9am-5pm Monday Thursday Friday Saturday
Marketplace & Flea Market: Mon & Thu-Sat: 9 am-5pm --- South Side Market: Mon-Fri: 9 am-7pm, Saturday: 9 am-6pm
Officially 9:00 - 6:00 depending on the weekday, but when I arrived on 5:20 Saturday most of the vendors were packed up. They're also open on Tuesdays now for the same hours.
