From The United Nations:
On December 19, 2011, the United Nations General Assembly adopted Resolution 66/170 to declare 11 October as the International Day of the Girl Child, to recognize girls’ rights and the unique challenges girls face around the world.
In recognition of the importance of investing in and empowering girls during adolescence and preventing and eliminating the various forms of violence they experience, the theme of International Day of the Girl Child for 2014 is Empowering Adolescent Girls: Ending the Cycle of Violence.
