The United Nations, since 2000, has declared 12 August as International Youth Day (IYD). This is to raise awareness about the issues young people in different countries care about the most. Youth organizations and organizations working with young people are invited to highlight the efforts of young people in creating a better world.
The World Council of Churches has put together an International Youth Day Toolkit to help youth workers prepare our churches to engage in youth issues.
