Chick-fil-A restaurants typically open at 6:30 a.m. and close at 9 p.m. from Monday through Saturday. They are closed on Sundays and also on Thanksgiving Day and Christmas Day to allow their team members to spend time with family and friends. For lunch, Chick-fil-A starts serving at 10:30 a.m. Monday through Saturday. Hours may vary slightly by location, so it's a good idea to check the specific restaurant hours through their website or app. If you are asking about the opening day for a specific new Chick-fil-A location, for example, one in McHenry or Mississauga, these vary by location and can be announced by the company closer to the opening date. For instance, a new McHenry location was noted to offer free food on its opening day in late August 2025. For regular Chick-fil-A store hours, most operate from early morning (6:30 a.m. or 10:30 a.m. in some Canadian locations) until 9 or 10 p.m. Monday through Saturday.
