National Coming Out Day is an internationally-observed civil awareness day for the LGBTQ+ community. It is observed on October 11 every year by members of the LGBTQ+ communities and those who stand in solidarity with them. National Coming Out Day is on the anniversary of the 1987 March on Washington for Lesbian and Gay Rights and the first visit of the AIDS Memorial Quilt to Washington DC.
Coming Out Day at Duke is celebrated in conjunction with LGBT History Month which is observed in October.
LGBT History Month was first celebrated in 1994 and was founded by Rodney Wilson, a Missouri high school teacher. LGBT History Month "provides role models, builds community and makes the civil rights statement about our extraordinary national and international contributions."
