Have you ever heard about such a day? We think that everyone should know that the premise of the event is to raise awareness of the fact that women around the world are subject to rape, domestic violence and other forms of violence.

Historically, the international observance is based on date of the 1960 assassination of the three Mirabal sisters who were Dominican political activists. In 1981 the date was marked as a day to combat violence against women more broadly.
