December 3 is International Day of Persons with Disabilities (IDPD). Since 1992, the United Nations’ IDPD has been celebrated globally each year on 3 December to promote an understanding of disability issues and mobilize support for the dignity, rights, and well-being of persons with disabilities (PwD). It also seeks to increase awareness of gains to be derived from the integration of PwD in every aspect of political, social, economic, and cultural life. Each year the day focuses on a different issue.
