International Day of Persons with Disabilities (IDPD) is a UN day that is celebrated every year on 3 December.

The day is about promoting the rights and well-being of persons with disabilities at every level of society and development, and to raise awareness of the situation of persons with disabilities in all aspects of political, social, economic, and cultural life. WHO joins the UN in observing this day each year, reinforcing the importance of securing the rights of people with disabilities, so they can participate fully, equally and effectively in society with others, and face no barriers in all aspects of their lives.

A disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Not all disabilities are visible. They may be cognitive, developmental, intellectual, mental, physical, sensory, or a combination of multiple factors.
