Transgender Flag Day is observed worldwide every August 19 and celebrates the transgender pride flag and its creator, Monica Helms, a transgender activist and U.S. Navy veteran. The flag, designed in 1999, features five horizontal stripes in light blue, pink, and white, symbolizing traditional gender associations and inclusivity for those who identify under the transgender umbrella. The flag was first flown at a Pride parade in Phoenix, Arizona, and gained popularity within the LGBTQ+ community, with a significant milestone occurring in 2012 when it was raised at Harvey Milk Plaza in San Francisco on Transgender Day of Remembrance. On August 19, 2014, Helms donated the original flag to the Smithsonian's National Museum of American History, further solidifying its cultural significance. The day is marked by LGBTQ+ organizations, individuals, and allies honoring the flag and its meaning, highlighting the importance of transgender visibility and pride.
