International Lesbian Day, held on October 8, is a day for lesbians the world over to come together to celebrate lesbian history, diversity and culture.
Recognised annually, the day gives an opportunity for women, families and friends to connect, celebrate and also raise awareness about the importance of community. Although the exact origin of the day remains uncertain, it almost certainly began in Australia/New Zealand.
