International Day of Persons with Disabilities (December 3) was established on December 3, 1992, as a global observance to raise public awareness about the issues and rights of persons with disabilities. The day aims to promote social inclusion and equal opportunities for people with disabilities worldwide. In 1992, the United Nations designated this date as an international observance in the Gregorian calendar to highlight the importance of removing physical and social barriers and supporting the rights of this group. This decision followed the adoption of the World Programme of Action concerning Disabled Persons. Since then, various events and programs have been held annually on this day in many countries to draw attention to the challenges and needs of persons with disabilities. In Iran and many other countries, the day is marked by conferences, exhibitions, and educational workshops. These activities are intended to foster a culture of acceptance and respect for the rights of persons with disabilities and to encourage the creation of inclusive and accessible environments. The observance provides an opportunity to review progress and ongoing challenges in supporting persons with disabilities and serves as a reminder of the importance of their active participation in society.
