LGBT History Month is celebrated in October and is a month long observance of lesbian, gay, bisexual and transgender history and gay rights. LGBT History Month was first celebrated in 1994 in the United States, founded by a high school teacher from Missouri named Rodney Wilson. He choose October because National Coming Out Day already was established on October 11th.

October also commemorated the first March on Washington for LGBT Rights and Liberation back on October 14th, 1979.

2012 marked the very first American school districts to celebrate LGBT History Month; the Broward County school district in Florida signed in September to support LGBT Americans, and shortly followed the Los Angeles school district to signed on.

In the UK they celebrate LGBT History Month in February and was instated by Sue Sanders and charity called Schools Out back in February 2005. There were 150 different events that year around the UK.

LGBT History Month is intended to encourage honesty and openness about being LGBT.
