International Women's Day is a global day celebrating the social, economic, cultural and political achievements of women - while also marking a call to action for accelerating gender balance.
The first International Women's Day occurred in 1911, supported by over one million people. Today, IWD belongs to all groups collectively everywhere. IWD is not country, group or organization specific.
