National Day of Civic Hacking2021 · Date · History
Archived White House material establishes the first nationwide National Day of Civic Hacking on 1–2 June 2013. Later White House and Code for America sources document continuing organizer-led editions, including the ninth annual Code for America event on 18 September 2021. The reviewed evidence does not establish a 2026 edition or a permanent recurrence rule, so publication is historical/legacy and edition-specific.
About National Day of Civic Hacking
National Day of Civic Hacking was a United States civic-technology day of action that brought residents, technologists, designers, public agencies and community groups together around public data and local problem-solving.
The strongest reviewed evidence supports a documented historical campaign with organizer-set dates, not a fixed-date holiday that should automatically appear on every current calendar.
Why National Day of Civic Hacking matters
In this context, “civic hacking” means collaborative, practical problem-solving for public and community needs. Code for America described it as broader than coding alone, involving people with skills in research, design, project management, data and community leadership.
The term does not authorize intrusion into computer systems. Responsible participation uses public or properly authorized data, follows privacy and security rules, and stays within the law and the permissions of the organization involved.
History of National Day of Civic Hacking
Archived White House material announced the first nationwide National Day of Civic Hacking for June 1–2, 2013, describing it as the first time local developers around the country would unite around a shared civic problem-solving mission.
By 2015, the White House called the June 6 event the third annual National Day of Civic Hacking and said it was organized by Code for America with coordination from NASA and SecondMuse, with support from the White House Office of Science and Technology Policy and other agencies.
Federal material documents a June 4 edition in 2016. Code for America later called September 18, 2021 its ninth annual National Day of Civic Hacking and used that edition for a coordinated Reimagine 911 project.
Because documented dates changed across editions and the current review did not locate a 2026 Code for America edition, this guide treats National Day of Civic Hacking as a historical/legacy organizer-run event unless a future edition is independently re-verified.

How to Observe National Day of Civic Hacking
Work on a clearly defined community problem using public, open or properly authorized data rather than attempting to access systems without permission.
Partner with residents and subject-matter experts before building a tool so the project responds to a real community need rather than a guessed one.
Review privacy, security, accessibility and data-minimization needs before collecting or publishing information.
Document the project, its assumptions and any limitations so another community group can understand or safely reuse the work.
If you want to join a current civic-tech event, verify the organizer, date and participation rules for the present year instead of relying on an old National Day of Civic Hacking date.
