International Day of Persons with Disabilities is celebrated every December 3. It used to be called International Day of Disabled Persons but was changed to International Day of Persons with Disabilities by UN General Assembly resolution 62/127 on 18 December 2007.
This year's theme is “Realigning the Millennium Development Goals for All: Empowerment of Persons with Disabilities and their Communities Around the World".
Here's an editorial from Manila Bulletin regarding the 2009 International Day of Persons with Disabilities.
To provide an opportunity for governments, organizations of disabled persons, and all in society to focus on the freedoms and potentials of persons with disabilities, International Day of Disabled Persons is observed on December 3 each year.
The theme for 2009, “Realigning the Millennium Development Goals for All: Empowerment of Persons with Disabilities and their Communities Around the World,’’ stresses the need to develop programs that raise the profile of disability issues in both the developed and developing world and identify existing needs and priorities, and calls for greater efforts to find solutions which are suited to the technological and economic conditions of the disabled. These actions require people with disabilities to be visible and to be given a voice that will qualify them to be adequately represented in decision making. [Source]
