On March 23-30 2026 the NYC Open Data Team at the Office of Technology and Innovation (OTI), BetaNYC, and Data through Design presented NYC Open Data Week 2026. Every March, New Yorkers come together online and across the five boroughs to celebrate public data in New York City and mark the anniversary of the City’s first open data law, which was signed on March 7, 2012. Coincidentally, the first weekend of March is also International Open Data Day. Throughout Open Data Week, NYC’s civic tech and open data communities rally to offer opportunities for more people to learn about and engage with municipal public data. The week culminates with the NYC School of Data.
