Most, but not all, of the markets are sponsored by the city and occur on one day of the week, with the exception of a few of the more popular ones, such as the Green City Market. Each market is open from 7:00 a.m. to 2:00 p.m., unless otherwise indicated. Over time the locations and days of some markets have shifted as the city is constantly working to provide balanced coverage to different neighborhoods throughout the week. The only day that no markets are open is Friday. While most markets begin on the first week of the month listed, shoppers should check their local market before visiting, as a few begin in the second week of the month.
