According to wikipedia,
Gay and Lesbian Pride Month is celebrated each year for the month of June. The last Sunday in June is celebrated as Gay Pride Day. On June 2, 2000, President Bill Clinton declared June "Gay & Lesbian Pride Month". In 2009, 2010, and 2011 U.S. President Barack Obama declared June to be Lesbian, Gay, Bisexual, and Transgender Pride Month, stating, “I call upon all Americans to observe this month by fighting prejudice and discrimination in their own lives and everywhere it exists.” The month was chosen to commemorate the 1969 Stonewall riots in Greenwich Village that sparked the modern LGBT liberation movement in the United States.
Several parades are organized to recognize the impact Gay, Lesbian, Bisexual, Transgender and Intersex people have had on the world. Yesterday (Saturday), a record crowd of over 10,000 turned out for Pink Dot at Hong Lim Park on Saturday evening -- more than twice last year's size.
