The theme of International Literacy Day 2012 is Literacy and Peace. This theme was adopted by the United Nations Literacy Decade (UNLD) to demonstrate the multiple uses and value that literacy brings to people. For over 40 years now, UNESCO has been celebrating International Literacy Day by reminding the international community that literacy is a human right and the foundation of all learning.
