What is Local Hack Day?

MLH's Local Hack Day is a series of simultaneous global events designed to spark a passion for technology in your local community. Spend the day getting hands-on experience and collaborating in a welcoming environment at a local event.* Whether you are learning to code or are an expert hacker, Local Hack Day is perfect for you and your community. Learn new skills, build new projects, and share your creations at a Local Hack Day near you.

This year we are doing things differently. You can now host a conference, a hack day, and a demo day for your community. We are focusing on the three important skills - Learning, Building, and Sharing.

*Due to the COVID-19 pandemic, Local Hack Day: Share has moved to an online-only format.

"Our team was able to use Local Hack Day's resources and hackathon model to create a more accessible hackathon for our students. It was a great way to introduce newer hackers into the community, and to encourage participation from all teams. Overall, it really helped convince our administrators to continue supporting hackathons at our school!"
