What is Local Hack Day?

Join us on December 1st, 2018 for MLH's Local Hack Day, a global hackathon and celebration of learning, building, and sharing! Whether you're a first timer who is learning to program or you go to hackathons every weekend, everyone is welcome to participate!

This is MLH's 5th year organizing Local Hack Day. In 2017, the event brought out more than 6,000 participants across 34 countries and 236 cities around the world. This year's event is shaping up to be the biggest one yet!

Where is Local Hack Day?

There are over 300 Local Hack Day locations around the world that you can participate in.  To attend, find the location's page on the Local Hack Day website and register. 

If there isn't a location near you, you can always particiate virtually!

What is a hackathon?

Hackathons are learning focused invention marathons where participants dream up fun, interesting projects and work in small teams to bring them to life over the course of the event.

When you're not working on your project, there are plenty of other things to do like attending educational workshops, making friends, or showing off what you're learning or building. At Local Hack Day you can do these with other participants at your location or participants around the world at other locations!
