International Day of the Girl Child is an international observance day declared by the United Nations; it is also called the Day of the Girl and the International Day of the Girl. October 11, 2011, was the first Day of the Girl. The observation supports more opportunity for girls and increases awareness of gender inequality faced by girls worldwide based upon their gender. This inequality includes areas such as right to education/access to education, nutrition, legal rights, medical care, and protection from discrimination, violence against women and unfree child marriage.
The International Day of the Girl Child initiative began as a project of Plan International, a non-governmental organization that operates worldwide. The idea for an international day of observance and celebration grew out of Plan International’s Because I Am a Girl campaign, which raises awareness of the importance of nurturing girls globally and in developing countries in particular. Plan International representatives in Canada approached the Canadian federal government to seek support for the initiative. A coalition of supporters raised awareness of the initiative internationally.
International Day of the Girl Child was formally proposed as a resolution by Canada in the United Nations General Assembly. Rona Ambrose, Canada’s Minister for the Status of Women, sponsored the resolution; a delegation of women and girls made presentations in support of the initiative at the 55th United Nations Commission on the Status of Women. On December 19, 2011, the United Nations General Assembly voted to pass a resolution adopting October 11, 2012 as the inaugural International Day of the Girl Child. The resolution states that the Day of the Girl recognizes

Each year’s Day of the Girl has a theme; the first was “ending child marriage”, the second, in 2013, was “innovating for girl’s education”, and the third, in 2014, was “Empowering Adolescent Girls: Ending the Cycle of Violence.”
