Bisexual Awareness Week is an annual event observed in September (16-23) to celebrate and recognise the bisexual community. The week is typically marked with various events and activities that promote bisexual visibility and acceptance. 

Bisexual Awareness Week, also referred to as BiWeek, was first celebrated in 2014, and was an extention of Bisexual Visibility Day (23 September), which has been celebrated since 1999. 

Bisexuality is an attraction to more than one gender. Those who identify as bisexual feel a sexual and/or romantic attraction to people of a different gender as well as their own. While this offers a basic definition, bisexual people are a diverse group. Each individual perceives their sexual orientation differently.

The bisexual flag is a pride flag representing bisexuality, bisexual individuals and the bisexual community. The pink stripe represents attraction to the same gender, while the blue stripe represents attraction to the opposite gender. The purple stripe, the resulting “overlap” of the blue and pink stripes, represents attraction to all genders, including non-binary people and those of other gender identities.
