Although December has not been designated a special heritage month, it does contain celebratory days that are recognized internationally.

On December 10 in 1948, the United Nations General Assembly adopted the Universal Declaration of Human Rights. The document set forth the basic civil standard of economic, political, and social rights that should be guaranteed to every person. Each December, the commitment to this universal document of rights is renewed and celebrated.  

In addition, the United Nations has established December 3 as the International Day of Persons with Disabilities. This international observance was established to promote an understanding of disability issues and mobilize support for the dignity, rights, and well-being of persons with disabilities. It also aims to foster awareness of the importance of integrating persons with disabilities into every aspect of life.
