline. The applied branch of behavior analysis, known as applied behavior analysis (ABA), focuses on improving socially significant behavior and is utilized in various settings, including schools and clinics. Participants can engage in activities like organizing local events, sharing knowledge about behaviorism, and promoting the holiday on social media using the hashtags #WorldBehaviorAnalysisDay and #WBAD.
