National Coming Out Day (NCOD) is an annual LGBT awareness day observed on October 11 to support anyone “coming out of the closet”. First celebrated in the United States in 1988, the initial idea was grounded in the feminist and gay liberation spirit of the personal being political, and the emphasis on the most basic form of activism being coming out to family, friends, and colleagues, and living life as an openly lesbian or gay person.
