What is the Hour of Code?

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. This grassroots campaign is supported by over 400 partners and 200,000 educators worldwide.

When is the Hour of Code?

The Hour of Code takes place each year during Computer Science Education Week. The 2021 Computer Science Education Week will be December 6-12, but you can host an Hour of Code all year-round. Computer Science Education Week is held annually in recognition of the birthday of computing pioneer Admiral Grace Murray Hopper (December 9, 1906).

Why computer science?

Every student should have the opportunity to learn computer science. It helps nurture problem-solving skills, logic and creativity. By starting early, students will have a foundation for success in any 21st-century career path. See more stats here.
