The Hour of Code started as a one-hour introduction to computer science, designed to demystify "code", to show that anybody can learn the basics, and to broaden participation in the field of computer science. It has since become a worldwide effort to celebrate computer science, starting with 1-hour coding activities but expanding to all sorts of community efforts. Check out the tutorials and activities.

The 'Hour of Code™'/'Hora del Código®' is a global initiative by Computer Science Education Week (csedweek.org) and Code.org (code.org) to introduce millions of students to one hour of computer science and computer programming.
