Hack Day is an exciting event where people come together to create innovative projects in a short amount of time, usually just 24 hours. Participants, often called hackers, form teams to brainstorm ideas, code, and build prototypes. The atmosphere is filled with creativity and collaboration, as everyone shares their skills and knowledge to bring their ideas to life. At the end of Hack Day, teams present their projects to a panel of judges and fellow participants. This showcase allows everyone to see the amazing work done in such a short period. Prizes are often awarded for the best projects, encouraging friendly competition and inspiring future innovations.
