Farmers Market Days is a free reference site for U.S. farmers markets, with state and city pages, a map and filters. It cites USDA and state sources, keeps source names and dates visible, and has a methodology page and a corrections form. Not every listing has market days and hours on file, so check with a market before visiting.
The project aims to make useful, published market information easier to find in one place. It focuses on market days, hours, seasons and food-benefit details, while keeping source names and dates visible so shoppers can judge the information and check with a market before visiting.
